While they may not be as showy as vibrant-hued florals, white flowers are uniquely dynamic and special in their own right. Plants with white blooms lend a cooling effect to gardens, especially on hot summer days, and they practically glow in the evening. Pairing white flowers with other plants is an effortless task, as they look seamless in combination with any other color of blossoms or foliage. And on their own in an all-white landscape, white flowers stun with their classic, timeless, elegant beauty. There are many ways to add a tranquil touch to your garden, and these showstopping plants with white flowers are a magnificent way to do so.

Japanese Anemone
A great cut flower for the fall garden, Japanese anemone (Anemone spp.) produces cup-shaped blooms of pink and white petals. It's known for its tendency to spread, so plant it where it has plenty of room to grow. Anemones make great companions for goldenrods and tall varieties of aster.

Lilac
You don’t have to rely on only annuals and perennials for beautiful flowers. Many shrubs—including lilac (Syringa spp.)—also offer lovely white blooms.

Size: Up to 20 or more feet tall and wide
Zones: 3-8
Calla Lily
Another favorite cut flower, calla lily (Zantedeschia spp.) is a tender plant with elegant, vase-shaped flowers.

Callas look stunning with the full flowers of double dahlias, and they gorgeously accent the tropical aesthetic of dwarf varieties of canna lily.
Growing Conditions: Full sun and moist soil

Size: Up to 30 feet tall

Using White Flowers in a Moon Garden
White flowers are undoubtedly gorgeous for daytime viewing, but they're spectacularly unique at night under the moon's glow. Many gardeners use flowering tobacco, gardenia, mock orange, and other white flowers in moon garden designs because of their mesmerizing ability to reflect moonlight.
The beauty of white flowers shines on its own, but the bright blooms are further emphasized in a moon garden with strategic lighting, silvery foliage, and other design features.
