Hydrangeas are great shade plants but often times get too large. The Let's Dance Big Easy Hydrangea is a great dwarf option, averaging two to three feet tall and wide, for those smaller spaces or large container planters. Add sulfur for blue blooms and add lime for pink blooms. Shade in the hottest part of the day will keep this shrub and its blooms looking their best. This variety blooms on both old wood and new, so you'll see a second round of flowering into the fall.
