We find that one of the original green leaf varieties called Red Prince that grows 5’ to 6’tall is a very worthy weigela to consider. Red Prince flowers around 3 weeks beginning late spring into the summer. They have bright red flowers that do not fade in color over time. It often produces a second, but sparce blooming late summer to early fall.
It is best to prune weigela annually after the flowers are spent and not to prune later when new wood is produced that will grow buds for new flowers.
