Hairy beardtongue, so named because of the whiskery tip displayed by one of its five stamens, blooms in June and July. Standing on its head, a katydid nymph explores a blossom. Exploding rhododendrons set 6,286-foot Roan Mountain ablaze with color. A cousin of Scotch heather, the vivid flower takes its name from the Greek: rhodon, rose, and dendron, tree. Mountain laurel, a shrub that grows to a height of 15 feet in the Appalachians, forms virtually im penetrable thickets. Cocked stamens await an in sect's arrival; triggered by a touch, they spring up and dust the visitor with pollen. Glossy evergreen foliage can poison livestock. Bumblebees and butterflies savor a thistle's sweets along the Blue Ridge Parkway. Despite their prickly flowers, thistles belong to the same family as lettuce and chrysanthemums.
