Establishment (First Year)
3-4 monthsYoung plant developing root system; slow growth; foliage appears dense and compact with small linear leaves
Water regularly but allow drying between waterings; shelter from strong winds; avoid fertilizer excess; mulch lightly around base
Vegetative Growth (Year 1-2)
6-12 monthsBush fills out with aromatic, needle-like foliage; plant reaches 1-2 feet tall; no flowers yet
Prune lightly to encourage bushiness; maintain consistent moisture without waterlogging; minimal fertilizer needed
Flowering
3-4 months (spring-summer)Delicate white or pale pink flowers appear in leaf axils and branch tips, typically in late spring through summer; very fragrant
Do not prune heavily during flowering; ensure full sun for prolific blooms; maintain moderate water; flowers attract pollinators
Fruiting & Berry Development
2-3 months (late summer-fall)Small blue-black berries develop after flowers fade; berries mature over several weeks and persist on plant through fall/winter
Reduce nitrogen fertilizer to encourage fruiting rather than excess foliage; allow berries to remain for ornamental effect or wildlife food
Dormancy/Winter
4-5 months (fall-spring)Growth slows significantly; foliage remains evergreen; berries persist and darken; plant appears dense and compact
Minimal watering; no fertilizer; protect from frost in zone 8b; prune back any winter damage in early spring

Harvest Tips
Berries can be hand-picked when fully dark blue-black (late summer-fall) for use in culinary applications or left on plant for ornamental effect. Leaves can be harvested year-round by pinching or cutting; most flavorful in spring. Cut sprigs for arrangements at any time; plants tolerate regular harvesting once established.
