Apple Twist is a coral bells grown for foliage that changes through the season. New leaves come up chartreuse yellow with red veins, and as they mature the veining fades and the leaves shift to a fresh apple green.
The wavy, rippled leaves form a dense, full mound about a foot tall and up to two feet wide. It is a natural for edging shady paths and filling containers, and the evergreen foliage adds color well into the cold months.
What it looks like
Rounded, lobed leaves 3 to 4 inches across with wavy, rippled edges; new leaves are bright chartreuse yellow with red veins, and older leaves mature to apple green with the veining fading. The leaves overlap densely on short stems to form a low, full mound 10 to 12 inches tall and 20 to 24 inches wide. In midsummer thin, wiry flower stems rise to about 18 to 20 inches with sprays of tiny bell-shaped flowers. At its best in late spring the mound shows a mix of glowing chartreuse leaves with red veining and softer apple green leaves.
Growing it with lavender
Coral bells prefer shade and richer, evenly moist soil, so place this one in a shady bed or container away from the lavender, where its chartreuse leaves can light up a dim corner.
Care
Grow in part to full shade in humus-rich, well-drained soil kept evenly moist; soggy winter soil causes crown rot. Hardy in zones 4 to 9. Trim off tattered leaves in early spring, and replant or mulch any crowns that heave out of the ground over winter.
