Giant Moonflower Morning Glory Seeds

What a delightful evening fragrance this flower has! The moonflower is a vigorous twining vine that is very fast growing in really hot weather. It is a tender tropical perennial but is now seeing popular use as an annual vine in colder areas.

Giant Moonflower is one of the most spectacular flowering vines a gardener can grow. Famous for its enormous, pure white blossoms that open dramatically at dusk, this fast-growing climber transforms fences, trellises, arbors, and pergolas into breathtaking displays of fragrant flowers throughout the summer and fall.

The large trumpet-shaped blooms can reach 5–8 inches across and unfurl in the evening, releasing a sweet fragrance that attracts night-flying pollinators such as moths. The luminous white flowers seem to glow in the moonlight, creating a magical nighttime garden display unlike any other flowering vine.

Combined with vigorous growth and heart-shaped foliage, Giant Moonflower quickly becomes a focal point in the landscape.
