Isotoma axillaris

Isotoma axillaris, commonly known as the Rock Isotome, Showy Isotome, or Laurentia, is a hardy Australian native perennial herb famous for its prolific, star-shaped flowers that range from bright blue and mauve to pink or white. It is a versatile choice for cottage gardens, rockeries, and containers due to its mounding habit and long flowering season from September to May

Key Features

• Appearance: Forms a dense, upright mound about 30–50 cm tall with fine, deeply-toothed green foliage.

• Flowers: Scented, 5-petaled star flowers (approx. 3.5 cm wide) that attract native blue-banded bees and butterflies.

• Hardiness: Drought tolerant once established and handles light frost, though it may die back in winter and regrow in spring.

Growing Tips

• Position: Best in full sun to part shade for maximum flower production.

• Soil: Prefers well-drained, moist soils but is highly adaptable to sandy or rocky gaps.

Maintenance:

• Pruning: Cut back hard after flowering (autumn) to encourage fresh growth and prevent the plant from becoming woody.

• Watering: While drought-tolerant, it flowers best with regular moisture during hot months.

NOTE:

The milky sap is a severe irritant. It can cause skin irritation and temporary blindness if it comes into contact with your eyes.

• Always wear gloves when pruning or handling cuttings.

• Keep away from pets and livestock as it is toxic to stock
