The Story
Plant Bio
Tetratheca ciliata is an upright or spreading Australian subshrub reaching up to thirty-nine inches in height, featuring slender stems clothed in small, whorled leaves. The downward-facing, bell-shaped flowers display deep lilac-pink petals with strongly reflexed sepals, opening from late winter through late spring.
This species is distinguished by its glandular-hairy flower stems and highly sensitive root system that demands exceptional drainage. The foliage remains deep green year-round, providing a fine-textured backdrop for the nodding blooms.

Planting
How to Grow
- Select a planting site with acidic to neutral, sandy or gravelly soil that drains rapidly.
- Position the plant in partial shade or filtered morning sun, ensuring protection from intense afternoon heat.
- Water regularly during the first growing season to establish the root system, keeping the soil moist but never waterlogged.
- Apply only low-phosphorus, native-formulated slow-release fertilizers, as standard garden fertilizers cause fatal toxicity.
Pro Tip
Never prune back into bare, leafless wood, as this species lacks epicormic buds on old stems and will fail to regenerate.
