Establishment (Young Transplant)
6-12 monthsSmall shrub with sparse fine foliage beginning to fill in; minimal flowering
Water regularly but allow soil to dry between waterings. Protect from extreme wind. Prune lightly to encourage branching. Mulch lightly around base (avoid mounding against stem).
Vegetative Growth
1-2 yearsShrub develops bushy form with increasing density of fine, feathery foliage; small linear leaves
Reduce watering as plant becomes established. Prune selectively to shape and maintain compact form. Remove any dead or weak growth. Minimal fertilizer needed.
Flowering
4-6 months (spring-fall, variable by region)Small delicate pink, purple, or lavender tubular flowers appear along branch tips; blooms densely in favorable conditions
Maintain dry conditions to encourage blooming. Avoid excessive water or nitrogen-rich fertilizers. Light deadheading improves appearance but not necessary. Peak bloom in late spring through fall.
Mature Shrub
Indefinite (long-lived perennial shrub)Full-sized plant, typically 2-4 feet tall and wide, with abundant fine foliage and regular flowering cycle
Water only during extended drought or establishment phase. Prune annually after flowering to maintain shape. No fertilizer required in native/arid soils. Extremely low maintenance.
