H4 in. x W6 in. This obscure hybrid columbine is well-known among enthusiasts as an easier alternative to the exquisite but recalcitrant parent, A. jonesii. Small mounds of ferny, glabrous foliage bloom in summer with pale blue flowers with white-tipped spurs. Perfect in a trough, in gritty, lean soil and light shade from hot sun. Hardy to Zone 3.
