Notes: Moonflower is a stunning, night-blooming vine that captivates gardeners with its large, fragrant white flowers that open in the evening. It is a close relative of the morning glory, with similar heart-shaped leaves and climbing habits, but its blooms add a unique nocturnal charm to the garden.

Moonflower is ideal for trellises, fences, and arbors, where it can create a lush, romantic look while providing evening interest. The plant thrives in warm, sunny locations with consistent watering and occasional fertilization. While it is easy to grow, its vigorous growth habit may require regular pruning to keep it in check.

This vine is a favorite in moon gardens, where its luminous flowers stand out against the darkness and release a sweet fragrance. Its unique blooms and low-maintenance nature make it a popular choice for gardeners seeking to add elegance and evening allure to their landscapes.
