Growth Stages

Establishment

First 6-12 months

Young transplant developing roots and establishing base structure; small, compact form

Water regularly to keep soil consistently moist; protect from harsh winds; mulch with pine needles or compost

Vegetative Growth

Spring through early summer

Plant develops dense, feathery foliage; low mounding form; foliage may show bronze or reddish tones depending on temperature

Pinch back new growth in early spring to encourage bushiness; do not overfertilize; maintain consistent moisture

Pre-flowering

Mid to late summer

Flower buds begin forming along stem tips; foliage remains vibrant

Reduce nitrogen fertilizer; maintain good drainage; ensure adequate sunlight exposure

Flowering

Late August through October

Abundant small pink or mauve flowers densely packed on upright spikes; plants are highly ornamental

Deadhead faded flowers to extend bloom; maintain adequate moisture; avoid overhead watering to prevent disease

Winter Dormancy

November through February

Growth slows; foliage may deepen in color; seed heads persist and add winter interest

Reduce watering frequency; do not prune in late fall as this damages cold hardiness; protect in harsh climates with snow cover or windbreaks

Pollinator Support

Wildlife

Late-blooming flowers provide crucial nectar and pollen for butterflies, bees, and other late-season pollinators when other food sources are scarce. [source]
