Saving and Growing Moonflower (Datura) Seeds

Moonflower (Datura) produces distinctive thorny seed pods that yield abundant seeds for saving. Proper handling ensures viability and safety.

Seed Harvesting

Wait for pods to turn brown and dry on plant. Wear gloves—pods are spiny and plant parts are toxic. Split pods over a white plate to collect seeds. Discard pod debris. Seeds resemble large, flattened tomato seeds.

Storage and Spring Starting

Store in airtight glass jars in cool, dark, dry location. Start indoors 6-8 weeks before last frost: sow ½ inch deep in warm (75-80°F), moist mix. Germination in 2 weeks. Provide 12-14 hours fluorescent light daily. Harden off after frost: 10 days in protected shade before full sun planting.

Important Safety Notes

All Datura parts contain toxic alkaloids. Keep away from children and pets. Plants readily self-sow in favorable climates but controlled propagation ensures desired placement and quantity.
