Establishment
First 1-2 yearsYoung plant focuses on root development with slow above-ground growth. Foliage is small, tender, and bright green.
Keep soil consistently moist but not soggy. Protect from direct sun and wind. Mulch with 2-3 inches of pine bark or leaf litter.
Vegetative Growth
Years 2-4Plant develops bushy, spreading habit with dark green evergreen foliage. Shoots remain low, typically 6-12 inches tall initially.
Maintain moisture consistency. Light feeding with acid-forming fertilizer in spring. Minimal pruning needed; let it spread naturally.
Flowering
4-6 weeks, typically May-JuneDelicate white to pale pink bell-shaped flowers appear in clusters along stems in late spring to early summer. Flowers are small but ornamental.
Ensure adequate moisture during flowering. Do not fertilize heavily as this reduces bloom. Flowers attract pollinators.
Fruiting
8-10 weeks, July-SeptemberSmall berries develop from spent flowers, transitioning from red to dark blue-black by late summer. Berries are about 1/4 inch diameter.
Continue consistent moisture. Support cross-pollination by planting multiple plants if berry production is desired. Berries persist into fall.
Dormancy/Winter
October-MarchIn cold climates, plant goes semi-dormant. Evergreen foliage persists but growth slows. In milder zones, growth continues slowly.
Mulch well in cold climates. No supplemental water needed. No pruning required. Very cold hardy once established.
