Some are very tolerant of dry shade (not all). With the ongoing discovery of many
new species, mostly from the mountains of SW China, and a proliferation of nurserymen
and breeders selecting and naming new cultivars, there is an ever increasing range
of new forms to choose from. They can be deciduous or evergreen, clumping or spreading,
in an ever increasing range of colors. There is something for everyone.
Epimediums will not provide the blast of color that some expect in their garden.
Rather they have a delicate wildflower charm that those with a taste for the subtle
and finer points of life are sure to appreciate. This, along with ease of culture,
are making epimediums one of the hottest new groups of plants around. Warning -
they can be addictive!
Epimediums are all native to temperate woodland situations. There are species in
Europe, Japan, Korea, the Caucasus region between the Caspian Sea and the Black Sea,
but with the greatest number and diversity coming from China, mostly from the mountains
of Sichuan and Yunnan. New species are still being discovered.
CULTURE: In the garden they thrive in well drained, but moisture retentive soil.
They do not tolerate wet soil. They are best in light or filtered shade. If the
shade is too deep, they will grow, but will have few blooms. They can take some sun,
but too much sun and heat will scorch the leaves. While it is true that some are
very tolerant of dry shade, and are excellent as a groundcover under shallow rooted
trees, this is not true with all species, especially the newer Chinese species. If
you are going to cut back all the foliage for a better floral display, it is best
to wait until early spring, but be careful that you do this before the new growth
has emerged, or you risk cutting off the new with the old.
HARDINESS: Unless indicated otherwise, they have all been proven hardy to zone 5b.
PROPAGATION: Dividing is best done in early spring or late summer into early fall,
while they are putting out new roots. They can also be grown from seed. They seem
to be self sterile, so if seed is forming, it will most likely be a hybrid. The
seed pods and the seed are still green when they fall. Then the ants carry the seeds
away, so if you want to collect seed, watch it carefully when the pods start swelling.

Epimediums are some of the most charming, easy going plants that you can plant in
shade. They bloom in spring, with small flowers, (2” across is considered large)
often with long spurs (again, ‘long’ being a relative term), that dangle gracefully
from upright or arching stems. It is not the size of the flowers that matter here,
but rather the lovely effect of sometimes up to a hundred flowers on a stem less
than 2‘ long, over tidy, dense, weed smothering clumps of foliage that are often
dramatically mottled with bronzy red markings in spring and again in fall.
