Passiflora sp. Passionvine Cold stratification. Still cold stratifying and will be moved soon (might take multiple cold/warm cycles) (1/24). 1
Escobaria missouriensis var. robustior Plains nipple cactus Sow under constant florescent light with high humidity until germination (1-7 weeks) Planted (~1/30). Started sprouting (2/8). 1
Zanthoxylum sp. Toothache Tree Very small seeds must be scarified, then briefly (less than 30 days) cold stratified. 1
Asclepias incarnata Swamp Milkweed Soak the seeds in hot water for 3 days. Germination will start in 3 days and lasts up till three weeks. Change the water every 12 hours with fresh hot water.

Without the hot water soaking seed is slow and needs cold treatment for best germination but the hot water speeds things up very much.
