We had trouble growing many of the leadworts but hit upon a gem with the supposedly non-hardy Ceratostigma griffithii. After it sailed through 0 degrees F in our severe 1996 winter, we began to propagate this dynamite species. The twiggy spreading growth clothed with dime-sized, round green leaves makes a large spreading mound to 2-3' wide. In late August the clump becomes a mass of rich, pure blue flowers through autumn when the deciduous foliage takes on lovely hues of red and yellow...a favorite of butterflies, especially tiger swallowtails. In warmer climates, Ceratostigma griffithii should stay evergreen.
