Pistachio Ambrosia has big, flat, rounded chartreuse leaves that light up shady spots, plus upright stems of light pink flowers in midsummer. It holds its color with less leaf burn and discoloration than older chartreuse types.
The mound stays 10 to 12 inches tall but spreads to about 2½ feet wide, making it a strong choice for massing under trees or anchoring a large container. Flower stems reach 28 to 32 inches and can be cut for bouquets along with the foliage.
What it looks like
A low, wide mound 10 to 12 inches tall and 28 to 32 inches across of large, flat, well-rounded leaves in bright chartreuse yellow-green. Upright stems 28 to 32 inches tall carry narrow spikes of small light pink bells in midsummer. At peak the plant is a broad, glowing lime-yellow cushion with slender pink wands standing well above it.
Growing it with lavender
This one wants shade, so plant it in a shaded bed away from the lavender, where its chartreuse leaves brighten dark foliage and ferns.
Care
Best in part to full shade; filtered light or morning sun gives the brightest color. Plant in average to fertile, well-drained soil with regular water, setting plants level with the soil surface; hardy in zones 4-9. Cut back flower stems after bloom and tidy leaves in spring.
