Growth Stages

1

Establishment

4-6 weeks

Newly planted transplant focusing on root development with minimal top growth

Water regularly (but not excessively) for first 4-6 weeks to encourage root establishment. Avoid fertilizing; plant is naturally low-fertility adapted.

2

Vegetative Growth

Spring to early summer, 6-8 weeks

Compact bushy shrub developing multiple stems and narrow linear foliage

Light pruning in early spring to shape and encourage branching. Maintain moderate watering during active growth. No nitrogen-heavy fertilizer needed.

3

Flowering

Late spring through fall, 4-5 months

Abundant red tubular flowers (1-2 inches long) appear at branch tips; flowering intensifies with heat and drought stress

Deadhead spent flowers to encourage continuous blooming. Minimal supplemental water; allow some drought stress to trigger flowering. Do not over-fertilize.

4

Late Season/Dormancy

November through February, 3-4 months

Flowering continues but slows in fall; evergreen foliage persists; minimal growth in winter

Reduce watering significantly. Do not prune hard in late fall; light tidying only. In zone 8, provide wind protection or light mulch if hard freeze expected.
