Begonia maculata 'Wightii' (C)
begonia 'Wightii'
A vigorous tender perennial with long and narrow green leaves revealing crimson red undersides and covered in silvery white polkadots. Clusters of pinkish, greenish-white flowers with yellow centres appear between January and December. Although this variety prefers a warm spot on a windowsill or in a greenhouse, care should be taken not to place the plant directly in hot sunlight, to avoid leaf scorch.
