I ordered 24 Eucalyptus Deglupta (rainbow gum) for 3.69. It is a beautiful tree with rainbow colored peeling bark. I've grown two seedlings before but they died due to neglect that was because of depression.

They germinate easily.
I going to use them for bonsai and I haven't decided whether I doing a single tree in a pot, a group planting, or both.

That will make a really gorgeous bonsai tree, Adam. If you grow just a single one, it maybe will make a bigger trunk as you keep trimming it, and show off its pretty bark colors.

Here's pictures of one I saw at the botanical garden in Gr. Cayman a couple of years ago. They get really large!
