Silphium perfoliatum

Cup Plant
$11.95
A must for attracting wildlife, this tall member of the Aster family, grows 4-8' tall bearing branches of 3" yellow daisies from mid summer to early fall. Commonly called Cup Plant because the middle and upper leaves lack petioles, and the leaves envelope the stem to form a little reservoir which holds water to nourish birds and butterflies. Especially attractive are the seed heads that follow in fall, resembling, in my opinion, little green ranunculus. This Silphium is rather easy to grown but loves a wet soil that has a neutral or slightly alkaline pH.
