Chelone glabra
flowerChelone, commonly known as turtlehead, is a native North American perennial wildflower named for its distinctive snapdragon-like flowers that resemble a turtle's head.

Seed Germination
10-14 days to germination; 4-6 weeks to grow true leavesSeeds are tiny and light-dependent. Small seedlings emerge with oval cotyledons and develop true leaves over 3-4 weeks.
Do not cover seeds; press gently into moist soil. Keep soil consistently moist. Germination occurs at 65-70°F. Provide bottom heat (70°F) for better results.
Seedling to Young Plant
Weeks 5-16 (first growing season)Plant develops a rosette of oblong, lance-shaped leaves. Growth is slow in the first year with root development prioritized.
Maintain moist soil and partial shade. Thin or transplant seedlings to proper spacing. Fertilize monthly with dilute liquid fertilizer. Protect from harsh direct sun.
Vegetative Growth
Spring and early summer (Year 1-2)Established plant develops sturdy, upright stems 2-3 feet tall with lanceolate green leaves arranged oppositely. No flowers appear.
Keep soil consistently moist. Ensure adequate shade, especially in warmer zones. Mulch to maintain soil temperature and moisture. Divide mature clumps in spring or fall.
Flowering
8-12 weeks (late August through October)Dense terminal racemes of tubular, two-lipped flowers resembling snapdragons bloom at stem tips. Colors range from pink to rose to white, rarely purple.
Deadhead spent flowers to encourage extended blooming. Continue consistent watering. Avoid fertilizing with high-nitrogen (reduces blooms). Stake tall varieties if needed in windy sites.
Seed Set & Dormancy
October through MarchFlowers fade and develop seed capsules. Foliage turns golden or reddish in fall. Plant dies back to ground in winter, disappearing completely.
Leave seed heads standing for wildlife and winter interest (or allow self-seeding). Cut back stems in late fall or early spring. Protect crowns with mulch in zone 3-4.

Harvest Tips
Chelone is grown for ornamental flowers, not harvested for food or medicine. Enjoy flowers on the plant or cut for fresh arrangements in late summer/fall. Cut stems when lowest flowers on spike are fully open. Deadhead regularly to extend blooming season. Allow some flowers to remain for seed production and wildlife food.
