Silphium laciniatum
$12.95
One of the belles of the Silphium tribe, this rare Southeast U.S. endemic bears 2-inch-wide, pastel-yellow "sunflowers" that are of a softer, more blendable hue than those of most other yellow-flowered summer-blooming plants. They are carried on 4-foot stems in late summer, above clumps of silver-furred basal leaves. Zone 5. Propagated from seed. Deep 3.5-inch pots.
