Lonicera canadensis

!

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.

H

Use repeated cycles of 4°C, then 20°C for 3 months each. Germination is very prolonged.
Lonicera caprifolium

Pulpy coat inhibits germination. Remove by soaking and rinsing in clean water daily for approximately 7 days. Discard water.

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

F

Sow @ 4°C.
