Eucalyptus marginata ssp thalassic, blue-grey leaves contrast with the green leaves of the more common Eucalyptus marginata.
Also known as Jarrah in the Aboriginal language, is in the southwest region of Western Australia.
These trees can grow up to 40 meters tall and have a trunk width of approximately 3 meters in diameter.
The leaves are typical Eucalyptus lanceolate in shape, with a lighter vein on the outer edge. The bark of the Jarrah tree sheds in fibrous strips.
The flower buds appear in clusters and bloom as creamy white flowers during Spring.
Eucalyptus marginata is known for its natural regenerative structure, which allows it to regenerate after bushfires.
It is also an important ecological tree, providing habitats for large numbers of wildlife, especially birds and bees.
The timber from Jarrah trees is highly valued and used for flooring, panelling, fencing, and outdoor furniture. Once seasoned, it becomes very hard and durable, making it ideal for outdoor structural work.
Early settlers also used Jarrah wood as railway sleepers and exported it back to the UK, where it was also used in the London Underground.
Eucalyptus marginata can live for up to 500 years.
Eucalyptus marginata subsp. thalassica is typically found in the northern Darling Range and north to New Norcia.
Although seed can be sown most of the year around if you avoid the coldest and hottest months of the year, the best time to sow is generally spring.
- The grow mix should be free draining preferably with some organic compost well mix through. This will replicate the soil they require in nature.
- Potting mix is not recommended.
- Sow fine seeds on the surface and cover lightly with the grow mix, do not bury the seed deeply.
- For larger seed sow to a depth of the seed size.
- Water with a fine mist spray to avoid disturbance of the seed.
Germination generally occurs in around 10-28 days at a soil temperature of 18-22°C
*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 germinate; keep them moist but not too wet.
- These growth notes are provided as guidance only and do not guarantee successful germination.
- The customer should do their due diligence that they are suited to their region
