Planting Moonflower (Datura) Seeds: Timing, Stratification, and Care

Growing Datura (Moonflower, Jimsonweed, Angel's Trumpet) from Seed

Datura seeds are easy to germinate if treated like their tomato relatives. Here’s a reliable method for gardeners in the North Carolina foothills (Zone 7a).

Sowing Schedule

• Start seeds indoors 8–10 weeks before the last frost (mid-February to early March in Zone 7).
• Lightly cover seeds with ¼ inch of soil; they need darkness to germinate.
• Keep at 70–75°F (21–24°C); germination in 10–20 days.

Seedling Care

1. Grow under fluorescent lights (40-watt shop lights) until 2 inches tall.
2. Transplant to individual cells or pots.
3. After last frost (when nights are consistently above 50°F / 10°C), harden off in shade for 10 days.
4. Plant in full sun, well-drained soil.

Cautions

All parts of Datura are highly toxic. Plant away from children and pets. In some areas it is considered invasive—check local regulations.

With proper timing, Datura rewards you with large, fragrant, trumpet-shaped blooms all summer.
