Lately I and other Master Gardeners have received numerous calls about a tree that residents have seen lately, which had bright yellow flowers a short while ago, and now have developed into 2″ pinkish seed capsules.  What is it they asked?  The answer is the Golden Rain Tree, aka Koelreuteria formosa, native to Eastern Asia, but does well here also, too well.
This tree, which can get 30′ – 40′ tall, though attractive this time of year, will produce numerous seedlings in your yard, and the compound leaves can be a problem cleaning up.
While many homeowners like this tree, I would suggest you plant other trees.  In our area we have enough yard work to do, rather than add to it.
