Thank you. I have a small bed and was hoping for a dwarf shrub that bloomed all through spring. I'm pairing it with a small hydrangea, which will flower in summer.

Chardonnay Deutzia from PW at least has yellow leaves, but it gets past 2ft tall. Anyone know if I could keep it at 12 to 15 inches tall with pruning?

You'd get fewer flowers cutting it back.

Chardonnay Pearls is a lovely choice. I shear mine back right after bloom to about 2 feet and it's covered in blooms.

I also have a Yuki Cherry. Got a very small one from on-line nursery fall 2015. Still a baby. Too soon to comment on blooms.

Yes, you can get good bloom for a time on older interior twigs of sheared ones - until these older stems wear out. Deutzia are what have been called "cane growers", with comparatively short lived individual stems. Successful management of these shrubs involves periodic removal of spent canes and allowing of new stems to grow to all or most of their natural shape and size, to produce a graceful specimen with an attractive natural shape. As always with plantings of any kinds of shrubs, it is much better to choose kinds that will fit within the space for a reasonable period of time than to spoil them with repeated shearing or other hard pruning intended to force them to stay within bounds.

Thank you everyone for all the great feedback. I think I'll stick with a shrub I don't have to cut back...I have so little time for gardening as it is.
