Begonia Nautilus Lilac has eye-catching appeal for an indoor or outdoor container. Each rounded leaf has a showy swirl in the center and colorful foliage in tones of lilac, rose and silver with black trim at the leaf edges and green veins. It has an upright growth habit and needs full shade when grown in outdoor gardens. As a houseplant, grow in partial sunlight and let the soil dry out between waterings. Flowers appear intermittently throughout the year.
