Why the Audubon® Rosin Weed?

At four to six feet tall, Rosin Weed is the smallest of the Silphiums, a group of Sunflower lookalikes that includes Compass Plant and Prairie Dock. Nevertheless, it is a substantial plant. This sturdy, hardy Spirit captures the rugged beauty of the tallgrass prairie, where it was once native, and it will lend a touch of wildness to your backyard beds and borders as well. Your local wildlife will appreciate Rosin Weed, too! Monarchs, Swallowtails, and Painted Lady Butterflies will love the nectar in the yellow summer Daisy flowers. In fall and winter, Goldfinches will enjoy the seeds.

Rosin Weed is native to the midsection of our country, from Nebraska to Michigan in the North and Texas to Alabama in the South. An inhabitant of the majestic tallgrass prairie that is mostly gone now, it once stood shoulder-to-shoulder with Big Bluestem and other grasses and prairie wildflowers. Rosin Weed was well-adapted to life on the prairie, with deep roots that could delve down 10 or 12 feet. When fire struck, it would simply regenerate itself from the massive rootstock. Drought was no problem, either, once the plant was established.

How to use in the landscape?

Rosin Weed gets its name from the sticky substance found inside the stems. Native American kids used to scrape off this rosin and use it as chewing gum. You can try it, too—just don’t expect it to taste like Juicy Fruit! (It tastes more like Pine Tree.

What is the definition of Native?

“In the United States, a native plant is defined as one that was naturally found in a particular area before European colonization. Native plants are the foundation of a region’s biodiversity, providing essential food sources and shelter for birds, especially those threatened by the changing climate. Since native plants are adapted to local precipitation and soil conditions, they generally require less upkeep, therefore helping the environment and saving you time, water, and money.” – The National Audubon Society

How To Plant

Rosin Weed prefers deep, loamy soil that never gets extremely wet or extremely dry. It wants full sun. This species is stockier and stronger than other Silphiums, so it will not need staking. It is unlikely to flop. It’s also faster-growing than other Silphiums, though it does still take a few years to bulk up. This plant forms several long, deep roots over time and will become difficult to transplant. Choose its position carefully and then leave it be. Maintenance is simple for Rosin Weed. Leave the seeds for winter-resident birds, then cut the whole plant down in early spring.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer, start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late fall. Continue this for the first three years to get your plant well established.
