Survival Skills | Guide to Poisonous Plants

Survival Techniques: Poisonous plant Episode One from Jeff Mason on Myspace.

 

Poisonous plants are everywhere. They’re in the woods, the forests and the mountains. In fact some of them may even be in your garden. This makes bugging out look like a dangerous proposition when the SHTF.

However, these plants would not cause harm if you did not eat or touch them. As you read our guide, you will realize that it is actually simple and easy to avoid these poisonous plants. Just stick to your regular food and avoid the bitter stuff. Avoid eating seeds and flowers.

Don’t eat anything unfamiliar and make sure you have adequate body covering when you’re out there. Wear thick or insulated clothing as well as tough and durable boots. Never assume that because you saw a deer or goat eat a plant, you can eat it, too.

Identifying poisonous plants may be a daunting task especially in emergency situations, but remember that your goal is to survive.

1. Aconite (Aconitum spp.)

 

A guide to poisonous plants would not be complete without the monkshood. Via cedarvalleyarboretum

Garden monkshood is native to western and central Europe, but is grown widely in North America as a garden ornamental. Its showy spires of deep purple flowers are striking in late fall; the hood-like shapes of the flowers give the plant its common name. Although extracts of the plant are used homeopathically in low doses to treat inflammation, these compounds are poisonous — even deadly. Continue reading

2. Agave/century plant (Agave spp.)

 

Poisonous plants can be found almost everywhere like the agave which is often used for landscaping. Via austinnativelandscaping

Agave has a toxic sap that immediately causes pain and burning upon contact with skin. Typically the skin will also turn red and may begin to develop blisters soon after exposure to agave. Exposed skin may also be sensitive to sunlight. If ingested, the saponin in the agave plant can have serious consequences including kidney and liver damage. Click here to read the whole article.

 

3. Almond seeds (Prunus spp.)

 

Poisonous plants have parts that have the highest concentration of toxins, and most of them can be found in the seeds. Via universalcats.com

Bitter almonds contain amygdalin and prunasin, which are cyanogenic compounds. Human intestines contain an enzyme that is capable of converting these substances to cyanide. Poisoning from cyanide and death have occurred following bitter almond consumption. The U.S Food and Drug Administration, however, prohibits the sale of unprocessed bitter almonds because of the risk of cyanide toxicity. The type of almonds you find at the grocer are sweet almonds, which are safe to eat. See more at

4. Angel’s trumpet (Brugmansia spp.)

 

More often than not, beautiful flora turn out to be poisonous plants. Via thevaliens.com

Large, pendulous, trumpet-shaped brugmansia flowers perfume the air with their fragrance. With a common name as heavenly as “angel’s trumpet,” it’s hard to imagine that brugmansia (Brugmansia spp.) can have such devilish consequences. But the California Poison Control System ranks brugmansia in Class 1 — its most toxic plant category. Poisonous brugmansia sap may cause vision problems, confusion and elevated heart rates.

5. Apple seeds (Malus spp.)

 

The very common apple is included in this list of poisonous plants because of the toxins found in the seeds. Via theparrotuniversity.com

Apple seeds are very often eaten accidentally but you would need to chew and consume a fairly high number to get sick. There are not enough seeds in one apple to kill, but it is absolutely possible to eat enough to die. Read the whole article here

 

6. Apricot seeds (Prunus spp.)

 

You wouldn’t think of the apricot as one of the poisonous plants but once again, the seeds are toxic. Via wakeup-world

Apricot kernel contains a toxic chemical known as amygdalin. In the body this chemical is converted to cyanide, which is poisonous. There was interest in using apricot kernel to fight cancer because it was thought that amygdalin was taken up first by cancer cells and converted to cyanide. It was hoped that the cyanide would harm only the tumor. But research has shown that this is not true. The amygdalin is actually converted to cyanide in the stomach. The cyanide then goes throughout the body, where it can cause serious harm, including death. Click here for the full post.

 

7. Autumn crocus/Meadow saffron (Colchicum autumnale)

 

Some of its common names may be amusing but make no mistake, meadow saffrons are still poisonous plants. Via galleryhip

The active principle is said to be an alkaline substance of a very poisonous nature called Colchinine. It is acrid, sedative, and acts upon all the secreting organs, particularly the bowels and kidneys. It is apt to cause undue depression, and in large doses acts as an irritant poison. Dr. Lindley relates the case of a woman who was poisoned by the sprouts of Colchicum, which had been thrown away in Covent Garden Market and which she mistook for onions. Learn more..

