I planted my Shibori last spring, and while it was a small plant it grew nicely and is a lovely rounded shrub about 30 x 30" .... just right........but as others have stated I am a bit disappointed as the color of the flowers are only pink and a lighter pink, no white or red.
Still, it has not required any pampering, and seems , like my other spireas, to be a hardy and reliable little shrub. I like it even though there arent 3 colors... It has been blooming constantly since June.
This is an attractive, easy, trouble-free plant. There seems to be some lack of three-coloredness in the cultivar, though. I bought 3 plants from a catalog some years back, and only one of them shows multiple colors. I'm guessing that if a cutting is taken from an all-pink branch, all-pink plants result. Might be worthwhile to stick to in-bloom plants from a garden center.

Twiggy small shrub (2' by 2') with loads of flattened flower cymes of near white, pale pink and medium pink, all at the same time. Mine has been in place for six years, part shade, no problems. I trim off the spent flowerheads in early winter. This encourages bushier growth and also prevents ugly brown clusters from hanging around through the next season.

Received mine in spring 05 in 8-10" pot. By summer 05 it was about 20"x20" shrub and bloomed extensively over an extended period. However, while vendor's pic shows white, pink, and red blooms all on the same plant, all of the blooms on mine ranged from pale to med pink. Appears to be easy to grow and somewhat drought resistant.
Edited to add that I recently read an article which indicated that Japanese Spirea (not specific to this variety) may be invasive. So far I have not seen any indication of this, but wanted to add this cautionary note.
