Sun King is a bold foliage perennial with large, bright gold leaves on reddish brown stems. With a few hours of sun each day the leaves stay golden all summer; in deeper shade they turn chartreuse to lime green, still brightening dark corners.
It quickly grows into a big, shrub-like clump about four feet tall and wide, sometimes reaching six feet, dying back to the ground in winter. In mid to late summer, spikes of tiny white flowers attract honeybees and are followed by dark purple-black berries that are not edible. It is a great companion for hostas and other woodland plants and is remarkably resistant to deer.
What it looks like
Very large compound leaves up to 3 feet long, divided into many oval, pointed leaflets 3 to 6 inches long in bright golden yellow, carried on thick reddish brown stems. In mid to late summer, upright branched spikes of tiny white flowers rise above the leaves, later followed by small round purple-black berries. The plant is a bold, shrub-like clump about 4 feet tall and wide when established, up to 6 feet tall with age. At its best the whole clump glows gold in partial shade.
Growing it with lavender
Sun King needs moist, rich soil and part shade, so it belongs in a woodland or shade garden with hostas and ferns rather than in a sunny lavender bed.
Care
Plant in part shade in rich, deep, organic soil that stays moist but drains well; it is not drought tolerant. Hardy in USDA zones 3-9. A few hours of sun keeps the leaves gold; cut stems to the ground after frost, and give it plenty of room to spread.