 

8. Azalea (Rhododendron spp.)

 

The azalea is positively one of the most poisonous plants, so poisonous in fact that honey made from them can still be toxic. Via texomamedicalcenter

Consumption of leaves and/or quantities of flowers by livestock or children. Even the continual consumption of honey from rhododendron and azalea flowers can be poisonous. This effect has been known since 400 BCE, when honey was a chief source of sweetness in Europe and Asia. Greek soldiers of that era were poisoned by prolonged use of rhododendron honey.
The human digestive tract is capable of breaking down small doses of andromedotoxins into harmless compounds, so human fatalities from eating these plants are rare. However, victims who consume a lot suffer from nausea, vomiting, abdominal upset, and low blood pressure. People who regularly eat affected honey can suffer chronic symptoms of this sort, as well. See more

9. Bittersweet (Celastrus scandens)

 

Its name alone will tell you it’s one of those poisonous plants you should avoid. Via brandeis.edu

American bittersweet is a woody vine often used in fall wreaths and dried flower arrangements. Its orange-yellow berries are three-part capsules with a seed in each part. They grow at the point where the leaves join the stems. Eating American Bittersweet berries can cause stomach upset and diarrhea. To read the full article, click here.

 

10. Black cherry seeds (Prunus serotina)

 

Poisonous plants tend to make the fruit and only the fruit edible to animals and man. Via wildmanstevebrill.com

Poison Delivery Mode: Ingestion
Symptoms: Gasping, weakness, excitement, pupil dilation, spasms, convulsions, coma, respiratory failure
Toxic Principle: Cyanogenic glycoside, amygdalin
Severity: HIGHLY TOXIC, MAY BE FATAL IF EATEN! Read more

 

11. Black henbane (Hyoscyamus niger)

 

The black henbane makes it to the list of poisonous plants because it has caused coma in some cases. Via invasive.org

All plant parts of black henbane are considered highly toxic because of alkaloids hyoscymine and scopolamine, and can be fatal if eaten. It is poisonous to all livestock and humans, even at low doses. Symptoms of poisoning include: Salivation, headache, nausea, vomiting, diarrhea, rapid pulse, convulsions, and coma. It can cause skin irritation if it is touched with bare skin.
Black henbane has the bad reputation of a plant that has poisoned and killed many people. 
Affective herbicides include: picloram, dicamba, 2,4-D and metsilfuron.
The two alkaloids (hyoscyamine and scopolamine) are useful sedative/ anti-spasmodic drugs when used under controlled conditions.
In the Middle Ages, black henbane was widely used in Germany to augment the inebriating qualities of beer. The names of many German towns originate from the word Bilsen–henbane. Later on, the word was transformed to Pilsen to name the famous Pilsen beer. It took many years to prohibit the use of henbane in brewing after numerous cases of poisonings. Read more

12. Black locust seeds (Robinia pseudoacacia)

 

When it comes to poisonous plants, always remember that death is possible. The seeds of the black locust is one example. Via portraitoftheearth.com

The bark, leaves and seeds of black locust all contain the toxalbumins robin, phasin and robitin, which can produce severe gastrointestinal irritation, weakness, blood cell, liver and kidney damage—and in some cases, even death. See more

 

13. Black nightshade (Solanum spp.)

 

Almost all members of the nightshade family are poisonous plants, including this one. Via rufino-osorio.blogspot.com

The name says it all — both the foliage and the berries of this plant are extremely toxic. Deadly nightshade has a long, colorful history of use as a poison, but what many people don’t realize is that the nightshade family includes common food plants, including potatoes, tomatoes, eggplants and chili peppers. In fact, all of these plants contain toxins — usually in their foliage — that can be harmful. In particular, humans and pets should avoid potato and tomato foliage and vines in the garden.

