Wine and Roses Weigela is known to equally attract hummingbirds and gardeners. Hummingbirds love the deep rose-colored tubular flowers, while people are attracted to the polished dark purple, almost black, foliage underneath the flowers. Wine and Roses Weigela will bloom off and on throughout the summer and quite heavily in the spring. The branches, with or without flowers, can be used in floral arrangements. Full sun will provide the best flower and foliage color. This will grow well up to USDA Zone 4 and takes medium water in a well-drained soil.
