Difficulty High Rated by us, not by the source.

Start around October 4, 2026 for a May 3 last frost.

  1. Warm moist stratification

    Duration: 90 daysTemperature: 70°F 21°C Light: dark

    14 germinated in this phase.

  2. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

Bupleurum (Apiaceae). B; aureum germ. best in. 40(99% in 3rd w) or outdoor treatment (96% in March) and poorer in 70(25% in 1-11 w)-40(18% in 2-5 w)-70. This last sample was treated with GA-3 after 5 w at 70 whereupon the remaining 57% germ. in 1-3 w. It is likely that GA-3 treatment would have led to 100% .germination immediately at 70. Light had no effect. Seeds placed outdoors March 1 germ. 96% in April, a result of the low T. B. spinosum germ. 70D(14% in 8-11 w)-40(28% in 3d w) and 40-70-40(1/7).
