A fast-growing imposing species of eucalypt with a tall straight trunk that can grow 30 to 65 m tall that sheds its bark as it matures to expose a smooth blue-grey and white bark although the rough bark usually remains at the base of the trunk.

Endemic to eastern Australia.
Grow notes:
Eucalypt's 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. Seed 1 to 2 mm in diameter can be covered very lightly and seed 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
- Sow seed on surface of a porous seed raising mix. The seed will lodge in the the pores of the mix once watered.
- Sprinkle a very light covering of the seed raising mix over the seed if required to hold the seed in place. Do not bury seed deeply.
- Water with 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, avoid drying out or waterlogging the growing mix.
- 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.
Although seeds can be sown most of the year if you avoid the coldest and hottest months, spring is generally the best time to sow.
The grow mix should be well-draining, preferably with organic compost. This will replicate the soil they require in nature.
A potting mix is not recommended.
- Sow fine seeds on the surface and cover lightly with the grow mix or vermicule. Do not bury the seed deeply.
- For larger seeds, sow to a depth of the seed size.
- Water with a fine mist spray to avoid disturbance of the seed.
Germination occurs in around 10-28 days at a soil temperature of 18-22°C
*Please note:
- Please do not be too hasty in discarding seeds that do not germinate; seeds will often lay dormant until conditions are like their natural germination requirements.
- All seeds must have adequate water to germinate; keep them moist but not too wet.
- These growth notes are provided as guidance only and do not guarantee successful germination.
- Customers should do their due diligence and ensure they are suited to their region.
