Nonstop Joy Yellow Tuberous Begonia

Nonstop Joy Yellow is a compact tuberous begonia with bright yellow flowers and green foliage. Proven Winners lists spring and summer flowering, 8–12 inches tall, and a 12–16 inch spread; the plant is used in containers and landscape beds where shade is needed. ## Cultivar and size The [Proven Winners cultivar profile](https://www.provenwinners.com/plants/begonia/nonstop-joy-yellow-tuberous-begonia-begonia-x-tuberhybrida) identifies yellow blooms, green leaves, an upright habit, and a mature range of 8–12 inches high by 12–16 inches wide. It lists USDA zones 10a–11b and classifies the plant as an annual. These ranges reflect the named cultivar and can vary with growing conditions. ## Siting Use in part shade to shade, especially in a container or a sheltered bed with loose, well-drained soil. Tuberous begonias grow best in partial shade and a loose, well-drained medium kept evenly moist; the [University of Minnesota Extension](https://extension.umn.edu/garden-and-home/yard-and-garden/gardening-in-minnesota/tuberous-begonias) notes they are not drought tolerant, and [Iowa State Extension](https://yardandgarden.extension.iastate.edu/faq/what-type-planting-site-do-tuberous-begonias-prefer) recommends shelter from strong wind and avoiding overly deep planting. In cold-winter climates they are generally treated as seasonal displays; lift and store tubers before freezing weather if you want to keep them for another year. Space plants for airflow in humid or crowded locations. ## Maintenance Keep moisture even while growing; avoid saturated soil. The cultivar profile says deadheading is not necessary. Watch for powdery mildew in crowded, humid sites and improve air movement if foliage becomes congested. In cold climates, dig and store tubers before they freeze; see [University of Minnesota Extension](https://extension.umn.edu/garden-and-home/yard-and-garden/gardening-in-minnesota/tuberous-begonias) for seasonal tuber storage practices.
