Growth Stages

Establishment

6-12 months

Young plant with delicate needle-like foliage establishing root system

Water regularly (weekly) to establish deep roots; protect from strong winds; stake if necessary; avoid transplanting once established

Vegetative Growth

Year 1-2

Plant develops bushy form with fine, feathery grey-green foliage; minimal flowering

Light pruning to shape form; reduce watering frequency; apply light fertilizer (low-phosphorus); monitor for pests

Pre-flowering

Year 2-3

Foliage becomes denser; plant reaches near-mature size; flower buds begin forming

Minimal pruning to maintain shape; drought conditions may promote flowering; discontinue heavy fertilizing

Flowering

6-8 weeks, typically winter-spring

Spidery, nectar-rich flower clusters appear in red, orange, yellow, or pink depending on variety

Light watering during blooms; deadheading not essential but can encourage more flowers; attract birds and pollinators

Mature

Year 4+ indefinitely

Fully established shrub with consistent flowering cycles and minimal maintenance needs

Water only during extended drought; prune only to remove dead wood or improve shape; very pest-resistant once mature
