CASUARINA glauca
Swamp Oak

Characteristics: Tree 10-15 metre spread 8-20m
Seed per packet: Approx. 200

Casuarinas are often referred to as 'native pines' due to the similarity in their foliage to pine needles. These are true flowering plants; unlike the conifers they resemble, individual plants are male or female.
Casuarina glauca can grow up to 20m high and are known for their rough bark and fine leaves. They are salt tolerant and can tolerate drought, flooding and waterlogging.
A large she-oak from NSW and Qld, they are a great option for wet or swamp-like areas. However, they tend to sucker, so it is better not to plant them near infrastructure. They are better suited to larger parks and gardens.
Their timber is excellent for crafts and as fuel.
The indigenous people have used their timber to extract resin. These trees are also an important food source for red and yellow-tailed black cockatoos.
Best sown in spring avoid the coldest and hottest months of the year. The optimum temperature for germination for this species is around 22-25°C.
Sow seed on the surface of a porous seed-raising mix.
Sprinkle a very light covering of the seed-raising mix over the seed to hold the seed in place. Do not bury the seed too deeply.
Water with a fine mist spray to avoid disturbance of the seed.
Place in a warm, shaded, or semi-shaded position to avoid dying out.
Keep warm & moist
Germination: 2-6 weeks.
Storing at 3-5°C will maintain the viability of the seed for several years.
*Please note:
- Please do not be too hasty to discard seeds that do not germinate; seeds will often lay dormant until the conditions are similar to their natural germination requirements.
- As with all seeds, they must have adequate water to keep them moist but not too wet.
- These growth notes are provided as guidance only and do not guarantee successful germination.
