Plant Species of the genus Boronia
Information about this genus
Name: Boronia
Cultivation: CULTIVATION: Locate boronias in sheltered positions with the protection of other plants in sun or part-shade. The soil should be well drained with a fairly high organic content so that it does not dry out readily during hot or windy weather. If growing in pots ensure that the potting mix does not contain added fertilizers with high phosphorus levels. The flowers generally last well when picked and the plants benefit from the trimming. After flowering, up to one half of the plant can be removed to prolong life and improve bushiness. Propagation is from half-hardened tip cuttings.
Description: Noted for sweet fragrance, early spring blooms and aromatic foliage, this genus belongs to the citrus family, Rutaceae, and consists of around 100 species, the majority occurring in Australia. Ranging in size from small to medium-sized, compact, evergreen shrubs, they have simple or pinnate leaves, and the small 4-petalled flowers may be open and star-shaped or bell-like with overlapping petals. Flower colors range from white, pink, bluish mauve, red, yellow, yellow-green and brown. Some species are short lived and success is often achieved when grown in containers that can be easily moved to protected or shady positions in hot or windy weather.
