I love the gum trees on our property, but I only recently realised that so many of the trees ARE gum trees. I was lucky enough to pick up a book called Gum: the story of eucalypts and their champions by Ashley Hay (affiliate link), that our local library was selling off, so I only paid $2 for it, but its a great little book. I was hoping to learn about gum trees and how to identify the different types, but instead I learnt about the complicated history of the taxonomy of gum trees. Its a fascinating story, with chapters about Cook's botanist Joseph Banks, to Ferdinand Muller who continued Joseph's work and then May Gibbs, author of the gum tree baby comics and books. Apparently there are hundreds of types of gum trees in Australia (and millions of gum trees) and they are all hardwood. They are great for firewood if the wood is split and allowed to dry out. Some gum trees grow straight and tall, perfect for fence posts and building mate...
