This source reports two treatments. Both are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty Low Rated by us, not by the source.

Start around March 1, 2027 for a May 3 last frost.

  1. Gibberellic acid soak

  2. Sow and cover

    Temperature: 70°F 21°C

No stated waiting before sowing. Then 35 days to germinate.

76% germination in 7–35 days.

Aquilegia (Ranunculaceae). Three treatments gave germination, and all other treatments failed. The three were (a) treatment of fresh or DS seed with GA-3 at 70, (b) sowing of OS seed at 70, and (c) outdoor treatment. All three of the treatments were used In only a few of the species so that it is not certain that all three will work with every species. Stewart and Presley (ref. 9) were the first to report that GA-3 was valuable in stimulating the germination of A. skinned germ. 30% in the 5th w at 70. A. sp:(Darwas) germ. 70(24% in 1-4w) and 70 GA-3(76% in 1-5 w).

Start around March 8, 2027 for a May 3 last frost.

  1. Sow and cover
