Leptospermum petersonii, famously known as the Lemon-scented Tea Tree, is one of the most beloved Australian native shrubs for home gardens. It is highly sought after for its vibrant, lime-green foliage that, when crushed or brushed against, releases a powerful and refreshing lemon fragrance. During summer, the tree is smothered in a delicate display of small, five-petalled white flowers that attract native bees and butterflies, adding life and movement to the garden.
This plant is a versatile workhorse in the Australian landscape. It features a graceful, slightly weeping habit that makes it an excellent choice for a “soft” screen or windbreak. Because of its fast growth rate, it is perfect for new gardens where a quick sense of privacy is needed. Beyond its beauty, the high essential oil content in its leaves gives it natural insect-repellent properties, making it a functional addition to any outdoor living space where you want to keep the mozzies at bay.
Care Tips
-
Position: Performs best in full sun but will tolerate light part shade. Full sun ensures the densest foliage and the best oil production in the leaves.
-
Climate: Extremely hardy in most Australian climates, from cool temperate to subtropical. It is drought-tolerant once established and can handle light frosts.
-
Soil: Highly adaptable to most soil types, including sandy or clay soils, provided there is reasonable drainage.
-
Watering: Water regularly until established. Once mature, it is quite tough, though it appreciates occasional deep watering during extended dry periods.
-
Fertilising: Use a low-phosphorus fertiliser specifically formulated for Australian natives in early spring.
-
Pruning: Responds brilliantly to pruning. It can be kept as a neat, formal hedge, or lightly trimmed to maintain its weeping shape. Regular tip pruning from a young age encourages a bushier habit.
-
Maintenance: This is a very low-maintenance species. It is generally resistant to most pests, though keep an eye out for webbing caterpillars in some regions.
