Bush honeysuckles, in the genus Diervilla, are small native American shrubs that are not the same as the weedy honeysuckles in the genus Lonicera, but they are related to weigelas. They can be recognized the opposite, toothed leaves along slender twigs and clusters of tubular yellow flowers with long stamens and pistils protruding from the flowers. ‘Butterfly' is very floriferous. Because the sets of leaves are spaced so closely towards the ends of the branches, the axillary and terminal clusters of flowers can number up to 50 florets, with an extended bloom period. Overall, the foliage is dark green, but new leaves are brushed with bronze and have a fine picotee of red. Fall color is reddish-purple. Bush honeysuckles, native to dry woods and clearings, are adaptable to many soils, and will grow in sun or partial shade. They bloom starting June, and continue sporadically until September. New growth is tinged red.
