Eucalyptus erythrocorys – Illyarrie

A small mallee gum tree growing from 4-8 metres tall, with outstanding large golden yellow flowers in late summer to early autumn. The buds are equally attractive, being bright red, and the following gum nuts are large and ornamental. It has sickle shaped leaves, and smooth creamy brown bark. This tree responds well to pruning, so can be trimmed to size and shape. It comes from the mid coast of Western Australia where it grows on limestone soils, so is at its best on alkaline soils. Highly bird attracting.

Once you have found the plant that you want, the next step is to find where to get it. Nurseries stock a good range of plants, but due to space and supplies, they may or may not have the wanted plant in stock. If they don’t, they may be able to order it in for you.  Specialist nurseries are also able to give great advice, and if they don’t have the plant you want, they can often suggest alternative plants that will be just as good for you.
