A low-growing, mounding perennial known for its profusion of white, upward-facing, bell-shaped flowers that bloom from late spring through late summer. It forms a cushion of small, heart-shaped, dark green leaves and is a compact plant, reaching a height of 15-20 cm (6-8 inches). This variety is a vigorous and earlier-blooming cultivar, making it ideal for rock gardens, borders, containers, and as a groundcover.
