Annuals, Perennials, Shrubs, Flowers
Grown for textured, multicolored foliage, saucer-size flowers, or lacy clusters of smaller blooms.
Grow as perennials in Zones 14–24, H1, and H2, except as noted. Can also be grown as annuals anywhere or dug and stored. Outdoors, most grow best in pots in the ground or in hanging baskets in filtered shade, with rich, porous, fast-draining soil, consistent but light feeding, and enough water to keep soil moist but not soggy. Most thrive as indoor plants, in a greenhouse, or under a lath. Some prefer terrarium conditions. Almost all require at least moderate humidity. In areas with hot, dry summers or indoors in winter, set pots in pebble-lined saucers or trays kept filled with water to below pot level.
Most are easily propagated from leaf, stem, or rhizome cuttings. They also grow from dust-fine seed. Of the many hundreds of species and varieties, relatively few are sold widely.
These have stems that trail or climb, depending on how you train them. They bloom sporadically during warm weather and are well suited to hanging basket culture or planting in the ground where well protected. They need conditions similar to those for tuberous begonias, though trailing types are not lifted for storage. Examples include hybrid ‘Potpourri’, with strongly scented deep pink flowers, and one of its parents, B. solananthera, with glossy light green leaves and fragrant white flowers with red centers. B. glabra has trailing stems to 3 ft. long, with heart-shaped, bright green leaves and profuse white flowers in winter and spring.
