Illumination® Lemon is a trailing tuberous begonia with large, double lemon-yellow flowers on cascading stems. It brings a bright seasonal display to hanging baskets and balcony containers in part shade to shade. ## Garden use and growing conditions [Proven Winners lists the named selection](https://www.provenwinners.com/plants/begonia/illumination-lemon-tuberous-begonia-begonia-x-tuberhybrida) at about 4–8 inches tall and 24–30 inches wide, with flowers in spring and summer. [Syngenta identifies Illumination Lemon](https://www.syngentaflowers.com/emea/product/flower/70083703) as a trailing Begonia tuberhybrida for hanging baskets and balcony boxes. Published width ranges differ by source, so leave room for the stems to drape. Tuberous begonias need a moist but well-drained growing medium and are vulnerable to frost. Plant outdoors after frost danger has passed; where tubers are lifted for winter, store them frost-free. The exact Proven Winners profile lists hardiness zones 9a–11b. ## Maintenance Water as the mix begins to dry, allowing excess water to drain. Proven Winners says deadheading is unnecessary; remove damaged growth and protect the tuber from freezing.
