CORYMBIA calophylla

Marri is usually a large tree to 30 metres but can take mallee form on poor sites. The bark is rough brown to grey-brown, and often has exudations of reddish gum.
It bursts into an abundance of prominent cream flowers, held outside the canopy, in mid-summer. An important tree in honey production in Western Australia.

The common name "Marri" is from the Nyoongar word for blood, referring to the gum.
Marri occurs in a range of habitats including the coastal plains and both the Jarrah and Karri forests of Western Australia in a range of soils.

Prefers a light sandy well-drained soil in an open sunny position, drought and frost resistant.

Easily grown from seed.

Note: Corymbia calophylla is one of around 80 eucalypts which were transferred in 1995 from the genus Eucalyptus to the newly created genus Corymbia. The species was formerly known as Eucalyptus calophylla.

Note: The forest giants of south Western Australia are considered to include six main species.

Corymbia calophylla (Marri) formally known as Eucalyptus calophylla

Eucalyptus diversicolor (Karri)

Eucalyptus gomphocephala (Tuart)

Eucaltptus jacksonii (Red Tingle)

Eucalyptus marinata (Jarrah)

Eucalyptus patens (Yarri)

Grow notes:

Eucalypts germinate readily from seed and are generally considered to be one of the easiest natives to grow from seed.

Depending on the species Eucalyptus seed comes in various sizes from very fine to several millimetres long.
As a rule of thumb seed that is fine should be sown on the surface of a porous mix and not buried. Seeds 1 to 2 mm in diameter can be covered very lightly and seeds from 2 mm up can be sown to a depth as the seed size.

Although seed can be sown most of the year in many parts of Australia seed is generally best sown in spring or autumn in temperate climates, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C

1. Sow seed at a depth of 2-3 mm in a seed-raising mix.
2. Water with a fine mist spray to avoid disturbance of the seed.
3. Place in a warm shaded or semi-shaded position to avoid dying out.
4. Keep warm & moist, avoid drying out or waterlogging the growing mix.
5. Germination generally occurs in around 10-28 days in the right condition.

General note: Seeds of many natives are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they are discarded.
