Flowering
8-12 weeks (late spring through mid-summer)Tall flower stems (24-36 inches) emerge with pink to magenta five-petaled flowers in loose clusters (panicles)
Deadhead spent flowers to encourage continuous blooming. Stake tall varieties if needed. Water during dry periods.
Seed Development
3-4 weeksFlowers fade; seed pods (capsules) develop and ripen to brown, containing numerous small black seeds
Allow some flowers to go to seed if self-seeding is desired, or deadhead to prevent unwanted seedlings
Dormancy
4-6 months (fall through early spring)Foliage dies back after frost or late summer decline; plant enters rest period

Harvest Tips
For cut flowers, harvest in early morning when blooms are just fully open; cut stems at an angle and immediately place in water. For seed collection, allow flower heads to dry on the plant, then cut and collect seed pods when brown and papery (late summer). Store dried seed pods in cool, dry place until ready to sow.
