How to germinate Lilium columbianum seeds:

Immediate hypogeal type. Cool germination (small bult first, single leaf later). Soak seed 24 hours. Mix with 3 tbsp of just moist sand/milled peat medium in resealable baggie. Give 9-11C. Higher or lower temps not ideal. Germs in 30-60 days. True leaf forms 60-90 days after Keep watch! Transplant leafed seedlings into pots to grow on. Unsprouted seed? Give 3 months 2C & repeat 9-11C cycle. Prefers full sun; very well draining acidic soil. I’ve seen these growing in very coarse soils with a thin layer of humus where the bulb is well seated in the coarse soil (mix of sand, gravel and humus). Drought tolerant. Up to 30 blooms/stem. Can flower 3  yrs after transplant.
