Seed ripensearly October

Gracefully arching stems with bluish green foliage and green flowers through summer, turning a nice tan in autumn - nice for dried arrangements. We grow them in clusters, making a fountain of foliage and seedheads. They make a bit of a nuisance of themselves with their aggressive self-seeding (and somewhat difficult to extract root mass), but we wouldn't want to be without them. The species is native to a large swath of the eastern United States.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.

Seed-starting details for this plant

  1. Seed wild-collected '98. Cellpack 70F. No germination inside - moved to outside greenhouse after a few weeks, and germination started about a month after sowing

Every year since then, they've self-sowed in my garden - enough for a nice supply, not annoyingly so.
