The Story
Plant Bio
Alpinia purpurata, the red ginger, is a clump-forming, upright tropical perennial with erect leafy pseudostems formed by overlapping leaf sheaths. The glossy green, lanceolate leaves feature parallel veins and emerge from tightly rolled sheaths that unfold vertically.
The terminal inflorescences consist of dense spikes of waxy, vibrant red bracts that enclose small, fleeting white flowers. These colorful, cone-like structures persist for weeks and are highly valued for tropical floral arrangements.

Planting
How to Grow
- Select a planting site with rich, organic, well-draining soil in partial shade to full sun.
- Amend the soil with compost to improve moisture retention while ensuring excellent drainage.
- Plant rhizomes shallowly, keeping the growing tips just below the soil surface.
- Water thoroughly and maintain consistent moisture, never allowing the soil to dry out completely.
Pro Tip
Never prune living, green, unflowered pseudostems, as they supply energy to the rhizome and are required for future flower production. Cut spent flowering stems completely to the ground annually to stimulate fresh, vigorous growth.
Keep It Thriving
Care Guide
Do
- Keep the soil consistently moist to support lush foliage and continuous blooming.
- Apply a balanced, slow-release fertilizer every six to eight weeks during the active growing season.
- Mulch heavily around the base to retain soil moisture and protect rhizomes from occasional light frosts.
Don't
- Do not plant in heavy, poorly drained clay soils that hold standing water.
- Avoid trimming green, unflowered pseudostems, which prevents future flower development.
- Do not let the plant suffer from dry soil or low-humidity conditions.
