Worth knowing

  • Once on Mallorca, Menorca and Cabrera, the Balearic peony is now confined to mountains in northern Mallorca. Feral goats, flower picking and digging for gardens have shrunk its range. Wikipedia: Paeonia cambessedesii

Protocol

DerivedN. C. Deno, 1993

Difficulty Moderate Rated by us, not by the source.

  1. Warm moist stratification

    Duration: 90 daysTemperature: 70°F 21°C

  2. Cold moist stratification

    Temperature: 40°F 4°C

    Two of four. Three more followed 2-3 years on.

  3. Warm moist stratification

    Temperature: 70°F 21°C

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

about 3 months from start to step 3. Germination happens during step 3, in 49 days.

50% germination in 35–49 days.

Two seeds of four -- and three more came up two to three years later, at 40.

This source doesn't state how long step 2 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. P. cambessedi germ; 70-40(2/4 in 5-7 w). Three seeds germ. 2-3 .y later at 40.
