Coral Vine, Queen’s Wreath
Polygonaceae
Deciduous, Evergreen, Vines

From Mexico. Where summers are long and hot, this tuberous-rooted perennial vine grows quickly, climbing by tendrils to 40 ft. Makes an open, airy foliage cover; leaves, 3–5 in. long, heart shaped or arrow shaped. Small pink flowers are carried in long, trailing sprays from midsummer to fall.

Evergreen in mild-winter areas; cut back vigorous growth in late winter or early spring. In frosty areas, leaves drop in fall and most of top dies, but recovery is quick when weather warms up. Where winter temperatures dip below 25°F/ –4°C, protect roots with mulch. Remove frost-killed stems from their support before new growth emerges in spring.
