Winged Beauty, Costa Rican Butterfly Vine. Spurge family is well known for the poinsettia and other showy euphorbias, but not for its unusual vines. This is one which seems to enchant anyone who sees it. The most dramatic feature is the flowering shoots. Each has a pair of broad, pointed, reddish purple bracts, 2-3 inches long, widely spreading above and below the clustered small, whitish flowers. Outstanding sized bracts with an eye-catching show of color characterize this vigorous growing vine. Flowers year-round with its heaviest bloom in late summer. It usually recovers after light freeze.
