Backhousia citriodora

Australia’s fragrant gift to the garden — crush a leaf and release an intense burst of pure lemon. An evergreen native small tree producing clusters of fluffy creamy-white flowers in summer that attract bees, butterflies, and birds. Grows 3–8m tall x 2–4m wide (smaller in cooler climates).
Best in full sun in well-drained soil with a sheltered position. Suits native gardens, feature planting, screening, and even large pots.
