American Bugbane (Summer Cohosh)

American Bugbane - Cimicifuga americana.
Homeland - the eastern regions of North America. Perennial herbaceous plant 90-150 cm tall. Leaves are dull, dark green.
The flowers are very small, silvery-white-cream, collected in very beautiful long and narrow racemose cylindrical inflorescences.
Blooms in July-August. Fruiting. In culture since 1822.

A prominent specialist in seed propagation, Norman Deno, in his three-volume "Seed germination. Theory and practice" writes that, sown fresh, black cohosh seeds tend to rot. He assures that 100% germination was observed after six months of dry storage during stratification: 3 months at a temperature of +20 and 3 months at +4 °C. Approximately this period is required for the development of the embryo. Many experts adhere to a similar opinion, however, the temperature of dry storage of seeds and the terms vary significantly (from one and a half to eight months). Since the plant produces quite a lot of seeds (if you can only get them), it is worth trying various sowing options. Plants obtained from seeds bloom in the second or fourth year. They grow in one place for 15-20 years.
