Acacia leiocalyx – Early Black Wattle

Family: Fabaceae
Packet Size: 30 seeds

Description

Acacia leiocalyx, known as Early Black Wattle or Lamb’s Tail Wattle, is a native shrub or small tree occurring from Queensland into New South Wales. It is valued in suitable native plantings for its quick seasonal colour and upright growth.

Long, narrow-to-elliptic green leaves are accompanied by slender, pale-yellow to yellow flower spikes, often flowering from winter into spring. The flowers are quite different in shape from the rounded heads of many other wattles.

Key Features

• Flowers: Elongated pale-yellow flower spikes, commonly appearing during winter and spring.
• Foliage: Long green leaves with several visible lengthwise veins.
• Plant habit: Shrub to small tree, often reaching around 6 m or more in favourable conditions.
• Garden uses: Naturalistic native gardens and suitable small-tree or revegetation plantings.

Growing Conditions

• Position: Choose a sunny, open location.
• Soil: Use a well-drained garden bed or native planting site.
• Watering: Water regularly during seedling establishment; avoid prolonged waterlogging.
• Climate: Naturally occurs across warmer parts of eastern Australia.
• Maintenance: Allow sufficient space for the developing shrub or small tree.

Seed Propagation

• Prepare: For the hard seed coat, gently rub a small area with fine sandpaper or carefully nick the coat without damaging the seed inside. Soak in room-temperature water for approximately 12–24 hours before sowing.
• Sow: Plant approximately 5 mm deep in a clean, freely draining seed-raising mix and firm gently.
• Position: Place in a warm, bright, sheltered spot out of harsh midday sun while seedlings are small.
• Moisture: Keep the mix evenly moist but not saturated.
• Germination: Timing varies with seed age, nicking or scratching the seed coat and temperature. Continue to monitor the tray if emergence is uneven.
• Transplant: Move seedlings to individual pots once they have established their first true leaves and can be handled safely.

Growing Note: Acacia leiocalyx is closely related to Acacia concurrens; the two have similar foliage and spike-shaped flowers.
