Cup Plant (Silphium perfoliatum) - 6 Pack of 1 gallon Pots
A magnificent North American native perennial that towers up to 10 feet tall in the garden, the Cup Plant, Silphium perfoliatum, is a jolly yellow giant perfect for dwelling at the back of the border, against a tall fence or to fill corners in the garden. It gets its name from the water-holding "cup" that is formed by adjoining large and stout leaves on either side of the square stem. Birds, butterflies, insects and frogs will frequent the cups to get a drink. The large leaves provide a lush almost tropical look in the garden that all serve as a cover for birds. From mid to late summer, large and showy 3 to 4 inch diameter bright yellow daisies are produced in abundance attracting butterflies, hummingbirds and beneficial pollinators. Birds, especially goldfinches, feast on the seeds. Recipient of the Royal Horticultural Society’s Award of Garden Merit for reliable performance in the garden, the Cup Plant is very easy to grow and maintenance-free almost anywhere in the U.S. in USDA Zones 3a-9b.
