About
Boronia serrulata, commonly known as native rose or rose boronia, is a species of plant in the citrus family, Rutaceae, and is endemic to New South Wales, mainly in the Sydney basin. It is an erect, woody shrub with glabrous branchlets, simple, egg-shaped leaves with fine teeth on the edges, and bright pink, four-petalled flowers on the ends of the branchlets. Grow it in full sun and partial shade and loam and sand soil. In UK gardens it is half-hardy and may need winter protection in colder areas (RHS H3). It works well for city and courtyard gardens, conservatory and greenhouse and wall side borders. It tolerates acid and neutral soils, moist but well-drained conditions and south-facing and west-facing aspects. Plant in well-drained soil in sun or partial shade.
