Worth knowing

  • Linnaeus described it in 1771 from a Siberian plant. It almost always carries just one fully developed flower per stem. Wikipedia: Paeonia anomala

Protocol

DerivedN. C. Deno, 1993

Difficulty Moderate Rated by us, not by the source.

  1. Warm moist stratification

    Duration: 60 daysTemperature: 70°F 21°C

    The radicle and its branching root system form here. This is what Deno counts as germination.

  2. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

  3. Warm moist stratification

    Temperature: 70°F 21°C

    The single true leaf forms only now. Germination is hypogeal.

about 5 months from start to step 3. Germination happens during step 3.

Deno lists it as germinating at 70 like P. officinalis, and gives no figures for it.

This source doesn't state how long step 3 lasts.

Paeonea (Ranunculacèae). Nicking the seeds of P. officinalis and P. suffruticosa was reported to give some promotion to germination in the first edition, but this has not been confirmed in later and more extensive experiments. P:anomala, emodi, lutea, mlkosewetschii, obovata, and vernalis germ. at 70. similar to P.officinalis. Germination consists of forming a radicle and a branching root system. This requires about 2 m after which the seedlings are given 3 m at 40. On shifting back to 70 the true leaf forms (hypogeal). Germination was hypogeal in all but P. brownii,tand all germ. at 70 except P. broteri and P. brownii. These germ. at 40. Treatment with GA-3 gave a small increase in rate of germination in P. officinalis and P. suffruticosa.
