From the breeder of Wine & Roses weigela comes dwarf Midnight Wine Weigela.

Midnight Wine is ideal for the front of the border or for edging the perennial bed. This tidy mound of dark burgundy-purple leaves can be used as an accent plant or a dramatic mass planting. Consider using it instead of 'Crimson Pygmy' Barberry: Midnight Wine doesn't have any thorns!  It may produce a light crop of pink flowers in spring.

Midnight Wine is maintenance free and needs no pruning because its habit is perfect the way it is. Just give it sun and water and you'll have intense color from spring to fall.
