This species is popular in cultivation, although it can be a little too big for most backyards. The attractive red bark on the young trees eventually ages to a striking red/black which constrasts well with the blue-grey foliage. The flowers attract nectar feeding birds and even when not in flower, the bark and leaves will provide year round interest.
Genus: From Greek, eu, well; and calyptos, covered; referring to the cap which covers the developing flowers.
Species: From Greek, sideros, iron; and xylon, wood; referring to having very hard wood.
