Rubies and Diamonds is an alpine bleeding heart with long-lasting ruby-red flowers over finely textured, glaucous blue foliage. It is a strong choice to anchor the front of a sunny border.
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 12 to 14 inches tall and 16 to 18 inches wide of very finely cut, lacy, fern-like leaves in glaucous blue with a soft, powdery bloom. Small, puffy, heart-shaped flowers about three-quarters of an inch long are rich ruby red with slightly paler 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 enjoys sun and drainage like lavender, and its ruby hearts over blue foliage make a rich accent in front of 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.
