|This 6 foot tall flowering shrub is grown for not only its showy, fragrant, fringe-like, red-violet flowers, but also its lush, copper-burgundy foliage that ages to olive-green. Perfect for large scale borders. Too often I have seen this plant used where it will either get too big for its location or will be burned back by chilling winter weather. This plant thrives in zones 8 and 9 and may do ok in warmer areas of zone 7, but no more. Soil should be moist, well-drained and acid as this plant dislikes high pH's. Sun may be either full or part-shade. Pruning is not necessary unless to remove dead branches.
