Leptospermum erubescens, commonly known as Roadside Tea Tree or Pink Tea Tree, is a beautiful Australian native shrub known for its delicate white to pink flowers. It’s part of the Myrtaceae family, like other tea trees, and it’s often used in native gardens for its attractive foliage and flowers. Leptospermum erubescens is an attractive shrub that brings colour and structure to native landscapes. It’s low-maintenance, drought-tolerant, and provides habitat and food for pollinators. Ideal for sandy or low-fertility soils, it makes a lovely addition to gardens, particularly in coastal or dry regions.

Description

Leptospermum erubescens is a medium shrub, typically reaching heights of 1–3 metres, with an upright and bushy habit. Its leaves are small, narrow, and bright green, usually around 5–15 mm long. The leaves are aromatic when crushed, releasing a pleasant scent typical of tea tree species.

The flowers are the standout feature of this plant, blooming in abundance in late winter and spring. They are small, around 1–1.5 cm in diameter, with five petals and range in colour from white to a soft pink, sometimes with darker centres. The flowers attract bees, butterflies, and other beneficial insects, adding biodiversity to the garden.

Distribution

Leptospermum erubescens is native to Western Australia, particularly in regions with sandy soils and well-drained sites. It’s commonly found in areas with poor soils, coastal dunes, and heathland environments. Its ability to thrive in sandy, dry, and well-drained soils makes it ideal for coastal gardens and other low-fertility landscapes.

Growing Leptospermum erubescens from Seed:

Growing Leptospermum erubescens from seeds is a straightforward process, and the plant’s adaptability makes it a low-maintenance option in the garden. Here’s a step-by-step guide:

Seed Collection: Seeds are contained in small, woody capsules that mature after flowering. Once the capsules dry out, they release tiny seeds. Collect them in late summer when they are fully mature. We have done that for you!

Seed Treatment: Leptospermum erubescens seeds do not require special treatment. They can be sown directly into seed-raising mix however they may benefit from a drench in smoky water, add unpolluted wood ash to water, shake and drench seeds after planting.

Sowing: Use a well-draining seed-raising mix. Scatter the seeds thinly on top of the soil, as they are very small, and cover lightly with a thin layer of soil or vermiculite. Do not bury them deeply, as they require light to germinate.

Positioning: Place the seed tray in a warm, bright location with indirect light. Tea trees prefer full sun but will germinate best in protected conditions.

Watering: Mist the soil lightly to keep it consistently moist but not waterlogged. Over-watering can lead to fungal issues. Germination usually takes 2–4 weeks under optimal conditions.

Transplanting: When seedlings reach around 5–10 cm in height and have developed several sets of leaves, they can be carefully transplanted into individual pots. Allow them to grow and strengthen in pots until they are large enough to plant out.

Final Planting: Choose a site with full sun and well-draining soil for best results. Leptospermum erubescens tolerates poor soils, so it doesn’t require high fertility. Once transplanted, water the seedlings well to establish them, but be careful not to over-water as the plant is drought-tolerant once established.

Maintenance: Prune lightly after flowering to encourage bushiness and maintain shape. Once established, L. erubescens is hardy, drought-tolerant, and requires little attention, making it an excellent low-maintenance shrub for native gardens.
