Datura metel ‘Double Purple’ (Devil’s Trumpet) [15 Seeds]


Germination Information: Some people say daturas are easy to grow from seed, but I have to be honest: I find they require a lot of patience, with germination being slow and erratic. I usually sow indoors in early to mid-spring, just pressing the seeds into the surface, and set the pot on a heat mat. It can take several weeks–even a month or more–for the first seedlings to appear, with other popping up over the following weeks.

In the hope of getting better results, I have done some poking around this winter and found other advice. I recently read, for example, that soaking the seeds for about 24 hours before sowing can help to encourage germination. I sometimes find self-sown seedlings by midsummer, so it might be worth winter-sowing a few of the seeds; some people do report good results with that. And though some sources swear by surface sowing, there are also those who say the seeds need to be in darkness to sprout. If you really want to delve into sowing options, you may find this article of great interest: Simple Method of Improved Seed Germination in Datura metel L. It does seem to indicate that a cold-water soak or a chilling period could enhance germination rates. I’m definitely going to experiment with the seeds myself this year! (I’m very glad that the article’s authors found that a cow-urine soak was not helpful in encouraging germination. I don’t think I would have been willing to go that far.)

‘Double Purple’ devil’s trumpet (Datura metel ‘Double Purple’ or D. metel var. fastuosa) produces upright, branching plants typically 3 to 4 feet tall, with broad, deep green leaves. They usually start flowering in midsummer (from an early to mid-spring, indoor sowing), with large, ruffled, upward-facing blooms that are purplish on the outside and creamy white on the inside. Some people love the fragrance, but others dislike it, so you may want to treat this as an experiment and grow just one or two the first year so see what you think.

The petals eventually drop off, and the rounded, somewhat prickly seed pods are green with deep purple mottling. When they split (if they have time to ripen before frost), you can collect the brown seeds for future sowing. Note that all parts of this plant are toxic if ingested. Full sun. Annual (or tender perennial in very mild climates).

Collected in October 2020. At least 15 seeds.
