Melaleuca
Melaleuca spp.
treeMelaleuca trees are evergreen natives of Australia known for their distinctive papery, peeling bark that sheds in layers, creating striking multicolored trunks. They produce dense clusters of small, brush-like flowers in white, pink, red, or yellow, attracting pollinators and birds. These hardy, low-maintenance trees are valued for ornamental appeal, erosion control, and adaptability to challenging growing conditions.

Seedling
4-8 weeksTiny seedlings emerge with fine, needle-like cotyledons and minimal foliage. Growth is slow initially.
Keep soil lightly moist but not waterlogged. Provide bright, indirect light. Protect from strong winds.
Juvenile
1-2 yearsYoung tree develops thin, flexible stems with narrow, lance-shaped leaves. Plant grows slowly and steadily.
Maintain moderate watering. Support with staking if needed in windy locations. Begin light pruning to shape.
Vegetative Growth
1-2 yearsTree develops stronger branching structure and fuller canopy. Bark begins to develop characteristic peeling texture.
Reduce watering frequency as root system deepens. Prune to remove crossing branches and shape form. Fertilize sparingly.
Flowering
4-6 weeks per bloom cycle; varies by species and climateDense, brush-like flower clusters appear at branch tips in white, pink, red, or yellow. Blooms attract bees and birds.
Provide full sun for maximum blooms. Avoid over-fertilizing, which reduces flowering. Deadhead spent flowers if desired.
Mature
Ongoing for decades; trees live 50+ yearsEstablished tree with full canopy, distinctive peeling bark in multiple colors, and regular flowering. Growth slows significantly.
Water only during drought periods. Minimal fertilizer needed. Prune only for shape and removal of dead wood. Little maintenance required.

Fun Facts
- 🌱 Melaleuca trees are famous for their 'paperbark,' which naturally sheds in thin, papery layers to reveal bright colors underneath—white, cream, green, red, or orange—making the trunk a living rainbow.
- 🌱 Tea tree oil, derived from Melaleuca alternifolia, has been used by Australian Aboriginal peoples for thousands of years as a traditional medicine before becoming popular in modern wellness and cleaning products worldwide.
- 🌱 Some Melaleuca species are highly invasive outside their native Australia, particularly in Florida and other subtropical regions, creating ecological challenges despite their ornamental appeal.
