Impressive perennial that’s not easy to miss especially when the yellow daisy-type flowers appear in August on the tall flowering stems which arise from a clump of large, long stalked leaves.
Extremely drought-resistant and long-lived, it also attracts a lot of pollinators, including hummingbirds; also the seeds are on the goldfinches’ menu!
Great as a specimen plant in the flower bed. Tony Avent from PDN sums it up best: “Silphium terebinthinaceum is one of those tropical-looking perennials that would be in every plant collector’s garden if it were native to Asia. Unfortunately, it calls the US home, where it grows in prairies from Canada south to Mississippi.”
Germination: sown in late fall outdoors, or in spring to late spring but in the latter case it requires 3 months of cold-moist stratification.
