Establishment
First yearYoung plants develop compact root systems and establish evergreen foliage. Stems are thin and flexible.
Keep soil consistently moist but not waterlogged. Protect from harsh winter winds. Mulch with grit or bark to maintain cool root conditions.
Vegetative Growth
Year 2-3Plant grows slowly, forming dense, mounded foliage with needle-like or lance-shaped leaves. No flowers yet.
Maintain steady moisture. Provide dappled shade in warm climates. Minimal fertilizer needed; avoid nitrogen-rich feeds. Trim lightly to maintain shape.
Flowering
4-8 weeks (May-June in most zones)Terminal clusters of delicate, tubular to bell-shaped flowers appear at branch tips in spring to early summer. Colors include pink, red, yellow, or white depending on species.
Maintain consistent moisture. Deadhead spent flowers to encourage extended blooming. Avoid heavy pruning during flowering.
Post-Flowering & Maturity
Summer through fallFlowers fade; plant continues steady growth. Foliage remains ornamental year-round as an evergreen shrub.
Light deadheading of flower clusters. Reduce watering gradually as temperatures cool. Apply winter mulch in exposed sites in zone 2-3.
Dormancy
November-March (varies by zone)Plant enters semi-dormant state in winter. Foliage persists but growth slows dramatically. Flowers are initiated for next season.
Reduce watering significantly; allow soil to dry slightly. Protect from wind and heavy snow with a light mulch layer. Avoid fertilizer.
