Limitless™ Dark Red Begonia

Limitless™ Dark Red is a tuberous begonia selected for extra-large, fully double red flowers held above a compact, well-branched mound. The plant is part of Syngenta Flowers’ Limitless series and is suited to small containers, larger patio pots, and hanging-basket production. ## Form and season [The breeder lists the cultivar](https://www.syngentaflowers-us.com/product/flower/70089787) at about 20–25 cm tall and wide, with flowers from early spring through summer. Its habit is upright and mounding, and its recommended exposure is partial shade to full shade. Syngenta lists it as an annual and gives a hardiness range of USDA 10a–11b; gardeners in colder areas should plan for seasonal replacement or frost-free tuber storage rather than assume outdoor winter survival. Tuberous begonias bring color to containers and bedding. [The Royal Horticultural Society recommends](https://www.rhs.org.uk/plants/begonias/outdoors) planting outdoors after frost danger has passed and regular watering during dry periods. A sheltered position with filtered light is helpful in hot weather. ## Maintenance Plant in a draining medium and water regularly while growth is active, keeping the root zone moist rather than saturated. Remove damaged leaves and maintain airflow around the foliage. Before frost, either discard the seasonal plant or lift the tuber for dry, frost-free storage until spring.
