Germination guide
Datura wrightii seeds will usually germinate in 7 to 45 days, even under good conditions germination may be erratic. Sow seeds about 3mm deep in a rich and sandy seed sowing mix at about 25°C.

Soak in warm water for a day and a night, sow just below the surface of a sandy - peaty mix, keep at about 25°C, dark and moist (not damp)

Gibberellic acid (GA 3) is often recommended. Vernalized seeds will germinate better if surface sown (ie with sunlight).
