Growth Stages

1

Establishment

3-6 months

Young transplant with developing root system and compact mound of fine, needle-like foliage

Water regularly to establish roots. Mulch lightly around base (not piled against stems) with sandy soil or grit. Protect from harsh winds in first winter.

2

Vegetative Growth

Spring to early summer

Plant develops bushy, mounded form with dense, fine-textured green foliage

Pinch back or lightly prune after flowering to maintain compact shape. Avoid heavy pruning into old wood. Feed sparingly with ericaceous fertilizer in spring if needed.

3

Flowering

July to October

Delicate white tubular flowers with conspicuous golden-yellow anthers appear densely along stems

Flowers attract pollinators. Deadhead spent blooms if desired to encourage tidiness, though not necessary. Maintain consistent moisture during flowering.

4

Dormancy

November to February

Foliage persists but growth slows; plant remains evergreen with attractive fine texture

Reduce watering in winter but do not allow soil to dry completely. Protect from harsh winds and heavy snow. In colder zones, provide wind protection or sheltering.
