Viola walteri 'Silver Gem' (Walter's Violet)
This compact violet is an enchanting groundcover with beautiful silvery-blue, heart-shaped foliage. Throughout spring and early summer, small violet flowers protrude from beneath the foliage. A single plant reaches about 3″ to 5″ tall and spreads as much as 10″ to 15″ wide. It is ideal for shady woodland settings but once established, it is very drought tolerant.
