Silphium integrifolium, known as rosinweed, shares some similarities to last month’s featured seed, prairie dock. In fact, prairie dock is often referred to as prairie rosinweed. Both of these perennial plants feature bright, yellow flowers. When cut or broken, their stems produce a resinous sap.  

However, you shouldn’t expect traditional rosinweed, also known as whole-leaf rosinweedto grow as tall as prairie dock. Typically, rosinweed stands 2-3 feet tall, though it can reach heights over 6 feetIt can be found from Wyoming all the way to the east coast. The leaves of rosinweed generally grow in symmetrical pairs, scaling up most of the stem. The plant itself is known to tolerate droughts well. 

Native Americans would use rosinweed for a number of purposes including pain treatment. Currently, the Land Institute is working to utilize rosinweed as an oilseed crop. 

Rosinweed in CRP 

Like other members of the silphium genus, rosinweed can be a great addition to CRP establishment. Its yellow flowers are known to attract a number of pollinators including bees and butterflies. As with compass plant, gall wasps will inject their eggs into rosinweed stems and create a gall. Adult wasps will then emerge the following the season. 

White-tailed deer are known to use rosinweed as a food source. 

Rosinweed competes well against most prairie grasses and forbs. It typically starts blooming mid-summer, with its blooming period lasting for 1-2 months. When including rosinweed in your CRP mix, it’s important to balance it out with at least two other colors during its respective bloom period. Additionally, you want at least 3 colors for the other two blooming periods.
