'Everblooming' bigleaf hydrangeas
Bigleaf (H. macrophylla) hydrangeas, which include varieties that can be pink or blue depending on soil conditions, are a longtime home garden favorite. And they're even better today: Many new types bloom on new and old growth, not just on last year's stems.
Among the new bigleaf hydrangeas are Endless Summer, released in 2003, and Forever & Ever, released in 2005. "They're a very romantic flower in a softer, shadier part of the garden," says Linda Guy, new products director for Novalis, a national plant company that offers several bigleaf hydrangeas.
