Why you should grow it
Brazilian Red Cloak is a statement shrub that turns heads year-round. Through the cooler months, it produces brilliant red bracts that frame delicate white flowers — the contrast is stunning. Even out of bloom, its oversized, glossy leaves bring tropical texture and richness to every corner of your garden.
How To grow and Basic Care
Megaskepasma loves warmth, humidity, and a steady supply of moisture. It flourishes in tropical to subtropical climates, and also grows well in frost-free coastal regions with some shelter.
Ideal growing conditions:
- Temperature: Between 18–30 °C; protect from frost.
- Sunlight: Full sun to part shade (avoid hot, dry winds).
- Soil: Rich, well-drained, and full of organic material.
- Water: Keep consistently moist but avoid soggy soil.
- Humidity: Prefers humid conditions — mist occasionally in dry climates.
- Mulch: Maintain a thick layer to conserve moisture and protect the roots.
Tip: The sunnier the spot (with mild afternoon shade), the heavier and more colourful the blooms.
Planting tips
- Select a warm, sheltered location with morning sun.
- Enrich the soil with compost or aged manure.
- Position the shrub so the top of the root ball sits level with the soil surface.
- Water thoroughly after planting and apply mulch to retain soil moisture.
- Maintain 1.5–2 m of spacing between plants for best airflow and growth.
Perfect as a feature shrub, hedging plant, or tropical backdrop under palms or larger trees.
Care and maintenance
While flowering Megaskepasma can deadheaded to maintain appearance and then it can be pruned to shape, usually in spring.
- Pruning: Trim after flowering to maintain shape. Harder pruning in spring encourages dense new growth.
- Deadheading: Remove old flower spikes to tidy the plant and promote fresh blooms.
- Fertilising: Apply a slow-release fertiliser in spring and late summer.
- Watering: Keep soil moist year-round, especially in hot weather.
- Mulching: Refresh annually to maintain soil health and protect roots.
Note: Not frost-hardy — in cooler climates, position near a warm wall or grow in a large pot that can be moved indoors over winter.
How to Propagate
Megaskepasma is one of the easiest shrubs to propagate:
- Take semi-hardwood cuttings about 15 cm long in late spring or early summer.
- Remove lower leaves, dip in rooting hormone, and insert into moist potting mix.
- Keep warm and humid; roots usually form within 4–6 weeks.
- Transplant new plants once well established.

We Are Asked
Is Brazilian Red Cloak suitable for pots or containers?
Yes, it grows beautifully in large pots as long as it has rich, well-drained soil and regular watering. Container growing is ideal in cooler areas because you can move the plant to a sheltered position during cold weather.
Why isn’t my Brazilian Red Cloak flowering?
Lack of sunlight is the most common reason. Ensure it receives at least 4–6 hours of sunlight per day. Over-fertilising with high-nitrogen products can also reduce flower production.
Can I grow Brazilian Red Cloak in cooler climates like Melbourne?
Yes, but with care. Grow it in a protected spot (such as a northern-facing wall) or in a large pot that can be moved indoors or under cover during frosty nights.
