About Boronia microphylla Sieber ex Rchb.
Boronia microphylla Sieber ex Rchb. is a shrub that reaches a height between 0.3 and 1.0 meters, or 1 and 3 feet. Its youngest branches are covered in small warty glands and scattered bristly hairs. This species has pinnate leaves with between 5 and 15 leaflets. The leaf rachis measures 3 to 16 millimeters or 0.1 to 0.6 inches long, and the petiole is 2 to 8 millimeters or 0.08 to 0.3 inches long. The leaflets are shaped like spatulas or wedges, measure 3 to 8 millimeters or 0.1 to 0.3 inches long and 1 to 4 millimeters or 0.04 to 0.2 inches wide, and are glabrous. Its flowers range in color from pink to purplish, and are mostly arranged in groups of up to five in the upper leaf axils, on a stalk that is 3 to 10 millimeters or 0.1 to 0.4 inches long. The four petals are 5 to 8 millimeters or 0.2 to 0.3 inches long and glabrous. Flowering takes place from October to February. This boronia grows in heath and forest in coastal areas, ranging from north of Moruya in New South Wales to near Stanthorpe in Queensland, and extends inland as far as the Great Dividing Range. Most boronias are not easy to grow in gardens, but this species is one of the hardiest when grown in a protected position and provided with adequate water. It propagates most easily from cuttings.
