Plant Partners for a Damp SiteBlue-flowered Camassia, clumps of sedge and Himalayan birch trees all thrive in damp soil. In a sloped bed of sedges, Camassia adds flower power, while the textured white birch bark accentuates the purple-blue flowers. "It's a combination where the components mesh well, while upping the ante for one another," says Mark Konlock, horticulture director of Wisconsin's Green Bay Botanical Garden. "Mass plantings of bulb flowers and grasses can be used to lead the viewer's eye and create a grander sense of scale."
