EUCALYPTUS diversicolor - Pure Seed 1g

Eucalyptus diversicolor is a tall forest tree. It is Western Australia's tallest tree and one of the two tallest hardwood flowering plants in the world.

Karri has smooth deciduous bark which changes colour as it ages and, as it sheds reveals multi-coloured patterns in pink through to white. Its leaves are 9-12 cm long, lance-shaped to elliptical, dark green on the upper surface and pale green below.
The flowers are creamy yellow occurring at the leaf axils in summer.

Its timber is used for structural hardwood and for the manufacture of indoor and outdoor furniture. It is also an important tree for honey production.

Native to the high rainfall areas of the south-west of Western Australia.

Prefers deep loams in a protected sunny position, drought and frost tender.
Seed in chaff

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 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 of the seed width.

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 on the surface of a porous seed-raising mix.
2. Sprinkle a light covering of the seed-raising mix over the seed. Do not bury the seed deeply.
3. Water with a fine mist spray to avoid disturbance of the seed.
4. Place in a warm shaded or semi-shaded position to avoid dying out.
5. Keep warm & moist, avoid drying out or waterlogging the growing mix.
6. 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 were discarded.
