Seed Germination
2-3 weeksTiny seedlings emerge with cotyledons; very delicate and slow-growing initially
Provide bright light, well-draining soil, minimal water. Keep soil barely moist. Seeds germinate in 2-3 weeks.
Seedling to Young Plant
2-4 monthsSmall shrub develops true leaves and deeper root system; growth remains slow the first year
Reduce watering frequency as roots establish. Provide full sun. Light compost drench acceptable but not necessary. Transplant carefully to avoid root disturbance.
Establishment
6-12 monthsShrub fills out with more foliage, reaching 2-4 feet tall and wide; root system deepens
Minimal irrigation needed during dry season once established. No fertilizer required; thrives in poor soils. Can prune lightly to shape if desired.
Flowering
4-6 months (spring-fall)Abundant white, pink, or red flower clusters appear on branch tips; flowers attract bees, butterflies, and hummingbirds
No deadheading required; let flowers dry on plant for seed production and winter interest. Flowering occurs spring through fall with peak in spring and early summer.
Seed Production & Maturity
OngoingFlowers dry and develop seeds; plant becomes woody and established; evergreen foliage persists year-round
Leave spent flowers for wildlife seed source and visual interest. Mature plants are fully drought-tolerant and fire-resistant. No maintenance required.
