I selected this seedling about 8 years ago and its been growing in my garden for all that time. A completely deciduous variety that does not show leaves until all chance of frost has passed. Forms a large clump with strappy arching green leaves – to 2′ across in 5 years. As the clump increases so do the amount of flower stalks. The orbs of flowers are neon to cobalt blue. An arresting, glowing blue. Slightly smaller in diameter than other varieties (about the size of a baseball) this plant packs a LOT of flowers onto a stalk- at least 50 and they reverberate above the clump for weeks in July to August. To 26″ in bloom. The stalks that support the vivid flowers are incredibly strong and they barely bend in a breeze. This is a wonderful perennial for full sun and rich, amended soil. Add a handful of lime at planting time to ensure neutral pH. Disappears cleanly in winter. Regular water though its bloom cycle. Pair with chartreuse foliage for a dynamic contrast. Loved by hummingbirds and bees. Best in the center of an ascending border from low plants to tall. Long lived, cold hardy selection that we love.
