Meconopsis baileyi 'Alba'

!

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.

Resents transplanting.

A

Sow @ 20°C. Seed germinates within 3 months.
seedlings must be grown at less than 20° and can overwinter at -20°, prick out while small, seed is viable for at least 6m

C

Sow @ 20°C for 3 months, then place @ 4°C for 3 months.
Probably need dark to germinate. Göte Svanholm (Mid-Sweden) provides this advice: 6 month storage has no ill effect in my experience. Seedlings will survive Swedish winters with -20°C unharmed - even in pots. They will NOT survive greenhouse temperatures. Keep below 20°C at all times. Prick out in summer when big enough to handle well since they easily overcrowd in pots.
