My favorite kind of tree is the Ginkgo. Someday, I will have one in my backyard. Perhaps with some bamboo friends to keep it company while I am at work (bamboo being my favorite woody perennial evergreen plant in the true grass family (thank you Wikipedia)).
Late last year, I discovered a Ginkgo in Riverfront Park. It is now my very bestest secret tree friend. Or, at the very least, a tree I say hi to whenever I walk by. It is only just starting to show green leaf buds right now, but I'll save that for a later ginkgo update (as none of the pictures I took today were worth publishing).
