Seed Pack - Rosinweed (Silphium integrifolium)

This listing is for one packet of Rosinweed (Silphium integrifolium) seeds. Each packet contains roughly 75 seeds. For best germination of native species, remember to scatter seeds October-January!

A.k.a. rosin weed. A hardy plant that matures faster than other Silphium (such as prairie dock and compass plant) and may tolerate drought even better. Flowers are just as showy as its cousins, with the bonus that rosinweed generally does not need to be staked despite its height. May form colonies, but is not particularly aggressive.
