Difficulty High Rated by us, not by the source.

Start around July 16, 2027 for a May 3 last frost. Too late for spring 2027 — that needed starting on July 15, 2026.

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

  2. Warm moist stratification

    Duration: 90 daysTemperature: 70°F 21°C

about 6 months from start to sowing. Then 84 days to germinate.

27% germination in 70–84 days.

Dentaria (Brassicaceae). D. laciniata germ. best when the seeds were treated with GA-3 and started at either 70 or 40. The data were 40-70(27% in 10-12 w) and 70-40(20% in 6-12 w). The seedlings from the GA-3 treatment appeared normal but more time is needed to be sure that healthy plants will develop. Germination of D. laciniata is most unusual for Brassicaceae. Not only is DS not tolerated, but germination is hypogeal with the radicle growing to a length of a cm. in one day and producing branching roots before the true leaf forms a few weeks later.
