Tristaniopsis laurina 'Luscious' (Luscious Water Gum)

Tristaniopsis laurina 'Luscious', commonly known as Luscious Water Gum, is an improved Australian native evergreen tree prized for its glossy oversized foliage, vibrant copper-red new growth, attractive bark, and masses of fragrant yellow flowers. Selected from the popular Water Gum, this cultivar offers a denser growth habit and significantly larger leaves, making it a premium feature and shade tree for modern landscapes.

The rich green foliage creates a lush, tropical appearance that has made Luscious Water Gum a popular native alternative to exotic trees such as Magnolia. New growth emerges in striking copper to red tones before maturing to deep glossy green, providing year-round colour contrast and ornamental value.

During summer, clusters of fragrant yellow flowers appear throughout the canopy, attracting birds, bees, and beneficial pollinators. Mature trees also develop attractive mottled bark that peels naturally to reveal cream and cinnamon-coloured tones beneath.

Its adaptability, strong structure, and low-maintenance nature make it a popular choice for residential gardens, commercial landscapes, streetscapes, parks, and large feature plantings.
