Deno’s Garden

Anemonastrum tetrasepalum

Genus Anemonastrum

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 July 10, 2027 for a May 3 last frost. Too late for spring 2027 — that needed starting on July 9, 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 90 days to germinate.

90% germination in 30–90 days.

Anemone (Ranunculaceae). This genus divides into two groups. The .first group are early spring bloomers with hairless seed coats, multicycle germination patterns, and intolerance of OS. The second group are taller and bloom in summer and fall, the seed is embedded in cotton in a spherical cluster, and germination is largely D-70 with curious differences between DS seed and fresh seed. A. tetrasepala seed collected in the wild germ. 70(10%)-40(40%)-70(40%) and 40-70(90% in 1-3 m) indicating that a 40J0 pattern is best.

DerivedN. C. Deno, 1993

Difficulty High Rated by us, not by the source.

Start around September 17, 2027 for a May 3 last frost. Too late for spring 2027 — that needed starting on September 16, 2026.

  3. Warm moist stratification

Steps after step 2 run on after germination.

about 6 months from start to sowing. Germination time not stated; 21 days assumed.
