Anemone trullifolia 'Lutea'

L

Give sown seeds several weeks @ 20°C to imbibe water (perhaps even germinate!), then expose to fluctuating outdoor winter temperatures including freezing for 3 months. Gradually increase light and temperature in spring. See https://www.youtube.com/watch?v=SO_KKbGYTEM

Anemone tschernaewii

!

Sow immediately. The viability of these seeds is short or the species propagates best with fresh seed. Stored seed might be coaxed into germination with temperature cycling and patience.

B

Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Anemone tuberosa

!

Sow immediately. The viability of these seeds is short or the species propagates best with fresh seed. Stored seed might be coaxed into germination with temperature cycling and patience.

C

Sow @ 20°C for 3 months, then place @ 4°C for 3 months.
seedlings go dormant mid summer, need little water
Anemone virginiana

!

Sow immediately. The viability of these seeds is short or the species propagates best with fresh seed. Stored seed might be coaxed into germination with temperature cycling and patience.

B

Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.

hydrophilic, sow as soon as seed is ripe; ; will not germinate if seed has dried; if stored, must be put in plastic bag with barely damp vermiculite; keep them warm during summer, coolish towards the fall and then 4⁰C at the onset of winter. Do not store them in the freezer because the formation of ice crystals will damage cell membranes
