Establishment (Year 1)
3-6 months after plantingYoung plant focuses on root development and basal branching. New foliage emerges fine-textured and light green.
Keep soil consistently moist but not soggy. Avoid fertilizing. Apply 1-2 inches of mulch (pine bark or peat) around base, keeping it away from the stem. Pinch back tips lightly to encourage bushiness.
Vegetative Growth (Year 1-2)
6-18 monthsPlant develops dense, mounding form with fine needle-like foliage. Leafy branches elongate and branch further.
Water regularly during dry periods. Minimal feeding needed; if desired, use dilute ericaceous (acid) fertilizer in spring. Light pruning after flowering encourages compact shape.
Flowering (Late Summer to Fall)
8-12 weeksTerminal spikes produce distinctive double flowers in rose-pink to mauve, densely packed along erect panicles. Foliage remains evergreen.
Do not deadhead if you wish to keep winter interest; flowers fade to copper tones. Maintain steady moisture; heavy rain or drought stresses blooms. Avoid heavy fertilizing which reduces flowering.
Post-Flowering & Winter (Fall-Spring)
5-6 monthsFlower spikes dry and persist, turning bronze or copper. Foliage may deepen in color. Plant enters dormancy in cold climates but remains evergreen.
Light pruning of spent flower spikes (no more than 1/3 of current growth) in early spring improves appearance and promotes next season's blooms. Protect from heavy snow in harsh climates. Reduce watering in winter but do not allow soil to dry completely.
