Establishment
6-12 monthsYoung plant (6-12 months after planting) with limited growth as root system develops.
Water regularly to keep soil moist. Mulch around base. Avoid heavy pruning. Provide afternoon shade in warmer zones.
Vegetative Growth
1-2 yearsPlant develops dense foliage and lateral branching (year 2-3). Glossy leaves emerge and variegation becomes more pronounced.
Water weekly during growth season. Apply balanced slow-release fertilizer in spring. Prune lightly to shape if desired. Remove any dead wood.
Flowering
2-4 weeksSmall, inconspicuous dark purple flowers appear in spring (March-April in most regions), primarily on stems. Female plants show more prominent flowering.
No special care needed. Flowers are self-fertile but cross-pollination improves berry set. Ensure female plants are present for berries.
Fruiting
Summer through winter (6+ months)Bright red berries develop on female plants after pollination (summer through winter). Berries persist on plant and provide winter color.
Maintain consistent watering during fruiting. Do not prune heavily during this period. Berries can cause mild stomach upset if ingested; warn children and pets.
Mature
Ongoing; plant can live 20+ yearsEstablished shrub (3+ years) forms dense, attractive structure. Foliage is thick and colorful; regular berries appear if female plant.
Water during dry spells. Prune after flowering to maintain shape and remove dead wood. Fertilize lightly in spring. Tolerates neglect once established.
