Clitoria ternatea var. pleniflora, commonly known as butterfly pea or blue pea flower, is a climbing herbaceous perennial in the Fabaceae family originating from tropical Asia. The double-flowered variety produces striking, vibrant blue flowers with characteristic enlarged petals. This species requires proper seed pre-treatment to overcome its hard seed coat dormancy, making successful germination achievable with scarification and soaking.
Before sowing
Mechanical scarification followed by water soaking is essential; achieves maximum germination rates of 80-95%
Sowing
What to expect
Tips
Maintain warm substrate temperature between 24-27°C for optimal germination. Seeds with hard coats may require both mechanical scarification and soaking for best results. The radicle typically emerges within 48-72 hours, with seedlings visible within 3-6 days depending on depth. Start seeds indoors 6-8 weeks before last frost in temperate climates. Seedlings require bright, indirect light and consistent moisture; harden off gradually before transplanting outdoors after all frost danger has passed. Keep seedlings out of direct sunlight initially. Reduce watering once seedlings establish true leaves. Some sources indicate soil inoculants may improve germination success.
