Silphium,

Asteraceae, cup plant, prairie dock

Giant plants from the tall grass prairie. This is an almost extinct plant community in the American Midwest that consisted of grasses and perennials that could reach up to 3 or 4 m in height. The cup plant has large foliage and delicate, fresh yellow sunflowers.

Silphium laciniatum

S. laciniatum

300 8-9

Arching stalks, with long, deeply cut, lyreshaped foliage. Flowers arranged on lax spikes, like a hollyhock.

S. terebinthinaceum

300 7-9

Forms a rosette of huge (up to 60 cm), corrugated, lightly dentate foliage from which long, almost leafless, lax-branched flowering stems arise. The foliage turns almost black in late autumn and is a lovely sight in winter. Can self-seed aggressively.
