What is boronia?

In the Western part of far-away Australia grows a rare shrub belonging to the rue family (all citrus trees belong to this family as well). This evergreen shrub (up to 2 m/21 feet) has small leaves and unusually fragrant bell-shaped flowers in red, white, and pink. Boronia is an extremely decorative plant capable of decorating not only the garden landscape but also the home interior. After flowering, the petals close, and the flowers, like bright miniature lanterns, flare up on the branches for a while longer.

This beautiful shrub has been cultivated since Queen Victoria’s time. There are shrubs with flowers of unusual color: on the outside the petals are colored dark brown and on the inside yellow. Because of the dark color of the flowers and leaves in those days, boronia was often planted near the tombs. In Victorian England, for example, boronia was often planted in cemeteries because of the somewhat gloomy coloring of the upper part of the flower.

Presently there are about 15 species of this shrub in Australia differing mainly in the color of flowers. in Europe, this plant is seldomly cultivated because of its high sensitivity to variations of humidity or temperatures.

Its flowers are wonderfully fragrant, almost magical, and its essential oil is highly valued in perfumery, as it seems to combine the aromas of the rare Farnese acacia, violets, and fruits: peach, raspberry, and apricot. Many notice hints of spices in its fragrance, especially anise.
