Growth Stages

Establishment

2-3 months

Young plant settling in, developing root system; foliage may appear slightly stressed initially

Water regularly but allow soil to dry between waterings. Shelter from strong winds in first season. Do not fertilize heavily.

Vegetative Growth

Spring through early summer

Compact, bushy growth with dense small leaves; plant fills out its natural mounding shape

Minimal pruning needed. Light shaping after flowering promotes bushier form. Reduce watering as plant establishes.

Flowering

6-12 weeks (spring or summer depending on variety)

Delicate flower spikes emerge from leaf tips in shades of purple, pink, white, or bicolor; flowers attractive to pollinators

Allow plants to flower; deadheading not necessary but light trimming after bloom promotes tidiness. No fertilizer needed.

Dormancy/Slowdown

November-February

Growth slows in winter; foliage remains evergreen and ornamental; plant takes on darker, more compact appearance

Reduce watering significantly. Do not prune in late fall or winter. Provide frost protection in zone 8.

Maintenance

Ongoing (mature plant)

Established plant in steady growth; foliage remains dense and attractive year-round

Water only during drought. No fertilizer needed; feed lightly once yearly in spring if desired. Minimal pruning keeps shape compact.

Companion Planting

Plan your garden →

Plant with:

Lavender Santolina Cistus (rock rose) Rosemary Ornamental grasses (Festuca, Stipa) Catmint (Nepeta) Sedums and other succulents Dwarf conifers

Avoid planting near:

Moisture-loving plants (hostas, astilbe, ferns) Heavy feeders requiring rich, moist soil Plants sensitive to root competition

Common Pests

Spray with insecticidal soap or neem oil; improve air circulation; inspect regularly
Prune affected branches; spray with horticultural oil in dormant season
Spray undersides of leaves with insecticidal soap; reflective mulches deter them
Improve drainage immediately; reduce watering; may require removal if severe; use well-draining soil for future plantings
