Botanical Name: Crowea exalata ‘Stellarose’
Family: Rutaceae
Origin: Australia (cultivar selection of an eastern Australian native)

Overview

Perfectly suited to Adelaide’s temperate and Mediterranean conditions, Crowea exalata ‘Stellarose’ is a compact, refined Australian native shrub prized for its masses of star-shaped, soft rose-pink flowers. Flowering occurs mainly from late autumn through spring, often peaking in winter when colour is most welcome in the garden. The neat, rounded habit and fine, deep-green foliage give year-round structure, while the flowers release a gentle citrus fragrance, especially in mild weather. Best grown in sheltered positions with good drainage, ‘Stellarose’ is ideal for courtyards, alfresco areas, pots and low native borders where subtle elegance and fragrance are desired.
