This plant is incredibly easy to propagate, as it spreads by rhizome. One plant, if mulched well with high-nitrogen material like fresh hay, will produce a small, healthy clump in its first summer. It wants to spread by both rhizome and seed. Sochan does well in full sun or partial shade; it will survive moderate shade. It likes rich soil of a medium texture—not too coarse or too much clay. Towering 6-8 feet tall with gorgeous yellow flowers in mid to late summer, this plant is often grown for its beauty alone, but the young greens and shoots are also a good vegetable, and the seeds attract many songbirds. Sold as a rhizome section with one or more buds.
