Description
Eucalyptus erythrocorys, commonly known as Illyarrie or Red-Capped Gum, is a striking native tree from Western Australia. Renowned for its vivid red bud caps that open to reveal brilliant yellow flowers, this tree creates a showy display during Djilba to Kambarang (late winter to late spring). Its smooth, pale grey bark, which sheds in ribbons, adds to its ornamental appeal, making it an eye-catching feature in any landscape.
Ideal for full sun positions, Illyarrie thrives in well-drained sandy or loamy soils and tolerates drought conditions once established. It is perfect for larger gardens, open spaces, or as a windbreak tree. Minimal maintenance is required beyond occasional pruning to shape and remove deadwood. This resilient and adaptable tree is a fantastic addition to Perth gardens, providing colour and habitat for birds and insects.
