Limitless™ Sunset Begonia

Limitless™ Sunset is a compact tuberous begonia in Syngenta’s Limitless™ series, bred for large double flowers held above the foliage. Its Sunset selection adds a warm seasonal accent to the series’ double flowers. Its mounding, upright growth and early-to-summer flowering suit containers, window boxes and sheltered shade plantings. ## Series and size The [Syngenta Flowers product profile](https://www.syngentaflowers.com/ams/product/flower/70089783) identifies Limitless Sunset as Begonia tuberhybrida and gives a mature garden size of 8–10 inches high and wide. The breeder describes a compact-to-medium, mounding and upright habit, with fully double, extra-large flowers displayed above the leaves. Its product listing gives flowering from early spring through summer and recommends full or partial shade. Plants grown from tubers or seed may vary with culture and climate; treat the listed size as a garden range rather than a fixed point. ## Siting and seasonal use Grow in bright shade or partial shade, protected from hot afternoon sun and strong wind. [University of Minnesota Extension](https://extension.umn.edu/garden-and-home/yard-and-garden/gardening-in-minnesota/tuberous-begonias) recommends a sheltered site with well-drained soil and regular watering; tuberous begonias are not drought tolerant. [Iowa State University Extension](https://yardandgarden.extension.iastate.edu/faq/what-type-planting-site-do-tuberous-begonias-prefer) likewise recommends moist, well-drained soil and partial shade. Use a porous container mix, and allow drainage so water does not collect around the tuber. These tender plants are typically grown as warm-season annuals in cold-winter areas; in suitable climates, tubers can be lifted and stored indoors through dormancy. ## Maintenance Keep the root zone evenly moist without leaving the pot waterlogged, and feed lightly during active growth according to the fertilizer label. Remove faded blooms and yellowing leaves to keep the display tidy. Before frost in cold climates, reduce watering as growth declines, lift and dry the tubers, then store them in a cool, dark, dry place until late winter. Avoid overwatering dormant tubers because they can rot.
