Description Also known as Sunset Bells, this beautiful plant is so easy to plant and grow, coming back each Spring to greet you. This plant starts with dark purple foliage that turns a coppery color with age, leaving the underside of the leaves a beautiful shade of purple. The flowers emerge almost immediately after breaking dormancy in the Spring and continue to bloom until the plant falls dormant in the fall. Very easy to grow, they do best in bright shade but grows in both full sun and deep shade.. In direct heat, the edges of the leaves burn, and in deep shade they grow tall and leggy, so find a happy medium- they are not too picky. They prefer evenly moist, well draining soil, and little to no water when they have gone dormant.
