About Your New Eucalyptus macrandra Long-flowered Marlock

Eucalyptus macrandra, the Long-flowered Marlock, is a charming Western Australian native grown for its striking long, pendulous clusters of golden-yellow flowers and its compact, manageable size compared with most eucalypts.

Long-flowered Marlock grows to 6-10 metres tall and 4-6 metres wide with a spreading, sometimes weeping habit. The blue-green lance-shaped leaves complement the vivid blooms, and the smaller scale makes it a graceful choice for medium gardens, screening rows, and windbreaks where larger gums would overwhelm.

Long-flowered Marlock is hardy and adaptable, thriving in poor and saline soils with minimal maintenance. It is drought tolerant once established and also tolerates periodic wet conditions, performing well across WA, SA, VIC, NSW and southern QLD in full sun. The summer and autumn flowers attract native birds, bees, and pollinators.