14. Cardinal flower/Lobelia (Lobelia spp.)

 

There is more to the bright red color than being similar to a cardinal’s robe. Via hummingbirdgardener.com

Lobelia cardinalis, or cardinal flower, is a swamp-loving perennial native to the Americas. It is poisonous to humans, cats and dogs. Severity of symptoms varies among people. Children tend to react more seriously than adults. The culprit, lobeline. This naturally occuring chemical is commonly found in plants. Signs of poisoning include depression, excessive salivation, mental confusion, irregular heart rhythm, vomiting and abdominal pain.Continue reading

15. Carolina jessamine (Gelsemium sempervirens)

 

Some poisonous plants look like other harmless varieties. The Carolina jessamine looks a lot like honeysuckle. Via mrjacksfarm.com

This high-climbing vine is very common in parts of the South, frequently found in abandoned fields and climbing high into the canopies of pine forests. It is quite adaptable and tenacious, with no serious disease or insect problems. These qualities, along with its glossy, evergreen leaves and waxy, trumpet-shaped flowers, have made it a mainstay of the suburban landscape in the Southeast. The flowers, leaves, and roots are poisonous and may be lethal to humans and livestock. The species nectar may also be toxic to honeybees if too much is consumed and honey made from Carolina Jessamine nectar may be toxic to humans. Rankins Yellow Jessamine, also known as Swamp Jessamine (G. rankinii), with odorless flowers, occurs in swamps from North Carolina to Florida. Learn more

16. Carolina laurel cherry (Prunus caroliniana)

 

This is one of the most poisonous plants because of its hydrocyanic acid content, a type of cyanide. Via msucares.com

With a natural range extending from southern North Carolina west to east Texas, Carolina laurel cherry is a dense shrub or small tree, 15-36 ft. tall, with a pyramidal to oval outline. Leaves are firm, smooth, evergreen, narrowly elliptic, tapered to a pointed tip and equally tapered to the base. Margins are smooth on reproductive trees, with narrow, pointed teeth on saplings and root sprouts. Upper surface is dark green and shiny, the lower surface lighter and duller. The leaves have a taste suggestive of almond flavoring and are poisonous when eaten. Read the whole article here.

17. Castor Bean (Ricinus communis)

 

Castor oil may be used in alternative medicine, but the beans make it one of the poisonous plants. Via zwallpix.com

Widely grown as an ornamental, the castor bean is an attractive plant native to Africa. While the processed seeds are the source of castor oil, they naturally contain the poison ricin and are deadly in small amounts. It only takes one or two seeds to kill a child and up to eight to kill an adult. Ricin works by inhibiting the synthesis of proteins within cells and can cause severe vomiting, diarrhea, seizures, and even death. The poison was used in 1978 to assassinate Georgi Markov, a journalist who spoke out against the Bulgarian government, and has been mailed to several U.S. politicians in failed terrorism attempts. Most fatalities are the result of accidental ingestion by children and pets. To read the full article, click here.

 

18. Cestrum/Jessamines (Cestrum spp.)

 

The cestrum jessamines are some of the poisonous plants that have berries which are toxic whether green or ripe. Via davesgarden.com

Common names: Day-blooming jessamine (jasmine), night-blooming jessamine (jasmine), Chinese inkberry.
Toxins: Solanine (a cholinesterase-inhibiting compound) predominates in unripe berries, whereas tropane alkaloids (which are like atropine) are prevalent in the ripe berry. Saponins, alkaloids, and traces of nicotine are also found in plants. Cestrum diurnum contains 1,25-dihydroxyvitamin D glucoside.
Toxic parts: Fruit, leaves, and sap are poisonous.
Signs: Both solanine and tropane may mimic atropine poisoning (mydriasis, tachycardia, xerostorma, dyspnea, ileus, urinary retention, CNS stimulation followed by depression, paralysis, seizures). If solanine predominates, mild to severe gastrointestinal signs may predominate. Normal to increased borborygmi may indicate predominance of solanine, whereas lack of bowel sounds may hint at an atropine-like toxin. Click here to read the whole article.

 

19. Cherry seeds (Prunus spp.)

 

The luscious cherry may surprise you that it made the poisonous plants list, but the seeds are quite toxic. Via coffeebreakconversations

 

A single cherry yields roughly 0.17 grams of lethal cyanide per gram of seed, so depending on the size of the kernel, ingesting just one or two freshly crushed pits can lead to death. Read more at  http://www.bonappetit.com/test-kitchen/ingredients/slideshow/foods-that-can-kill-you/?slide=1

 

20. Chinaberry (Melia azedarach)

 

Apart from being one of the poisonous plants, the chinaberry tree has also become a nuisance to the country’s landscape. Via sarinalandcare

The chinaberry tree has been introduced to America and some other temperate countries. When it was first brought into the country it was considered an ornamental tree, and in some areas, plants and seeds can still be bought. Due to its toxicity, it is often considered a pest species in many American states to which it has spread. It is a highly invasive tree which has a tendency to spread rapidly, and is extremely difficult to uproot once it is established.

