Sorry, no experience with these selections, though they do look great and I'm tempted to try 'Blue Kazoo'. One I would very, very highly recommend is 'Glow Girl' birchleaf spirea betulifolia. fantastic color, especially if grown in a full sun exposure with deeply dug somewhat leanish soil, fall color is an array of beautiful iridescent colors! I have three specimens around the place and they all pretty much had laughed off the very miserable winter with minimal damage. They grow thick and dense and become covered in attractive white blooms set against chartreuse foliage ... beautiful!

Thanks for the rec! Glow Girl is beautiful, I love the shape of the leaves. Only problem is, it's another gold variety! I'm hoping to get something in greener tones this year but if I do get another gold one in the future, I'll definitely remember Glow Girl! Sounds hardy.

Glad I found this thread! Can you tell me how big your Glow Girl gets to be please? FrozeBudd, in our climate, does it get to be 4' tall and wide, or is it closer to 2' x 2' x 2' please? Thanks!

Ostrich, 'Glow Girl' is a beauty, the foliage really draws the eye not just for the color, but also the texture is fantastic! It really should have been named 'GROW Girl', lol, cause yes, it can develop to a substantial and girthy thing having reached about 3 1/2 ft tall and wide, no tiny thing, also very hardy seldom having much dieback! Though, like most spirea, just prune to size or buzz it off to the ground when it becomes a bit too big, OR simply remove the older taller longer stems, Although, I'm generally not such a big fan of white blooms, it gets covered and the has a really nice classy look about it, it's a keeper in my books! Also, I love 'Double Play Big Bang' !!

Thank you, FrozeBudd!!! I am going to get myself some Glow Girls now!!! :-) Thanks!

Yes, since the time I first posted this, I decided to remove my other yellow spirea and this year I planted 2 Glow Girls. It seems very similar to my Tor spirea, which is also SO hardy and does so much better than my old spirea. And also has beautiful fall colours. I'm excited to see it do well!

That one I was asking about, Double Play Blue Kazoo, is pretty hardy I would say(but not nearly as hardy as Tor and Glow Girl). It does die back to the ground for the most part, in my garden, but it regrows much more quickly than my old spireas such as Goldflame. It also has nice colour all through the season.
