Establishment
First 6-12 monthsYoung plant with compact, bushy growth habit; variegated foliage is developing its full pattern
Water regularly to establish deep roots. Stake if necessary. Apply mulch around base, keeping away from stem. Monitor for transplant stress.
Vegetative Growth
Year 1-3Plant develops dense foliage with increasingly prominent cream and green marbling; leaves are glossy and compact
Prune lightly to encourage bushiness and maintain shape. Remove any all-green reversions to preserve variegation. Apply balanced fertilizer in spring.
Flowering
Spring to early summerProduces small, inconspicuous greenish flowers in leaf axils; flowers are dioecious (separate male and female plants)
No special care needed. Female plants will produce berries if a male pollinator is nearby. Flowers are not showy.
Fruiting
Summer through winterFemale plants develop small, bright orange-red berries (about 5mm) that mature and persist on branches
Keep well-watered during fruit development. Berries add ornamental interest but are toxic if ingested. Keep away from pets and children if concerned.
Mature
Year 3+ onwardFully established shrub reaching 3-6 feet tall and wide with dense, variegated foliage and regular flowering/fruiting cycles
Prune as needed for shape and size control. Fertilize annually in spring. Increase irrigation during extended dry periods. Remove any diseased or damaged branches.

Fun Facts
- 🌱 Coprosma is a genus of about 15 species native to New Zealand, with 'Marble Queen' being one of the most prized variegated cultivars for its distinctive cream and green mottled pattern.
- 🌱 The name 'Coprosma' comes from Greek words meaning 'smell of dung,' referring to the unpleasant odor of crushed leaves—a defense mechanism against herbivores.
- 🌱 Marble Queen is dioecious, meaning individual plants are either male (no berries) or female (berry-producing), so you need both sexes nearby for fruit production to occur.
