A chance seedling here from C. moellendorffii but assuredly a hybrid, with the palest pink fading to white sepals and flowers. Long ago Heronswood once - once- offered a white flowered C. alternifolia. I stupidly didn’t order it, and it quickly disappeared into private gardens, never to be seen in commerce again, so I was especially thrilled to “find” this plant. 24-30” high by about the same wide, flowering summer into late summer. Shade/pt shade, even moisture, good drainage. Easy, as moellendorfii is perhaps the most durable species in the genus. Z5?, quart pot
