Asarum
Wild
Ginger
The
wild gingers are low growing woodland plants with large showy leaves
that spread by underground rhizomes. Most species are evergreen
although even these can lose leaves in extreme winter cold. Their
unusual Dutchman's Pipe flowers are often at soil level and can be hidden from
view by the large leaves. They are most commonly found in the moist, humus rich soils
of sloping woodland habitats in North America, Asia and Europe.
In
cultivation, wild gingers thrive in woodland gardens in light shade. They are generally slow to moderate growers but can reward
the patient gardener with a lovely clump. All types can also
be grown successfully in containers where their foliage can be appreciated
and their unique flowers more easily viewed. Slugs can be a problem
in some gardens but we have been able to control them successfully with
the non-toxic iron phosphate formulation found in products such as Sluggo.
The common
name wild ginger refers to the fact that the stems and roots of many
species have a spicy odor similar to that of culinary ginger.
Culinary ginger is not, however, an Asarum. Culinary ginger is
in the Zingiberaceae or true ginger family while wild gingers are members
of the Aristolochiaceae or pipe vine family. Various species of
Asarum are used medicinally.
