While native peoples, and
then early settlers, foraged in the wilds for edible plants, you can forage in
your garden for edible flowers and other plant parts. But do so safely.
gathering in your garden, be sure you know your plants. Within the same genus,
some may be edible, others toxic. For example, the boneset genus (Eupatorium)
contains the species or common wild plant Joe-pye weed (purpureum)
which, when dried, has a vanilla odor and makes a pleasant tea. White snakeroot, another species (rugosum)
within the genus, is poisonous. And, of
course, you should never eat any plants treated with harmful pesticides.
plants can be safely consumed in small amounts or through careful preparation.
Leaves of tansy (Tanacetum) have been used in omelettes, yet in high
doses this plant is toxic. Shoots and leaves of the butterfly weed (Asclepias)
are eaten by Native Americans, who know to boil them before eating as parts of
this plant can be toxic unless prepared properly.
example of a potentially toxic plant is the German iris. Its roots can be
chewed as a breath freshener, but in high doses may lead to vomiting.
fiddleheads from the ostrich fern (Matteucia), a popular springtime
treat in northern areas, may cause an upset stomach if not boiled for at least
15 minutes. These are also popular in Japan where they are called
"kusasotetsu" when boiled and fried in butter, or slowly cooked in
centuries yucca leaves served as a source of fiber for ropes, bags, and
clothing for Native Americans,
with the terminal thorn of leaves serving as a handy needle. They ground and
used the roots for soap and as a shampoo, as the roots are rich in saponin.
Roots of the native meadowsweets (Filipendula) also make a good
meadowsweet has many other uses. Tubers of one species (vulgaris, syn. hexapetala) were consumed in Europe in times
of famine. The fragrant flowers of another species (ulmaria) are still
used to flavor desserts, especially ice cream, and drinks such as teas. The
flowering tops also can be used to dye wool black, or when used with alum, a
greenish-yellow. The dry plant contains salicylic acid, the source of the
active ingredient in aspirin, and has been used medicinally in Europe.
early spring flowers of primroses have a delicate sweet smell and can be added
to fruit salads or made into a mousse and other desserts. Leaves of the
primrose can be eaten raw in salads or cooked. They're a good source of vitamin
C and minerals.
people don't realize that the daylily (Hemerocallis) also has many
edible parts. I like the slightly sweet taste of the raw, open flowers. Or you
can place an open flower in a fluted dessert cup, add a scoop of ice cream, and
drizzle chocolate on top for a really unique treat!
roots and shoots of the daylily are tasty raw. The flower buds can also be
eaten raw or slightly steamed, pickled, or made into delicious omelettes. Or
add the wilted flowers to soups or stews.
common perennial, the lily, is used as a food in its native Asia. Boiled and
then dried, the lily "bulb" is a key ingredient in the Japanese
"namono" eaten during the Japanese New Year. Pollen of this perennial is nutritious and
pleasant tasting and is often eaten sprinkled over food.
of lady’s mantle (Alchemilla) are
astringent, and sometimes added raw to salads.
It has been used
medicinally since ancient times, the drops of water that gather on leaves used
in alchemy, hence the scientific name.
of violets (Viola) can be added fresh
to salads, or crystallized into candies.
The leaves are nutritious, containing Vitamins A and C and healthful
minerals. Add violet leaves to salads,
cook as a vegetable, or use for soups.
grow from tubers which aren’t hardy in northern climates and have to be dug
over winter and stored in a non-freezing place.
These tuberous roots have been eaten in parts of Mexico, dating back to
the time of the Aztecs. They are sweet,
similar to a Jerusalem artichoke. The
sweetness is from the sugar inulin that diabetics can easily assimilate. Dahlia flowers make nice additions to salads.
