If you need to add a punch of color to a summer shade planter or hanging basket, consider the Nonstop series of tuberous begonias. Huge double-petaled flowers bloom almost continuously from late spring right up until freeze, requiring morning sun and afternoon shade or all-day filtered sun for best results. 'Nonstop Red' adds drama to container planters or hanging baskets when paired with other shade loving annuals or perennials. Keep these begonias healthy and disease-free by removing spent blooms and damaged foliage, and water below the leaves when possible, as excessive moisture can cause powdery mildew. 'Nonstop Red' begonias form an upright compact mound, about a foot tall and wide, with fleshy, almost succulent-like leaves, adding to the lushness of these shade-loving annuals.
