Kirigami Deep Blue & White is a large-flowered columbine with dark indigo blue and white blooms that face upward on strong, upright stems. It flowers the first year from young plants, in late spring into early summer.
At about two feet tall, it suits borders, containers and cottage gardens, and it naturalizes beautifully in partly shaded woodland borders. The flowers last up to two weeks in a vase. Hummingbirds, bees and butterflies visit, and rabbits tend to leave it alone.
What it looks like
Large, upward-facing flowers 2.5 to 3 inches across with five dark indigo blue, pointed, petal-like sepals and long, slender, backward-sweeping blue spurs, surrounding a cup of crisp white petals and a tuft of yellow stamens. Flowers sit on upright, branching stems above the foliage. Leaves are soft green, lobed and fan-like, in a low basal mound. The plant is upright, 22 to 24 inches tall and 16 to 20 inches wide. At peak bloom many blue-and-white flowers face the sky above the mound.
Growing it with lavender
Columbine likes more moisture and some shade compared with lavender, so give it a spot in a partly shaded border or woodland edge, where it blooms in late spring before lavender begins.
Care
Grow in full sun to part shade in average, well-drained soil with regular moisture; afternoon shade extends the bloom. Hardy in USDA zones 4-9. Deadhead spent flowers to tidy the plant, or leave a few to self-sow; cut back tired foliage after bloom to get a fresh flush of leaves.
