You may have heard of gum trees, but are you familiar with the sweet gum tree?

The term 'gum tree', is usually used in reference to trees like the eucalyptus, which have a smooth trunk  and release a thick sap. Although they do have this in common, sweet gum trees are not usually included under this very similar term...confusing!

So what does a sweetgum tree look like? Well, very different to the eucalyptus! Sweet gum tree leaves are large and star shaped, and the bark of this tree is extremely furrowed and not at all smooth. These trees are pretty spectacular to look at (check out our pictures of sweet gum trees!), however due to the spiky tree balls they grow and then promptly drop everywhere, they aren't exactly barefoot friendly.
