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 them quirky. Sometimes 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. Be aware that it can take several weeks—even a month or more—for the first seedlings to appear, with others popping up over the following weeks.

If you really want to delve into sowing options, you may find this article of interest: Simple Method of Improved Seed Germination in Datura metel L. Since it indicated that a cold-water soak or a chilling period could enhance germination rates, I tried an overnight soak in cold water with a few ice cubes in 2022 and had very good results. I sowed the soaked seeds on March 6 indoors under lights and the first one germinated on March 17, with more seedlings appearing from March 22 to April 10. (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.) Interestingly, when I did my 2023 sowing, the cold-soaked seeds took two days longer to first appear than seeds that had no pre-treatment. Go figure! With treatment or without, it’s normal for germination to be slow and erratic, so please be patient with them.

‘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 starting in late August 2022. At least 15 seeds. Shipping to US addresses only.
