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 30, 2027 for a May 3 last frost.

  1. Sow and cover

    Temperature: 70°F 21°C

No stated waiting before sowing. Then 6 days to germinate.

100% germination in 3–6 days.

Fresh seed or six months' dry storage at 70 or 40 -- it made no difference.

Gaillardia (Asteraceae). G. aristata germ. 70(100% in 3-6 d) and 40(60% in 2-8 w)-70(40% in 1-3 d) using either fresh seed or seed DS -6 m at 70 or 40.
Seed Germination Theory and Practice, 2nd ed., Ch. 20, Gaillardia. Quoted exactly. Every value on this card comes from this record, except the difficulty rating, which is ours; the step names come from a fixed list.

Protocol 2

DerivedN. C. Deno, 1993

Difficulty Low Rated by us, not by the source.

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

  1. Cold moist stratification

    Temperature: 40°F 4°C

    60% germinated at 40 itself, in 2-8 weeks.

  2. Warm moist stratification

    Temperature: 70°F 21°C

    A further 40% in 1-3 days after the move.

No stated waiting before sowing. Then 56 days to germinate.

60% germination in 14–56 days.

Slower and no better than sowing straight at 70.

This source doesn't state how long.
