Whether you're planting a small garden, decorating the backyard or boosting your curb appeal, colorful flowers are the finishing touch your outdoor space needs. While there are thousands of varieties to choose from, the best perennial flowers require very little care and provide years of beautiful blooms. While some flowers, like tulips, may return for only a few years, others (think peonies and hydrangeas) will pop up for decades, possibly even a century.
Here, we've rounded up the best perennials, complete with zone requirements, sunlight needs and optimal blooming times. Unlike annual flowers (plants that complete their life cycle in a single year), perennials come back year after year — so you don't have to worry about reseeding or replanting every spring. Some perennials, like daffodils and phlox, bloom in early spring, while fall flowers, like allium or summer lilacs, may bloom well into September. Meanwhile, a few of our favorite summer blossoms include sage, aster and lavender flowers (hint: some leaves are great for making tea).
The only downside? Most perennials have a relatively short bloom season, which ranges from a few days to a few weeks. For this reason, most gardeners choose to interplant perennials with annuals, so a well-designed backyard looks colorful year-round. We've rounded up flowers of nearly every shade, including white, yellow, purple, pink, blue, red and orange — so you're sure to find a plant that fits your style. You'll even spot some easy-to-grow flowers, including Baby's Breath. And if the flower's meaning is important to you, we've sprinkled in plenty of pretty options with symbolic meanings.

These low-maintenance plants are commonly referred to as Blue Star flowers — obviously due to their periwinkle blue, star-shaped flowers that bloom in clusters.

Hostas
Bring a tropical look to your garden with this low-maintenance foliage, which comes in a variety of green shades with white or purple flowers during summer or fall.

Otherwise, they're fairly tolerant and can live for decades if properly cared for.

Achillea (Yarrow)
This hardy and versatile perennial is as carefree as it gets: Yarrow is pest-resistant, quick to spread and a major pollinator. Since it grows quickly, use it as ground cover, or to fill open meadows or large spaces. Once the red, yellow, pink or white flowers bloom, cut them (a.k.a. deadhead) when their color starts to fade to encourage more flowers to grow.
Zones 3-9; prefers full sun; blooms summer
