Growth Stages

1

Establishment

6-12 months

Young plant focuses on root development; growth is slow to moderate with few branches

Plant in spring; water regularly but allow soil to dry between waterings; protect from strong winds; do not fertilize heavily

2

Vegetative Growth

1-2 years

Plant develops woody stems and narrow, lance-shaped grey-green leaves; canopy fills in gradually

Minimal pruning; allow natural shape to develop; maintain consistent but sparse watering; very low fertilizer needs

3

Pre-Flowering

6-12 months before first blooms

Stems thicken and plant reaches mature size; foliage becomes denser

Light pruning only if needed to shape; continue low water regimen; no heavy feeding

4

Flowering

4-8 weeks per bloom cycle; may flower multiple times yearly

Distinctive cone-shaped flower heads appear at branch tips, surrounded by colorful papery bracts; blooms typically last 4-6 weeks

Reduce watering slightly during peak bloom; flowers attract birds and insects; deadhead spent flowers to encourage more blooms

5

Mature

Indefinite; long-lived plant

Established plant 3-6 feet tall with consistent flowering; hardy and low-maintenance

Minimal watering except during drought stress; no fertilizer needed; prune lightly after flowering to maintain shape
