Toffee Tart shifts through warm shades as the year goes on. Spring leaves open amber with a silver overlay, summer leaves turn ginger with that same silvery sheen, and by late summer they settle to green, giving the plant a changing look from season to season.
It stays low and tidy at 8 to 10 inches tall and 16 to 18 inches wide. Creamy white flowers rise on burgundy stems in early summer. It has done well in Michigan trials and is useful for brightening beds or filling out mixed containers.
What it looks like
A low, mounding plant 8 to 10 inches tall and 16 to 18 inches wide of rounded leaves. In spring the leaves are amber with a silver overlay; in summer they turn ginger caramel with a silvery sheen; in late summer they mature to green. Burgundy stems 20 to 24 inches tall carry airy sprays of tiny creamy white flowers in early summer. At peak the plant is a warm caramel mound with a light white haze on dark stems above it.
Growing it with lavender
Its warm amber and ginger tones contrast with lavender's cool gray-green in front of a bed where it gets afternoon shade and a bit more moisture.
Care
Grows in full sun to full shade. Plant in average to fertile, well-drained soil and water regularly; hardy in zones 4-9. Trim spent flower stems after bloom and tidy old leaves in spring.
