Butterfly Flower
Asclepias tuberosa
Family Asclepiadaceous
Butterfly weed is a must for the perennial gardener who wishes to attract butterflies to the
perennial garden. The variety shown here is a cultivar named Gay Butterflies. The wild variety is
usually orange, though other flower colors may be found.
Asclepias tuberosa grows to about thirty six inches tall in my southern Indiana garden and blooms
from about mid June until mid to late July. The flowers make good cut flowers for the vase. If you
cut the flowers from the main stem, it will encourage the plant to produce more flowers further down
the stem later on.
Butterfly Weed is slow to appear in the spring, so have patience with it, it will eventually emerge
and reward you with its showy blooms. It is hardy to USDA Zone 4 and likes dry soil. This is a native
American perennial and can the wild flower be found in meadows, fence rows and other areas.
Butterflies are attracted to the flower in great numbers, swallowtails, monarchs and others feeding
on the nectar. The leaves and developing seed pods are food for the caterpillars, as the adults will
lay their eggs under the leaves. I usually leave the plants in place, even though after bloom they
become unattractive and rather messy with the silken seed pods developing because one or two
generations of caterpillars feed on the plants until late in the summer.
Propagate Asclepias tuberosa by seed. In the spring root cuttings may be taken. If you have a named
variety root cuttings are necessary, as seedlings will be highly variable. Division is difficult as
the mature plant develops a large taproot.
Butterfly weed (Asclepias tuberosa) is an excellent addition to the perennial garden. It is an excellent
butterfly attractant and the flowers are colorful.
