Gardens are always a work in progress, so if you're looking for a way to add a sense of timelessness to your design, consider planting white flowers. Many white flowers are perennial, so you plant them once and enjoy them for years. White flowers can add a dreamy glow to your landscape at night, so they’re a necessity in moon gardens. Consider interplanting them in mixed borders, or transform an entire section of your garden into a peaceful oasis by planting only white flowers and white flowering shrubs.
