Bearsfoot, also known as Hairy Leafcup, is a perennial wildflower native to the eastern and central United States where it can often be found growing in meadows, at the edges of woodlands, and along the banks of river and streams.
The plant, whose large leaves as said to resemble a bear's footprint, grows to around 7 feet in height and produces small yellows flowers that bloom from July through September.
Historically used in traditional medicine to treat swelling and inflammation, as well as in tonics to (allegedly) promote hair growth.

Growth Chart
Hardiness Zones: 5 to 9 Light Requirement: Full to partial sun Soil Type: Sandy, loamy, clay Sow Depth: 1/8 inch Plant Spacing: 12 to 36 inches Germination Note: Cold stratification required Stratification Time: 60 days Bloom Time: July through September Growing Tips
Before sowing, scarify seeds by pouring hot water over them and allowing the seeds to soak for 24 hours.
Direct sow in late fall by planting the seeds just below the soil's surface. For spring planting, after scarification mix the seeds with moist sand and store in the refrigerator for 60 days (cold stratification) before sowing.
A Note on Cold Stratification
These seeds require cold, moist stratification. To naturally stratify the seeds, plant outdoors late fall on a weed-free site and allow seeds to overwinter.
To artificially stratify the seeds, place the seeds and a moist medium (such as a damp paper towel, coffee filter, sand, or vermiculite) in a labeled, sealed plastic bag and store in a refrigerator (33-40°F) for the amount of time noted on the growth chart before sowing.
