Drosera intermedia Seeds Require Cold Stratification

Drosera Intermedia

Jason harvested seed from his D. intermedia and asked if cold stratification is needed.

Yes—All North American Perennials Need It

Jeff Dallas confirmed: except for Venus flytraps, all North American perennial carnivorous plant seeds require cold stratification.

Easiest Method

Sow seeds on appropriate media (peat/sand), leave pots outdoors for winter. Protect from heavy rain to prevent washing away. Seeds experience natural cold/damp cycles and germinate in spring.

Good Growing!