 

21. Chinese lantern (Physalis spp.)

 

Most poisonous plants are attractive and the Chinese lantern is one of them. Via Texas heirloom tomatoes

We grow these for the colorful, fun pods and the ripened fruits are sometimes used to make jams and jellies, but use extreme caution unless you know what you are doing. The unripe berries can be highly toxic and possibly fatal. Poisonous Parts: Unripe berries, leaves. Symptoms: Headache, stomachache, vomiting, diarrhea, low temperature, dilated pupils, breathing problems and numbness. Click here to read the whole article.

22. Chokecherry (Prunus virginiana)

 

It’s always a good thing to name plants based on what they are, poisonous plants. Via iastate.edu

Most parts of chokecherry are toxic to humans and livestock. Digestion of chokecherry seeds, leaves, twigs and bark by enzymes in the stomach releases cyanide (also called hydrocyanic or prussic acid). Cyanide poisoning can occur with fresh, bruised, wilted or dried foliage. It is possible for a person or animal to die of cyanide poisoning if not treated within minutes of ingestion. Cases of poisoning in livestock have been reported. However, it is not usual for such poisonings to occur at times when other, more palatable forage is available. Cases of poisoning have been reported for children who chewed on twigs, or ate the cherries without discarding the pits. The fleshy portion of the chokecherry fruit is not poisonous and can be safely eaten, although it is extremely tart. See more at

26. Cotoneaster (Cotoneaster spp.)

 

Cyanogenic glycosides in poisonous plants like the cotoneaster are converted to cyanide during digestion. Via 99roots.com

 

Cotoneaster is an evergreen shrub that tends to grow upright with long branches rather than as a bush. Its bright orange berries grow in clusters so thick that the branches cannot be seen. Cotoneaster is poisonous in large amounts and may cause trouble breathing, weakness and seizures. Read the whole article here.

 

27. Crabapple seeds (Malus spp.)

 

Crabapples are similar to apples, poisonous plants whose toxins are found in the seeds. Via perverdonk.com

Crabapples are essentially the same species as apple trees. The seeds of both of these trees contain a form of cyanide called cyanogenic glycosides. Cyanide is a toxic, potentially fatal poison. However, the average American eats around 16.9 pounds of fresh apples every year and reports no toxic effects. Despite the presence of cyanide in the seeds, most people don’t eat the core. Even when apple seeds are ingested, they usually pass through the gut without being broken down. You would have to eat lots of crabapple seeds and grind or chew them up for the cyanide to take effect. Read more

28. Crow’s poison/False garlic (Nothoscordum bivalve)

 

Poisonous plants resemble edible plants and in this case crow poison looks like garlic. Via wildflower.org

This plant should not be eaten. Some references list this species as poisonous to humans. The jury is still out about its toxicity to crows. Learn more

 

29. Daphne (Daphne spp.)

 

Like some poisonous plants, the bark, sap and berries of daphne have the most toxins. Via pbase.com

Daphne, also called spurge laurel, lady laurel, paradise plant, or dwarf bay, is a small shrub about 1–1.5 meters high and very popular in North America. All parts of Daphne contain extremely active toxins, but the greatest concentrations occur in the bark, sap and berries. Some researchers suggest that Daphne’s extracts may have potential for treating leukemia; the plant is also known to be co-carcinogenic in the presence of low doses of carcinogenic compounds.
The showy colors of the berries often attract children, so if you have Daphne in your garden, care enough to keep them away from it. Even a single berry chewed but not swallowed can cause intense burning in the throat and mouth. Consumption of a few berries can cause upset stomach, headaches, diarrhea, delirium, and convulsions. If the victim falls into a coma, death can ensue. Read more at

30. Deadly nightshade (Atropa belladonna)

 

Of all the poisonous plants, the deadly nightshade is one of the most popular. Via offthehookastronomy

According to legend, Macbeth’s soldiers poisoned the invading Danes with wine made from the sweet fruit of deadly nightshade. Indeed, it is the sweetness of the berries that often lures children and unwitting adults to consume this lethal plant. A native of wooded or waste areas in central and southern Eurasia, deadly nightshade has dull green leaves and shiny black berries about the size of cherries. Nightshade contains atropine and scopolamine in its stems, leaves, berries, and roots, and causes paralysis in the involuntary muscles of the body, including the heart. Even physical contact with the leaves may cause skin irritation. Read the full post here.

