Propagation
Sow fresh seeds during spring and maintain a temperature of 16º to 24ºC.

Take soft tip or semi-hardwood cuttings during late summer to early winter and apply bottom heat.

Note:
Care should be taken when selecting a sight as the tree has vigorous roots that can lift concrete and block drains.

The Giant Water Gums habit varies from a broad dome to forest form in dense vegetation. The common name of Giant Water Gum is derived from the fact that when the tree is cut down the central core is full of water which spills out. 

Botanic information
Leaf: The leaf shape varies from elliptical to broad lanceolate with an acuminate apex. It is glossy green above and pail green on the undersides. The leaves have very small obscure oil glands and the mid rib is prominent on both sides.

Flower: The tiny pedunculate flowers appear in an axillary panicle of 4-angled branches in a cluster of 3 to 6. The calyx is campanulate and has 4-short teeth and within these teeth the petals form a cup-shape enclosing a few fine stamens. The flowers appear from late spring to early summer.

Fruit: The bluish-purple berry is rounded or slightly flattened and has a fleshy mesocarp with a large seed. The seeds are viable but the plant may be reproduced vegetatively.
