Callistemon





It is possible to see Callistemon being used more frequently now in ornamental planting as local nurseries extend their ranges in plants suitable to the climate in Tunis.

"Callistemon is a genus of 34 species of shrubs in the family Myrtaceae, all of which are endemic to Australia. It is sometimes considered a synonym of Melaleuca, and four Callistemon species from New Caledonia were were moved to that genus by Lyndley Craven and John Dawson in 1998. Callistemon species are commonly referred to as bottlebrushes because of their cylindrical, brush like flowers resembling a traditional bottle brush. They are found in the more temperate regions of Australia, mostly along the east coast and south-west, and typically favour moist conditions so when planted in gardens thrive on regular watering. However, at least some of the species are drought-resistant.

Flower heads vary in colour with species; most are red, but some are yellow, green, orange or white.


They are relatively slow growing though in time the larger species can grow up to 15 m (49 ft). Some are ground-hugging, and grow to only 0.5 m (1.6 ft). The leaves are linear to lanceolate and are not shed in the winter.

 

They have been grown in Europe since a specimen of C. citrinus was introduced to Kew Gardens in London by Joseph Banks in 1789."
