Begonia grandis subsp. evansiana var. alba (Hardy Begonia) is a tuberous perennial boasting long-lasting sprays of dainty white flowers, 1 in. across (2-3 cm), from midsummer to early fall. Borne on branching red stems, they rise atop the foliage clump of large, obliquely ovate, olive-green leaves, adorned with reddish undersides. Slow-sprouting, this shade-loving perennial forms a bushy mound that mixes well with hostas and ferns in the shade garden. A desirable begonia variety helping to brighten dark corners.

  • Prefers partial shade to full shade and organically rich, moist, and well-drained soils. Will not tolerate waterlogging. Mulch to protect roots.
