Backhousia citriodora, commonly known as Lemon Myrtle, is a fragrant Australian native and one of our top recommendations for an evergreen feature tree. It produces fluffy white to creamy yellow flowers and has a strong, fresh lemon scent, commonly used in candles.
Lemon Myrtle forms a dense, upright habit ideal for use as a feature tree, screen, or informal hedge. Suited to full sun or part shade, it performs well with regular watering and responds to pruning, whether shaped into a small tree or kept compact in a pot. It is low maintenance, pest resistant, and attracts birds and bees, making it suitable for both urban gardens and larger landscapes.
This versatile tree also has culinary value, with leaves that can flavour teas, desserts, and savoury dishes. Once established, it is tolerant of mild frost and moderate drought. With evergreen foliage, seasonal flowers, and a standout fragrance, Lemon Myrtle combines beauty, resilience, and function in any garden setting.
