Growth Stages

1

Establishment

3-6 months

Young plant with fine, needle-like foliage establishing a deep root system; slow initial growth

Water moderately during first growing season, then gradually reduce. Protect from harsh winds. Use well-draining soil mix.

2

Vegetative Growth

6-12 months

Plant develops dense, compact foliage with slender, linear leaves; gradual height increase

Minimal watering except during drought stress. Light pruning to shape if desired. No fertilizer needed.

3

Flowering

4-8 weeks

Distinctive small clustered flowers appear in leaf axils, typically red, pink, or bi-colored; flowers attract pollinators

Avoid fertilizing during flower development. Maintain dry conditions. Light deadheading may encourage repeat flowering.

4

Seed Development

2-4 weeks

Flowers fade and small seed capsules develop; foliage remains ornamental

Allow seeds to mature on plant if self-sowing is desired. Maintain drought conditions.

5

Dormancy/Maintenance

Variable, 2-4 months in cooler regions

Plant enters a semi-dormant phase, especially in cooler seasons; minimal growth activity

Continue drought watering schedule. No pruning needed unless removing dead wood. Frost protection in border zones.
