Comstock Knoll’s unique topography was created by glacial activity and flowing water. The knoll is ablaze in May and early June with the vibrant white, yellow, pink, and red blossoms of the Bowers’ Rhododendron Collection. Rhododendrons and azaleas are interspersed with small flowering trees, ferns, and perennials—including an extensive Hosta collection—all shaded by century-old white pine trees.
