Establishment
3-4 weeksYoung transplants develop root systems and initial compact growth with small linear leaves
Water consistently but avoid waterlogging. Protect from heavy rain and excess moisture. Ensure well-draining soil is in place before planting.
Vegetative Growth
6-8 weeks (winter dormancy in cold zones)Plant fills out with dense, fine-textured evergreen foliage, forming a tight mound 6-12 inches tall
Minimal fertilizer needed; over-fertilizing causes weak, leggy growth. Allow soil to dry between waterings. Deadhead spent flowers if desired to maintain tidiness.
Flowering
6-8 weeks (spring through early summer, typically April-June in most zones)Tiny four-petaled white flowers appear in dense, flat-topped clusters (corymbs) covering most of the foliage
Deadheading extends bloom time but is optional. Flowers are excellent for pollinators; leave some spent blooms for seeds if desired. Light shearing after bloom encourages bushier growth.
Post-Bloom & Dormancy
Late summer through early spring (varies by region)Plant retains evergreen foliage year-round; may take on bronze or purple tinges in cold weather
In cold climates, protect with light mulch to prevent frost heaving. Reduce watering in fall and winter. Do not cut back aggressively; this plant maintains its shape naturally.

Harvest Tips
