During the field trips that I’ve
conducted for the past 35 years, I show participants how to identify common
edible plants, and we make a simple meal on nearly every field trip. Some of these most common wild edibles can
be initially learned after a few hours – or days -- of focussed study, and
practice. Once you take the time to
learn the key features of these plants, and after you’ve watched them
throughout a growing season, you’ll know them whenever and wherever you see
them. One by one by one is how I’ve
learned about wild edibles. And though
there is no shortcut to this learning, you can accelerate your comprehension
and mastery of ethnobotany if you also learn about plant families.
Some
examples of common plant families include the rose family, sunflower family,
goosefoot family, mustard family, mint family, and so on. Botanists group plants together by their
similar floral, fruit, and leaf characteristics, with the floral
characteristics being the most important.
You’ll note that many of the traits of plants (poisons, alkaloids,
medicines, foods, etc.) often run in families.
There are obviously many exception s to this, but plants that are related by floral characteristics often share
other traits as well.
For example, one of the largest plant families is
the Sunflower Family (Asteraceae). This
is a huge botanical family, consisting of about 21,000 species of plants,
divided into approximately 1,300 genera.
It’s such a large group that botanists have sub-divided it into groups
or tribes. Depending on whether the
particular botanist is a “splitter” or a “grouper,” you’ll find from 11 to 13
groups in the Sunflower Family.
Today, let’s focus on just one of those groups or
tribes within the Sunflower Family.
Here in California, I use The Jepson Manual of the Higher Plants of
California, published in 1993. [There
is some such reference used by botanists for every part of the U.S. and much of
the world. It would enhance your
learning to obtain the official book of flora for wherever you live.]
When I was in high school and studying from the 1925
version of Jepson’s manual, the Sunflower Family was divided into groups called
tribes. One of these tribes used to be called the Chicory Tribe, though in the latest edition it is simply referred
to as “Group 7.” According to Dr. Leonid Enari, the former chief botanist with
the L.A. County Arboretum, the Chicory Tribe of the Sunflower Family consists
of no toxic plants, and all that are palatable can be eaten.
THE CHICORY TRIBE
If you already know how to recognize a dandelion, or
a chicory plant, you’re familiar with the Chicory Tribe.
As I reviewed the genera of the Chicory Tribe, many
consisted of only one species of a plant not commonly known. Where I live, there are as many natives as
there are exotics.
Perhaps the best general statement that can be made
about the Chicory Tribe is that none are known to be poisonous. I have eaten many of them, raw and cooked,
including the ragweeds (Agoseris sp.), whose pollen is often responsible for
allergies. Tasting a bit like medicine,
it is nevertheless palatable.
I have also eaten the malacothrix greens on numerous
occasions. These western natives are
called prickly lettuce and desert dandelion, among other names, suggesting they
have been eaten. As they mature they are incredibly bitter, and therefore I only
regard the very young growth as palatable.
Another member of this Tribe, Picris, has only one
species, an introduced plant known as bristly ox-tongue. The leaf actually looks like a big tongue,
covered with soft spines. Though
edible, it is not palatable when raw, and even cooking does not entirely reduce
the stickers. I would only use it for food if I had nothing else available.
Fortunately, most parts of North America have many
of the common members of the Chicory Tribe, such as chicory, wild lettuce
(Lactuca), sow thistle, dandelion, and salsify, all exotics.
If you’re already familiar with a
dandelion, then you’re well on your way to learning to recognize this entire
Tribe. Note that the flowers of these
are composite, that is, each flower is composed of a tight group of individual flowers. What appears to be a single dandelion flower
is in reality up to several hundred flowers clustered together.
RECOGNIZING THE CHICORY TRIBE
Here are some of the key characteristics which help you recognize the Chicory Tribe:
First, there is the composite “dandelion-like”
flower. It doesn’t have to be yellow, as it may appear white, orange, blue,
etc.
Also, the tip of each “petal” is 5-lobed. You might have to look with a magnifying
glass to see this.
In addition, there is generally a milky sap when you
break the leaf or stem.
I recommend that you begin by studying the
dandelion, and then attempt to identify other members of this tribe by these
guidelines. However, don’t eat any of
these until you have positively ascertained that it’s actually in the Chicory
Tribe. Even then, many of the members of this Tribe are very bitter, and some
are fibrous. Even though none are
toxic, that doesn’t mean that all are readily palatable.
In other words, don’t eat anything until you’re
positive, and even then go slowly!
The leaves of dandelion are
incredibly nutritious, but also bitter.
Cooking can reduce the bitterness.
Young sow thistle, lettuce, and chicory leaves can all be used raw; as they mature and get bitter, they are best
cooked like spinach, or added to soups, stews, and other cooked dishes.
The dandelion, sow thistle, chicory, and salsify all
have edible roots. All should be cooked
to tenderize. Sow thistle roots tend to
be the smallest, but the size of all of these will depend on the richness of
the soil they’re growing in.
These roots – primarily chicory and dandelion --
also have a long history of being dried, roasted, ground, and used as a
caffein-free coffee substitute.
