Heritage Museums and Gardens Rhododendrons Festival
Up in Cape Cod, the rhododendrons are in full bloom at the annual Heritage Museums & Gardens Rhododendrons Festival. Home to two noted hybridizers—Charles Owen Dexter and Jack Cowles—the garden is a great place to see the many new varieties in bloom. A new and dramatic water element—the Flume Fountain—and a new children's garden are also worth visiting for their unusual landcaping.
The flume fountain has a 220-foot flume with the water cascading 24 feet into a reflecting pool before being cycled back up to the top of the flume. The pool is surrounded by the daylily garden, though the garden's rhododendrons are, of course, in bloom here as well.