31. Death camas (Zigadenus spp.)

 

Most parts of poisonous plants have toxin in them, like the death camas. Via victoriadailyphoto

33. Doll’s-eyes/White baneberry (Actaea pachypoda)

 

Some poisonous plants give away the fact from their looks alone. Via ncwildflower

It’s a good thing the creepy-looking berries of this plant aren’t enticing, because consuming the fruit of a doll’s eye plant (or white baneberry) could kill you. The berries contain cardiogenic toxins that can have an immediate sedative effect on cardiac muscle tissue. Ingestion of the berries can lead to cardiac arrest and death.

Again, all the parts of this plant are poisonous. One should avoid eye contact with the juices which can result in intense pain and swelling. It is a very popular indoor pot plant as it is useful for purifying indoor air. Read the whole article here.

 

35. Elderberry (Sambucus spp.)

 

The elderberry is yet another one of those poisonous plants containing toxic alkaloids. Via marlahanan.com

The indigenous elder tree of the western United States, Sambucus mexicana, can grow to 30 feet and produces small (1/4-inch), globular, nearly black berries that can be covered with a white bloom at maturity. The berries are juicy and edible when mature. The cooked berries are commonly eaten in pies and jams, and berry juice can be fermented into wine. The fresh leaves, flowers, bark, young buds, and roots contain a bitter alkaloid and also a glucoside that, under certain conditions, can produce hydrocyanic acid. The amount of acid produced is usually greatest in young leaves. There may be other toxic constituents in this plant. The root is probably the most poisonous and may be responsible for occasional pig deaths; cattle and sheep have died after eating leaves and young shoots. To read the full article, click here.

36. English laurel (Prunus laurocerasus)

 

Some poisonous plants are invasive and the English laurel is an example. Via nelsonnursery.com

Also known as English laurel or common laurel, cherry laurel (Prunus laurocerasus) is an innocuous-looking small tree or large shrub that is commonly used as a hedging, specimen or border plant. Ingesting any part of the poisonous plant, especially the leaves or seeds, can cause potentially fatal respiratory problems. See more

37. English yew seeds (Taxus baccata)

 

Perhaps poisonous plants do not want their seeds to be eaten so there are toxins in them. Via berlinplants.wordpress.com

The English yew is an evergreen tree with needlelike leaves and red arils, or fleshy seed-coverings. It grows to a height of 60 to 70 feet (18.3 to 21.3 meters) and is found throughout Great Britain, but is also cultivated in the southern United States. Every part of the tree is toxic due to taxine alkaloids, except for the aril flesh.

Poisonous Parts: Green, unripened berries, leaves (skin irritant) Symptoms: vomiting, diarrhea, dilated pupils, trouble breathing. Continue reading

 

47. Larkspur (Delphinium spp.)

 

The larkspur is a member of the monkshood family of poisonous plants. Via lovejoyfarms.com

Like its cousin monkshood, larkspur (delphinium) is a highly popular ornamental plant, often planted in gardens for their dramatic spikes of showy blue blossoms. Larkspur is so pretty that children often just can’t resist touching them, but even brief contact with the flowers or leaves can irritate the skin. And, if you ignore the warning sign of this plant’s strong, acrid taste, you could die – it’s packed full of potent alkaloids. Before keeling over from respiratory paralysis, you’ll experience excitability, disorientation, muscle tremors, stiffness, weakness and seizures. Click here for the full post.

 

48. Loquat seeds (Eriobotrya japonica)

 

Poisonous plants have deadly effects like the seeds of the loquat. Via pixgood

Loquat is a shrubby plant which bears clusters of small white flowers and largish yellow fleshy fruit. The plant is often used in gardens as an ornamental plant. The kernel from inside the seeds contains a chemical called cyanogenic glycoside which can be poisonous if eaten in large quantities.

