The white form of hardy Begonia (indeed hardy in zones 6-9, but it wakes up late in the spring so be sure to mark the spot where you plant it). Where it is happy, (dappled shade and well drained soil), it will multiply and naturalize by little bulbils. Grows 18-24″ tall, with long-lasting sprays of dainty white flowers from pink buds, midsummer into fall on red stems. The foliage undersides are red.
Exposure: Sun/Part Shade
