Casuarina torulosa is an evergreen tree that can grow up to 15.00 metres tall.
It is harvested from the wild for local use as a medicine..
Australia - New South Wales, Queensland.
Coastal eucalyptus forests and on moist fertile soils in hilly eucalyptus forests[
]. Coastal hills and ranges as understorey in open forest to tall open-forest, in a wide range of soils[
Requires a well-drained moisture-retentive soil in full sun[
]. Succeeds in most soils and aspects in Australian gardens[
Tolerates temperatures down to at least -7°c in Australian gardens[
] although this cannot be translated directly to British gardens due to our cooler summers and longer, colder and wetter winters. It experiences frost and snow in parts of its native range[
], and so some provenances should succeed outdoors at least in the mildest areas of the country[
This species has a symbiotic relationship with certain soil micro-organisms, these form nodules on the roots of the plants and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[
A dioecious species, at least one male plant is required for every 5 - 6 females in order to produce seed[
Wood - tough, durable. Used for veneer and joinery, it is also a very good fuel[
Seed - sow late winter to early summer in a greenhouse and only just cover the seed[
]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Cuttings of half-ripe wood, mid summer in a frame[
