Begonias tend to be leggy. Pinch the tip of branches to promote lateral growth. Begonias growing indoors should be moved to a partly sunny location outdoors during the summer. Some begonias do not tolerate direct sunlight and should be placed in the shade. More information on moving plants indoors and outdoors is available in Indoor Plants - Moving Plants Indoors and Outdoors , HGIC 1454.
Most foliage begonias grow from thick rhizomes that grow along or just beneath the soil surface.
The growth habit is generally bushy or trailing, but there are a few tall foliage begonias. Leaf size, shape and texture are varied. Foliage begonias flower in midwinter to late spring. Flowers may be hidden in the foliage, just above it or on long stems above the foliage. Rex begonia hybrids may be the most striking of all foliage begonias.
