Wild Mustard and Wild Radish look very similar. Photo by Green Deane

Blossoms can range from yellow to white. Photo by Green Deane

Mustards like chilly weather, or at least locally they do. You can see Wild Mustards and Wild Radish not only along roadsides now but in various fields from farm land to ignored citrus groves. The two species are used interchangeably and look similar. However Wild Radishes tend to be serpentine rather than straight and tall like Wild Mustard. They also have lumpy seed pods, or, more lumpy than mustard seed pods. Usually you will find a stand of one or the other. I don’t recall finding both in the same patch. Blossom colors can range from yellow to white with streaks of purple. But the leaves always have the biggest lobe on the end farthest from the plant. Look for them in sunny areas with fertile soil. Not native they came from Eurasia in the 1700s. And note the seeds can remain viable in the soil for up to 60 years. To read more Wild Radish go here, and for Wild Mustard, here.

These hibiscus blossoms never open. Photo by Green Deane

We saw several species blooming this past weekend in my foraging class. The Hibiscus were happy including the “Sleepy Hibiscus.” It’s a fairly easy shrub to identify because the bright red blossoms never unfurl. Also blossoming was the Bauhinia. It’s a tree that is both easy and challenging at the same time. The blossoms are edible, look nice in salads. Some of the species have edible seeds and some do not. (They are in the pea family and most pea trees — most not all — do not have edible seeds.) Sorting out which Bauhinia you have can be a challenge, nearly as bad as sorting out which Cereus you have. Like the Cereus cactus there are several man-made hybrids and perhaps even some fake botanical names. It can make species identification a real headache though as far as I know all the blossoms are edible. Only “discovered” 111 years ago the blossom of the Bauhinia blakeana is the emblem of Hong Kong. You can read about the Bauhinia here.

Surinam Cherries have eight ribs.

This newsletter has mentioned in previous editions this fall how many species have been blooming out-of-season perhaps because of the rain brought by Hurricane Irma. As in previous classes we saw some grapes blossoming in early December when they should be setting in the spring. But perhaps the most out-of-season display was Surinam Cherries in fruit, both red and black. I had Suriname Cherries in my yard for many years. They are indeed a springtime fruit though occasionally one or two fruit would pop up at the end of summer. This time, however, there was a lot of ripe fruit which the foraging class enjoyed. It was also an opportunity for me. I rarely see Black Suriname Cherries and think they have a superior flavor. But I’ve had a hard time starting them from seeds. This time I got a lot of seeds to try and it gives me a head start on spring. To read about the Suriname Cherry go here.

Chickweed has five deeply incised petals. Photo by Green Deane

Real chickweed will soon arrive. If you want to sample it in a variety of ways you have a couple of months at best. I usually find chickweed locally between Christmas and Valentine’s Day. It can be found earlier and occasionally after Valentine’s Day. But those two holidays mark the practical beginning and end of the local chickweed season. It also doesn’t grow much farther south than central Florida. In northern climates Chickweed is a green of spring. It actually germinates under the snow so it can get a head start on other spring plants. Snow spits here every half century or so and the ground never freezes which is why we can forage 365 days a year. Chickweed is fairly easy to identify. Besides tasting like corn silk it has a stretchy inner core and one line of hair that runs along the stem switching sides at each pair of leaves. Don’t confuse Chickweed for a local cousin the edible, Drymaria cordata. To read more about chickweed click here.  Also coming on strong is Pellitory. To read about Pellitory again click here.

Foraging classes are held rain or shine. Photo by Nermina Krenata

Foraging Classes: It was a chilly start for the week with a foraging class in Port Charlotte that started out in the 40’s  but warmed up nicely over the morning. As you read about earlier several species were blooming out of season even fruiting. I have one schedule class this weekend and it’s in east Orlando at Blanchard Park, rain, shine or cold. 

Saturday, December 16th,  Blanchard Park, 10501 Jay Blanchard Trail, Orlando, FL 32817. 9 a.m. Meet by the tennis courts near the WMCA building.

Saturday, December 23, Colby-Alderman Park: 1099 Massachusetts Street, Cassadaga. Fla. 32706. 9 a.m.

The DVD set has 135 videos.

All of Green Deane’s videos available for free on You Tube. They do have ads on them so every time you watch a Green Deane video I get a quarter of one cent. Four views, one cent. Not exactly a large money-maker but it helps pays for this newsletter. If you want to see the videos without ads and some in slightly better quality you can order the DVD set. It is nine DVDs with 15 videos on each for a total of 135 videos.  Many people want their own copy of the videos or they have a slow service and its easier to order then to watch them on-line. The DVDs make a good gift for that forager you know especially on long, cold winter months. Individual DVDs can also be ordered or you can pick and choose. You can order them by clicking on the button on the top right hand side of this page (if your window is open wide enough.)  Or you can go here.

Green Deane Forum

Want to identify a plant? Looking for a foraging reference? Do you have a UFO, an Unidentified Flowering Object you want identified? On the Green Deane Forum we chat about foraging all year. And it’s not just about warm-weather plants or just North American flora. Many nations around the world share common weeds so there’s a lot to talk about. There’s also more than weeds. The reference section has information for foraging around the world. There are also articles on food preservation, and forgotten skills from making bows to fermenting food. One special section is “From the Frightening Mail Bag” where we learn from people who eat first then ask questions later. You can join the forum by clicking on “forum” in the menu.

Keynote Speakers at the Florida Herbal Conference Linda and Luke Black Elk.

