From China and Korea. Weigelas are valued for their lavish springtime display of funnel-shaped, 1-in.-long flowers. They aren’t attractive out of bloom and have no real fall color. Most are rather coarse-leafed and stiff, becoming rangy unless pruned. Use as background plants for flower borders, as summer screens, or in mixed borders.
After flowering, cut back stems that have bloomed to the side shoots that have not flowered; leave only one or two of these to each stem. Cut some of the oldest stems to the ground. Thin new suckers to a few of the most vigorous. Another method is to cut back the entire plant about halfway just after blooms fade; do this every other year. The resulting dense new growth will provide plenty of flowers the next spring.Weigela hybrids
