From the late Texas plant explorer, Logan Calhoun, comes this splendid white-flowered form of the Midwest US native wine cups. Typically bearing a wine-colored flower, Callirhoe involucrata var. lineariloba 'Logan Calhoun' was selected by Logan for the large, pure white flowers on this heat-tolerant, 3' wide, clumping ground cover. For us, the white flowers top the geranium-like, cut-leaf foliage from April through July. In late summer, the clumps of Callirhoe 'Logan Calhoun' shrink back into the ground for a rest. The more hot and sunny the climate, the better wine cups perform. We still see this often listed as Callirhoe alcaeoides, which is a completely different plant!
