Few shrubs inspire as much devotion—or as many questions—as hydrangeas. Richie Steffen, executive director of the Miller Garden in Seattle, who has grown too many hydrangeas to count, shares his personal favorites from this beloved genus, from classic mopheads and lacecaps to oakleafs, panicles, and lesser-known species worth seeking out.
Along the way, he’ll demystify the issues that trip up even experienced gardeners: when and how to prune each type, managing flower color, siting, and watering. And, as a bonus, Richie will share his insights into which hydrangea cultivars have the best blossom and foliage color in fall. If you thought you knew everything there was to know about hydrangeas, this class might surprise you!
