Establishment
6-12 monthsYoung plants developing stronger stems and deeper root systems; reaching 12-24 inches tall

Vegetative Growth
1-2 yearsPlant rapidly increasing in height and branching; developing full foliage; no flowers yet

Water consistently during flowering season. Deadhead spent flowers to encourage more blooms. Reduce nitrogen fertilizer to promote flowering over foliage.
Dormancy/Post-Bloom
3-4 months, typically winterPlant may lose leaves in cooler climates or remain semi-evergreen; minimal growth and blooming
