I've never seen that tree before, but it's probably not indigenous to Michigan :)It was much prettier covered with flowers :)
Here you go mom. This is your mystery treehttp://en.wikipedia.org/wiki/Acacia_dealbata
Kim wins the prize for identifiying this tree. It is an Acacia dealbata or(Silver Wattle) and is native to Australia. I wonder how it ended up in the graveyard in Vacaville, Ca.By the way,Kim, the prize is a visit from me and Dad in July. LOL.
Fun to see this in different stages mom! :)
