I have a Lime Rickey that looks promising. Will post pics when that blooms within a month. People have had mixed results with Incrediball as well, but mine have seemed fine enough.

Lime Rickey looks like a great smooth hydrangea. I'd definitely be interested to hear how it does this year for ya. I'm also in 6b.

After several starts I finally have two Hayes rooting. Will post if they make it. Some Hydrangeas really don't want to root but you have to keep trying - and have a very understanding friend with the mother plants. lol

Here's my Lime Rickey. Quietly grows to 4x4, so far. Mine is out in the open and gets sun from noon-7. Does NOT flop in the rain. It's no more white or green than any Annabelle, Incrediball, etc. and the blooms are relatively small. I don't like it much where it is so I may move it to a shadier spot (please disregard Everlasting Pearl in the foreground).
