An interesting eucalypt species from both a timber production perspective but also an ornamental point of view, Corymbia maculata (known as Eucalyptus maculata from 1844 to 1995) sets its flower buds and later its seed capsules in panicles also known as corymbs. Individual flowers and capsules are normally grouped in 3's or 4's, but many times a pair of groups grow from the same point of the branchlet, giving appeareance of groups of 7's. Globose and urn shaped capsules of medium size normally develop in dense clusters where previously medium sized white flowers attract nectar browsing fauna that involuntarily cooperate with this eucalypt for pollination.

We include it in category EUCF (absolute minima from 0ºC to -5ºC) for safe cultivation, but suitable seed provenances from mid to high elevations in the inland ranges of Victoria or Southern NSW could show a bit higher tolerance to cold, so it could be tried with caution in the mildest part of ATL1 zone (absolute minima from -5ºC to -10ºC). In our experience it can survive temperatures as low as -7ºC, but losing its yearly growth to later resprout from lignotuber, so not easily achieving tree size. A very high amount of plant losses happens when temperatures approach -10ºC. Safe zone is then around -5ºC.
In Galicia (Northwestern Spain) it is cultivated infrequently, wich is a shame, and best specimens are always present in coastal areas corresponding to USDA Zone 9.
