Fun Facts
- 🌱 Pimelea ferruginea is endemic to Western Australia and is named 'rice flower' because its tiny clustered flowers resemble grains of rice.
- 🌱 The plant is exceptionally fragrant, particularly in warm weather, and its scent intensifies when flowers are brushed or touched.
- 🌱 Despite being native to Australia, this species is sensitive to root rot and requires very well-draining soil—it is one of the more challenging Australian natives to cultivate outside its native habitat.
