Macrocarpa is a very distinctive species of eucalyptus having what Australians usually refer to as a “mallee” type habit of growth. A species that has amazing characteristics including interesting foliage, beautiful flowers, and fascinating bark. Because of the dryness of the habitats in which it evolved, this eucalyptus tends to be extremely drought tolerant, with evergreen, often wax-covered leaves, which appear in different shapes as the plant matures. Macrocarpa’s large, bluish gray leaves are very interesting and look spectacular in arrangements. Macrocarpa flowers from early spring to mid-summer producing blooms larger than a silver dollar, with brilliantly colored stamens in vibrant vivid pinks and stunning reds. The gum nuts which follow the flowers are also an interesting feature of the tree… they’re very large and have a wonderful powdery grey covering.

During a recent field trip, clusters of long pink flower spikes caught our eye. These giant Emu Trees, also known as Hakea francisiana can grow stems up to 8 feet tall. The vibrant flowers bloom within the blue-green foliage and the long sweeping style of the branches ensures that they are predominately displayed, never failing to attract attention. They take their name, francisiana, from George William Francis a Victorian botanist who established a herbarium and was the first director of the Adelaide Botanical Gardens in Australia. This hakea has been in cultivation for years but is mainly suited to Mediterranean-like climates and it flowers best in an open, very well drained areas. Francisianna is tolerant of moderate frosts and its blooms are very attractive to pollinators. Use it as a feature shrub in the garden or as an accent flower in arrangements.
