Care Guide

Light
Full sun to partial shade; prefers at least 6 hours of direct sunlight for best flowering and structure.

Water
Moderate water during growth; establish deeper less-frequent watering. Drought-tolerant once mature. Overwatering, especially in winter, risks rot.
compost
Soil
Well-draining soil is critical; thrives in sandy, gravelly, or loamy soils. Poor soil tolerance is high; avoid clay and waterlogged sites.

Fertiliser
Minimal fertilizer required; a light application of balanced feed in spring suffices. Excess fertility promotes weak, floppy growth.
