Tuberous begonias are tender and must remain frost free. For an earlier display, start the tubers in temporary pots in a greenhouse or bright, protected place from February to April, then move them outdoors once the risk of frost has passed.
Begonia boliviensis 'Santa Barbara' is one of the newest begonias to be released in the Sun Cities Collection (along with 'San Francisco' and 'Santa Cruz'). It has creamy to pure-white bell-shaped flowers, each with a yellow centre, emanating from attractive pinkish stems and salmon-pink buds. These flowers stand out magnificently against the plant’s slender, sharply pointed green leaves. Blooms start to appear in early summer, and continue coming until the first frosts of autumn!
The trailing habit of this boliviensis begonia means that it is designed for growing in containers – hanging baskets, windowboxes and patio pots – where it spills over the edges. Begonia boliviensis 'Santa Barbara' is heat- and drought-tolerant, and is perfect for giving that warm, tropical look to your garden.
Store your begonia tubers over winter and plant them again next spring to repeat your summer success year after year.

Grow begonias in light shade, protected from harsh winds. They need rich, reliably moist yet free-draining conditions. For containers, use peat-free multipurpose compost and make sure excess water can drain away easily.
Begonia tubers can be planted directly into patio containers or suitable borders in May, once frosts have passed. If planting into a border before shoots appear, mark the position so you know where to water and avoid disturbing the tuber.
Unlike pointed flower bulbs, begonia tubers are rounded with a shallow hollow on top. Plant with the hollow side facing upwards and the rounded side downwards, leaving the top of the tuber around 1–2cm below the soil or compost surface.
Space tubers approximately 15–20cm apart in container displays or 20–30cm apart in borders. This gives the developing plants enough room to form a generous, well-balanced display without becoming overcrowded.
Water after planting, then keep the compost only lightly moist while the tubers remain dormant. Once shoots appear and growth becomes established, water regularly without allowing the soil to become waterlogged or the containers to stand in water.
