Queen’s Wreath (Antigonon leptopus), also widely known as Coral Vine, is a vigorous perennial vine native to Mexico that has become a warm-season staple in Arizona gardens. Growing from persistent underground tubers, it dies back to the ground after the first frost and re-emerges each spring, sometimes producing 30 or more feet of new growth in a single summer season. Through late summer and fall it blooms profusely in dense clusters of bright pink, coral, red, or white flowers that cascade along stems and tendrils, making it a reliable source of late-season color when many other landscape plants have slowed down. Bees, butterflies, and hummingbirds actively visit the flowers throughout the bloom period, and the seeds that follow attract birds and small mammals.
From an allergy standpoint, Queen’s Wreath presents no meaningful risk. All documented sources confirm it is pollinated by insects and birds rather than wind, and no allergen proteins have been identified or characterized for the species. It does not appear in Arizona pollen panels and has not been associated with allergic rhinitis, conjunctivitis, or asthma in any documented case.
Queen’s Wreath behaves well in Arizona’s arid climate.It is best planted in full sun on a trellis, fence, ramada, or arbor where its rapid growth can fill vertical space quickly and its summer-through-fall bloom display can be enjoyed from outdoor living areas. Cut back hard in late winter or early spring to manage size and promote vigorous new growth.
