Compass Plant (Silphium laciniatum), packet of 20 seeds
Family: Aster (Asteracea)
Hardy to Zones 3 to 8
(Pilot Weed, Rosin Weed) Towering herbaceous perennial with deep delving roots. Native to the American prairies. The large, handsomely and characteristically lobed leaves are very impressive, designed by nature to rise up through and push away prairie grasses. The stems are heavy, thick, hairy and green, glistening with fragrant and bitter gum. Traditional usage (Native American, TWM): expectorant, chronic cough. Plant prefers open grasslands or regular garden culture. Give full sun, moist soil. During dormancy, burn off over the crown every few years (they won’t mind, they are stimulated and cleaned by the fire and nourished by the ash). Sow in early spring or spring. Some cold conditioning is desirable to get complete germination, but the seeds usually respond sufficiently to standard greenhouse technique. They can be nicely direct-seeded in fertile soil in the early spring, as the seedlings are quite large and can compete to some extent out there in the big world. Flowers to 9 feet, space plants at least 3 feet apart.

Admin Richo Cech –
A few wild ones may still survive in cemetaries or forgotten corners of vestigial prairie, but mainly the ones you see nowadays have been planted by prairie restoration folks. I find them indispensable in the herb garden, due to their majesticness.

Can you Fall plant these in Zone 3?
Richo Cech –
hi JD, This depends on your facilities, but if you have a good way to plant and tag and mulch the seeds, then yes, fall-sowing is very productive on these. Richo
