Its already on The List but seeing this one today in Bicton made me realise that we could probably use them more than we do.
It's Eucalyptus sideroxylon 'Rosea'….Ironbark here in the West. A good, reliable tree and very attractive with black bark, blue/grey foliage and pink flowers.
It tolerates a wide range of conditions, has good structural integrity and generally doesn't cause anyone much grief at all.
The only thing I could mark it down on is consistency. It can vary in form a bit. But that kind of goes with the territory with Eucalypts so no biggie. Best solution in my opinion is just to plant lots of them close together and you tend to lose the stragglers in the forest if you know what I mean.
