‘Dark Horse’ is a compact, dark-leaved, pink-flowered version of the popular old fashioned weigela. It's a dense, rounded, deciduous shrub that features profuse, funnel-shaped, pink flowers (to 1.25” long) that appear singly or in clusters along the branches of the previous year’s growth in mid- to late spring, with sparse and scattered repeat bloom often occurring on new growth as the summer progresses.
