Moonflower (Ipomoea alba) is a unique member of the morning glory family in that it blooms at night. The white flowers are about 5 inches across and they almost seem to glow in the moonlight. That large size combined with their appealing aroma helps attract nocturnal pollinators.
Native to Florida the vine also sports showy, heart-shaped leaves. I’d love to have one in my yard but I don’t have anywhere for it to grow, they need support and can reach 40′ in length. The flower I photographed was on a vine that was at least that long since it had grown up and over a telephone pole. What a beaut!
