Germination Information: I recommend these only for gardeners who have experience with seeds that require a chilling period to initiate germination. (Handling Seeds that Need Chilling)

The easiest approach is to surface-sow the seeds in late fall to midwinter and leave the pot outdoors for a natural chilling period. I started my plants by winter-sowing seeds on January 15; the first seedling appeared on May 30. Your experience may vary.

If you sow after January, give the pot an artificial chilling period of about 3 months.

Note that this information will not appear on the seed packet you receive.

Description

Northern horsebalm (Collinsonia canadensis), also known as richweed or stoneroot, blooms in mid or late summer to early fall, with branching, open clusters of small, yellow flowers over the large, toothed, rich green leaves. Both the flowers and foliage of this mint-family member have a pleasing lemony fragrance. It spreads moderately by rhizomes to form clumps that are generally reach 3 to 4 feet tall and wide. Native to the eastern half of the US. These seeds are from plants growing here in Bucks County, PA. Partial shade; average to moist soil. Perennial; Zones 4 to 8.
