The Story
Plant Bio
Melastoma malabathricum is an erect, multi-stemmed evergreen shrub featuring distinctive quadrangular reddish stems covered in bristly scales. The rough, opposite leaves display three to seven prominent parallel veins running from base to tip, providing a strong structural texture.
The five-petaled flowers feature highly distinct, unequal yellow stamens shaped like sickles. In tropical climates, these purple or magenta blooms appear year-round, followed by sweet, dark purple berries that stain the mouth.

Planting
How to Grow
- Select a planting site in full sun to partial shade with acidic to neutral soil.
- Ensure the soil is well-drained, though the plant tolerates moist conditions near water margins.
- Water regularly during the establishment phase to maintain consistent soil moisture.
- Apply a balanced, slow-release organic fertilizer sparingly to avoid excessive vegetative growth.
Pro Tip
Prune lightly immediately after a flowering flush to maintain a bushy form; cutting back into old, leafless wood causes severe branch dieback.

Common Questions
Malabar Melastome questions
What zones can Malabar Melastome grow in?
Malabar Melastome is hardy in USDA Zone 10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Malabar Melastome deer resistant?
Not reliably. Deer may browse Malabar Melastome, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Malabar Melastome bloom?
Malabar Melastome typically blooms in spring through summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Malabar Melastome need full sun?
Malabar Melastome does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Malabar Melastome drought tolerant?
Yes — once established (usually after the first full season), Malabar Melastome handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
