Silphium laciniatum
“Compass Plant”

GOT CLAY? This big, refined Sunflower-looking native from the Midwest is well known in those parts for its ability to thrive in clay. Towering, 5’-8’, branching stalks bear up to 100 large (4”-5”) “sunflowers” at one time. The deeply lobed foliage is very attractive & turns to face the sun all day. Long lived, it flourishes in the garden & with its very long taproot, tolerates drought extremely well. Good cut flower, many medicinal uses - bird & butterfly magnet! Blooms June - September.
