Silphium perfoliatum

FULL SUN (but I have mine in morning shade/afternoon sun)

A native of the tallgrass prairie, this perennial giant sports wonderfully cheerful yellow daisy-like flowers (BIRDS LOVE THEM!) on long, stout stalks reaching up to 5' in height!
Even more interesting than the flowers are the coarse leaves from which this species gets its name. Borne opposite one another on the stem, the large leaves fuse together at their bases to form a "cup" of sorts. Even on the hottest summer days one can usually find water from the morning dew collected within these miniature green receptacles.
