Establishment
3-6 monthsYoung transplant developing root system and initial growth. Plant appears small with minimal branching.
Water regularly (weekly) during first growing season to establish deep roots. Provide afternoon shade in hottest climates. Protect from frost if in zone 8.
Vegetative Growth
6-12 monthsPlant develops branching structure and fine, feathery foliage. Gradual increase in size and fullness.
Reduce watering frequency as plant establishes. Light pruning to shape plant and encourage bushiness. Minimal fertilizer needed—too much nitrogen promotes weak growth.
Flowering
Spring through first frost (6-8 months in warm climates)Delicate purple-pink flowers appear on terminal spikes, typically spring through fall. Attractive to hummingbirds and pollinators.
Maintain dry conditions to promote flowering. Deadhead spent flowers to encourage continuous blooming if desired, though self-seeding is allowed. Avoid overhead watering to prevent fungal issues.
Dormancy & Winter
3-4 monthsPlant slows growth in cooler months. May lose some or all foliage in zone 8-9. Stems remain visible and attractive.
Cease or greatly reduce watering. Provide frost protection (mulch, shelter) in zone 8 and marginal zone 9 areas. Do not fertilize. Prune dead wood after danger of frost passes in spring.

Common Pests
-
Ensure excellent drainage; avoid overwatering. Remove affected plant material. Apply fungicide if root rot is confirmed. Consider replanting in raised bed with better drainage.
-
Spray with horticultural oil during dormancy or early growing season. Hand-remove if infestation is light. Encourage natural predators like ladybugs.
-
Strong spray of water from hose; insecticidal soap for heavy infestations. Plant attracts natural predators that usually keep populations in check.
