The plantation here has been planted with Blue Gum trees.
Although the tree itself has a pale trunk the Blue gum refers to the juvenile foliage which can have a dull greyish-green almost pale blue hue about it.
The flowers of the blue gum can vary in colour, from cream to pink to even deep red. Their nectar and pollen are much sought after by birds, native bees, insects and possums.
Don't be fooled. I spy a Blue Gum but this is not where the cache is.
No need to enter the property.
Good Luck!
