This source reports two treatments. Both are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty Moderate Rated by us, not by the source.

Start around January 11, 2027 for a May 3 last frost.

  1. Cold moist stratification

    Temperature: 40°F 4°C

    48%, at 10-12 weeks -- it germinates in the cold.

  2. Warm moist stratification

    Temperature: 70°F 21°C

    A further 36%, over 2-16 days.

No stated waiting before sowing. Then 84 days to germinate.

48% germination in 70–84 days.

Nearly half comes up in the cold itself, and a third more again after the move.

This source doesn't state how long.

Talinum (Portulacaceae). Sowing at 40was better than sowing at 70. T. okanoganense germ. 40(48% in 10-12 w)-70(36% in 2-16 d) and none at 70..

Protocol 2

DerivedN. C. Deno, 1993
  1. Sow and cover

    Temperature: 70°F 21°C

    Nothing.

No stated waiting before sowing.

0% germination.

Nothing at all. Deno's rule for the genus holds here: sowing at 40 beats sowing at 70.