Poisonous plants can deceive through their beauty. Via uwlax.edu

Catharanthus rosea (formerly Vinca rosea), the Madagascar periwinkle, does contain a group of alkaloids including vinchristine and vinblastine both of which are used in chemotherapy. Chemotherapy is, of course, controlled poisoning. Learn more

50. Manchineel, manzanilla de la muerte (Hippomane mancinella)

 

Of all the world’s poisonous plants, the manchineel holds the title for the most dangerous. Via tree-nation.com

The Manchineel tree does not like company. If you brush up against the tree, the white sap it produces is liable to produce a violent allergic reaction on your skin. Standing beneath the tree during a rainstorm will cause any skin that comes in contact with runoff from the tree to blister.
These epidermal effects are caused by the powerful irritant phorbol, just one of the many toxins found in the tree’s milky sap. Ingesting the tree’s fruit, pictured here, is often fatal on account of its physostignmine content, which can lead to complications involving naseau, vomiting, diarrhea, and seizures. Basically, don’t mess with the manchineel; there’s a reason it’s called “the little apple of death.” You won’t like it, and it definitely doesn’t like you.

51. Marsh marigold (Caltha palustris)

 

This is one of the poisonous plants to avoid when you’re in the marshes. Via auntiedogmasgardenspot

Marsh Marigolds are considered edible with caution and careful preparation; they are mildly toxic which contributes to their apparent utility as herbal medicine. After harvesting, the leaves must be soaked in two to three changes of boiling water to remove the poisonous constituents, the result a spinach-like green. The tightly closed buds can be pickled and used on salads much like capers, following the same decantation used for the leaves. However, the buds must be stored for at least a month before consumption; the pickling fluid should not be ingested. The consumption of raw leaves or buds without proper preparation will result in irritation and burning of the mucous membranes of the throat and nasal passages. The poisons, once ingested, can cause vomiting, bloody diarrhea, fainting and convulsions. To read the full article, click here.

Some poisonous plants look like the edible variety so be very careful. Via cornell.edu

Moonseed is a woody vine with cluster of several small fruits, or drupes, which resemble grapes. This stone fruit plant is generally found in eastern North America, and it is extremely toxic for humans, if ingested, though birds can eat it. They have been mistaken by people foraging for wild grapes, but fruits of Canada Moonseed can be fatal, so care needs to be taken.
The key to recognizing moonseed drupes is that they have only one large crescent-shaped seed, while grapes have many seeds. To read the full article, click here.

54. Morning glory seeds (Ipomoea spp.)

 

When you learn about these poisonous plants, it’s easy to see that the seeds are dangerous. Via gardeningknowhow.com

Hallucinations are the predominant effect after ingesting morning glory seeds. Ingesting 200-300 seeds produces an effect equivalent to 300 micro g of LSD. Vivid visual and tactile hallucinations, as well as increased awareness of colors have been described. Symptoms include facial flushing, nausea, mydriasis, diarrhea, and hypotension (Spoerke and Smolinske 1990). Ipomoea tricolor has a long history of use as a human hallucinogen in southern Mexico, where the seeds were used in the preparation of a drink (Fuller and McClintock 1986). A single undocumented case of poisoning of a pet cat (after ingestion of seeds) has come to our attention. The cat showed erratic behavior and “looked like a lunatic”. Click here for the full post.

 

55. Mountain laurel (Kalmia latifolia)

Although many people might have been made ill by mountain laurel and made a full recovery, the potency of the poison should not be ignored. The progression from initial ingestion to death can be quite rapid in a person who has health issues. The main toxin is called andromedo toxin. This toxin acts on blood circulation by lowering the blood pressure. This leads to drowsiness. The drowsiness allows the toxin to concentrate until it can attack the central nervous system. Convulsions occur, which can be quite severe, with death being preceded by a sort of creeping paralysis. Continue reading

Only the ripe fruit is edible, the rest are poisonous. Via 2livelong

Officially known as Carissa macrocarpa (kuh-RISS-uh mack-roe-KAR-puh) the Natal Plum is part of the Dogbane family. The botanical name for that family is Apocynaceae which is Greek for “keep it away from the dog” meaning it kills them easily. It does us, too. Nearly all parts of the Natal Plum are poisonous, like the Oleander, except for the red-ripe fruit. See more at http://www.eattheweeds.com/natal-plums-num-num/
