#FlowersOnFriday: The 'operculum' is a defining feature of the eucalypt genera Eucalyptus & Corymbia. Composed of fused petals, this bud cap prevents the growing flower from drying out & reduces insect damage.
In contrast, Angophora species lack opercula & have rudimentary petals & sepals #LoveAGum
Get your head out of the gutter! The #ThickTrunkTuesday hashtag predates Blue Sky! But then, so do the multiple meanings, probably 😅
We like to think we're flooding the ether with more positive messaging 🌳🌱

Scientists predict fire-sensitive Alpine Ash forests could be halved in the next 60 years as too-frequent fires prevent forest regeneration.

🌳: Eucalyptus gomphocephala
Oh, we love that Weeping Mallee! We have visited it before! Isn't the arboretum (and Dean) incredible!! Great way to celebrate the diversity of eucs for Euc Day!
In the week of #NationalEucalyptDay2026, we finally got to visit #CurrencyCreekArboretum and join a good crowd in following @deannicolle1.bsky.social on a very informative tour. Photo: the beautiful form of Eucalyptus sepulcralis. When you see so many species together, their diversity is amazing.

Visiting Dean Nicholl’s eucalypt arboretum at Currency Creek SA for the 1st time - amazing collection of >800 species. #eucalypt #NationalEucalyptDay2026 🪴🌳🌱
Lignotubers can be very lumpy, but I don't know whether that is what those potato like growths are, or whether as @chenxinli2.bsky.social says they are due to a tumerous pathogen. Are the pots different eucalypt species or all the same species?
Hi! Many species of eucalypts possess a lignotuber, a woody mass of dormant buds at their base, and sprout readily, especially if their canopy is damaged. I have a few potted eucs that frequently sprout from there. findanexpert.unimelb.edu.au/news/77668-h...
The Cavendish Red Gum Festival is back from the 17th-19th of April!
Expect walks, talks and workshops galore, including a photography workshop by Georgie Mann, whose gorgeous red gum photo features in this post.

Seventy-three of Australia's 283 epiphytic orchids grow on eucalypts or other Myrtaceae. These gum-loving beauties are under threat from the expansion of myrtle rust, a fungal disease affecting their host trees.

This is incredible, Shandiya! Beautiful work!
The amazing Marri has been voted #EucalyptusoftheYear2026 🥳
This fabulous Western Australian #eucalyptus flowers en masse in the hotter months of summer providing essential resources for our native #bees and #inverts 🐞🪲🐝🦋
#ozflora #wildoz
Those Western Australians know how to mobilise voters! Nearly half of votes for #EucalyptOfTheYear2026 came from the west - #plants #trees 🍀🌾🪴🌱🌳
Great timing!! The Mugga/Red Ironbark just came third in the 2026 Eucalypt of the Year! eucalyptaustralia.org.au/eucalypt-of-...
This is a stylised landscape with the sea in the foreground, which is in shades of dark blue with ripples on it, and seven hills in shades of brown, orange, and yellow in the middle ground. The background is of a night sky, with a thin crescent moon and stars in an ascending pattern from left to right.
Happy National Eucalypt Day!

🌳 Happy National Eucalypt Day!
Today we celebrate the diversity, resilience and beauty of Australia’s iconic eucalypts, all 840 species!
Join the #NationalEucalyptDay2026 to show us how you're celebrating, ask us your gum tree questions, and tell us why you love #OurEucalyptHome!
Stay tuned to learn more about the marvellous Marri and Our Eucalypt Home on Monday, National Eucalypt Day!
Was the Marri your champion for Eucalypt of the Year? Which tree do you think should have won, and why?
eucalyptaustralia.org.au/national-euc...
With record support from Western Australian voters this year, the other nine contenders hardly stood a chance!
Rounding out third place is the rugged Mugga Ironbark, Eucalyptus sideroxylon.
The winter flowering of Mugga Ironbarks feeds critically endangered nectar nomads, the Regent Honeyeater and Swift Parrot. Mugga Ironbarks are also very popular with those pollinator powerhouses, the flying-foxes!
In second place we have that east coast darling, the Sydney Scribbly Gum, the canvas upon which the Scribbly Gum Moths make their mark!
📣ANNOUNCEMENT TIME! We are thrilled to reveal that the Marri, Corymbia calophylla, has won #EucalyptoftheYear2026!
Not only popular with people, Marri is attended by more than 80 species of native bee and is a favourite bed & breakfast for threatened black-cockatoos and possums.
