List of White Perennial Flowers

Updated April 17, 2017

White flowering perennials are the vanilla ice cream of the horticultural world. They fit in perfectly almost anywhere. They add softness to vibrant reds, oranges and yellows, while complementing the coolness of blues and purples, creating a feeling of tranquillity. An all-white flowering garden generates serenity and a feeling of purity. Pair them with the white and green variegated leaves of plants, such as hostas, and watch that shaded nook brighten up immediately.

Shasta Daisy

There is just something about the perky daisy-style perennial that adds an element of whimsy and fun to a garden. Leucanthemum is a variety of chrysanthemum, some of which are perennials, some annuals. The leucanthemum superbum is commonly called the Shasta Daisy and is a robust perennial with glossy green leaves. Depending upon the variety, it can sport single or double, white flower heads. These daisies grow to about 3 feet tall and are excellent as cut flowers. They prefer full sun and can get a bit leggy, requiring some support if they don't get sufficient sun exposure.


Clematis is an elegant flowering climber, well-suited for trellises, scaling fences or even wrapping around other climbers without compromising them. Clematis comes in many varieties, with both white and coloured flowers. Depending on the variety, they’ll bloom in late spring, throughout the summer or even in autumn. Clematis grows easily. Most starter plants are about 8 to 12 inches high and are a bit fragile, so it’s best to be cautious when planting to avoid breaking off any stems. They prefer a shady spot for the lower part of the plant but delight in full sun as they get taller, making them wonderful choices to entwine around vining plants like euonymus or climbing roses. If training it to climb upward, plant it at a slight angle so the head of the plant is reaching back toward the fence or trellis. Among the numerous white-flowered varieties are “Silver Moon,” “Alba Luxurians,” Clematis armandii, “Sieboldii,” “Gillian Blades” and “Henryi.”

Snow in Summer

Cerastium tomentosum, or as it’s commonly called, Snow in Summer, is a low-growing, mat-forming, creeping perennial, typically only 2 to 3 inches tall, that’s just perfect spilling over the tops of stone walls or tumbling down berms. It bears silvery-green, fuzzy, narrow leaves and is carpeted with petite star-shaped white flowers; hence its name, as it gives the appearance of a light snow having fallen on the summer grass. It is fast-growing and spreads suitably to use as a ground cover in full sun, survives in poor soil and is useful on dry, sunny banks. It’s best suited for areas where it can free flow, rather than tiny formal gardens where its enthusiastic growing habit would require constant maintenance.