It’s time to be thinking about two conferences in February, Earthskills in Hawthorn, and the Florida Herbal Conference near Lake Wales. I lead plant walks at both events. Earthskills is Feb 7-11 and the Florida Herbal Conference is Feb 23-25. While the former organizes later in the year the Florida Herbal Conference is already accepting registrations. It is usually sold out so register early. Because you read this EatTheWeeds newsletter you get a discount for the Florida Herbal Conference. If you register between now and January 31 using the code FHC2018_GREENDEANE you can get a 30% discount. Keynote speakers this year at the Florida Herbal Conference are Linda and Luke Black Elk from the Standing Rock Reservation. Linda (of the Catawba Nation) is an ethnobotanist specializing in teaching about culturally important plants and their uses as food and medicine. She is a lecturer at Sitting Bull College in Fort Yates, North Dakota. Luke Black Elk (Thítȟuŋwaŋ Lakota) is a storyteller, grassroots activist, and traditional spiritualist. He has conducted research in water restoration, sustainable building design, and food sovereignty, and hopes to use these techniques to encourage a more traditional way of life among his people. Luke has lived on the Cheyenne River Sioux Reservation his entire life, becoming deeply involved in cultural and community activities.

Most of us have been told eating apple seeds is dangerous. That is usually followed by “there was a man who ate a cup of apple seeds and died…”

Is that theoretically possible? Yes.  You’d have to eat 85 grams of apples seeds, about three ounces, or about 114 seeds, all at one time, all thoroughly chewed. That could, in theory, deliver a fatal dose of cyanide. That’s for a 150 pound person, a larger person could tolerate more, a child much less. Probably children should not eat any apple seeds. The way cyanide works is rather fascinating. It attaches to our red blood cells better than oxygen. So instead of oxygen being delivered throughout the body for use cyanide is. We essentially suffocate. But what about the guy who ate the cup of seeds? There’s bit of a problem with that.  In 1964 John Kingsbury, Phd., an expert on plant poisonings, particularly regarding farm animals, published Poisonous Plants of the United States and Canada, Prentice-Hall. He was the expert and his book became the book to reference. On page 365 Kingsbury wrote:

“Apple seeds are cyanogenetic. A man, who found apple seeds a delicacy, saved a cupful of them. Eating them at one time, he was killed by cyanide poisoning.”

Kingsbury’s inclusion of the incident in his book gave the story legitimacy and it has been quoted extensively ever since by professionals and amateurs alike. But from a journalistic point of view the story is full of what we called in the newsroom “holes.” Who ate the seeds, when, and where? Basic facts that add credibility. Professor that he was Kingsbury included where he got the story from in footnote 1335. That footnote reads: Reynard, G.B., and J.B.S. Norton in Poisonous Plants of Maryland in Relationship to Livestock. Maryland Agricultural Experimental Station, Technical Bulletin. A10, 1942. 312pp. So Kingsbury in 1964 is quoting a farm bulletin from 1942. What does that bulletin say? On page 276 of the now 75-year old bulletin Reynard and Norton write about prussic acid harming livestock. (Amygdalin is essentially a sugar and cyanide molecule which when digested releases hydrogen cyanide which used to be called prussic acid.) They note in the last paragraph, above right:

“Apple seeds are mentioned, not as having caused stock-poisoning, but because of the fact that one instance was recorded from personal inquiry in which an adult man was killed following eating a cup of these seeds at one time. The seeds had been saved up, apparently thought to be a delicacy in small amounts and upon being eaten developed enough of the deadly prussic acid to cause this tragic death. The instance is recorded here as a caution to others who might attempt to eat more than a few of these seeds at any one time. Previous investigators have reported that apple seeds contain appreciable amounts of amygdalin from which prussic acid is developed, but actual reports of poisoning are rare.”

Florida Tasselflower is long-term toxic to humans and very toxic for horses.

Livestock poisonings from prussic acid are “rare.” What of  humans?  A 130-year search of the New York Times by this writer produced 437 stories involving prussic acid. Those included suicides, murders and a few accidental medicinal deaths. None by an apple seed overdose. We are left with no who, no where, and no when as well as a  “recorded from personal inquiry…”  and “apparently.” Read someone told them it had happened. Their reference is as weak as Kingsbury’s. Without a name, a time and place it is not much better than an urban legend. It could have happened, or it just might be a story.  More so, man has been eating apples for some 6,000 years. One would have thought in that amount of time it would have become common knowledge that you don’t eat a lot of apple seeds in one sitting. Also during the days of Johnny Appleseed everyone was making cider and there were millions of seeds available annually for decades if not centuries. One wouldn’t have to save them up at all. Getting rid of apple seeds was a problem, not getting enough of them. Also they dry out very quickly so if you saved only a few at at time by the time you had a cup that way the earlier seeds would not be edible. And with all those millions of seeds around and hungry people why only one report of an apple seed over dose?

We can’t say the story is not true, but we can call it doubtful. Click here to read about Wild Apples.

Dr. James Duke 1929-2017

This week sadly saw the passing of Dr. James Duke, 88, botanist, author, friend of herbalist and forager alike. He had been in waning health. When you needed an authoritative source to back up your plant claim it was often one of  Dr. Duke’s publication that came to the rescue. I have several of his books.  Interestingly Duke came into his career in botany in the most unusual of ways. He wrote that when he was around age seven he was in the woods and had to go to the bathroom. Unknowingly he wiped himself with poison ivy and got an unforgettable rash. He decided right then that he needed to know more about plants. That led to an illustrious career with the U.S. Department of Agriculture specializing in medicinal plants. He was particularly interested in the medical potential of plants used  in neotropical ethnobotany. A more extensive article about him is here. 

This is issue 282.
