Epimedium acuminatum - Barrenwort

Little evergreen undershrubs, or deciduous perennials, with delicate flowers. These very beautiful shade plants can be grown in a bed, or a large shaded rockery, preferably along a path to fully enjoy their great beauty. They all withstand temperatures as low as -12°C (10.4°F), -13°C (8.6°F) without any protection. Western species are highly cold-resistant and accept difficult conditions such as living in dense shade under trees, in very dry soil or even in moist clay soil. Asian species prefer a soil that remains wet to moist in summer, well-drained, rich in humus, without limestone and also tolerate dense shade. They all grow relatively slowly, but live for many years without any particular care.
