White Diamonds is a sun-tolerant alpine bleeding heart with pure white flowers from spring until frost over fine, glaucous blue-green foliage.
Unlike the classic shade-loving bleeding heart, this alpine type prefers sun and sharp drainage and does not go dormant in summer. It blooms from late spring into fall, with a peak in early summer, and fits well at the front of a border, in rock gardens and in containers.
What it looks like
A tidy, rounded clump about 14 to 16 inches tall and 16 to 20 inches wide of very finely cut, lacy, fern-like leaves in blue-green with a soft, powdery bloom. Small, puffy, heart-shaped flowers about three-quarters of an inch long are pure white with a faint cream tint at the tips. The flowers dangle in small clusters from slender, arching stems held just above the foliage. At peak bloom in early summer the lacy mound is topped with many little hanging hearts.
Growing it with lavender
It likes lavender's sun and good drainage, and its white hearts and blue lacy leaves make a cool, fine-textured companion for lavender.
Care
Plant in full sun to light part shade in average soil with excellent drainage; this alpine type does not want a shady, damp woodland spot. Hardy in zones 3-9. Water during long dry spells, and trim off tired foliage in midsummer if needed to refresh the plant.
