The backbone of a garden is perennial plants. Perennials are any type of plant that lives for several years, while annuals survive one growing season and require replanting each year. Summer blooming perennials add bright colors in the heat of the summer and are some of the hardiest plants due to their ability to withstand scorching high temperatures and lack of water.
Most summer blooming perennials die back at the end of autumn and remain dormant through winter. When the Earth warms and the days get longer, the sun helps flowering plants reemerge to showcase their blooms for the world and wildlife to appreciate.
Because these plants survive for years, you’ll save time spent outside working as well as money on buying plants every year. If those weren’t reasons enough, most perennials only require trimming and pruning once or twice a year.

Flowering Plants that Return Every Year
Hardiness is one of the most critical characteristics of summer blooming perennials. The hardiness of a plant depends on the ability to survive unfavorable weather, soil, and water conditions.
These conditions include factors such as wind, droughts, temperatures, floods, elevation, and more. Most countries are split into different hardiness zones that allow gardeners to find quick answers on a species ability to survive in their home location.
Summer blooming perennials may appear to be content in the hot summer heat, but they’ve developed adaptations that make living more tolerable.
After all, would life be considered life if everything around you were always picture-perfect? The flowers and shrubs offer gorgeous summer blooms and a fighting attitude against all of mother nature’s twists and turns.

Yarrow (Achillea millefolium)
Yarrow is a care-free plant native to North America. It is excellent to use on borders, for groundcover, or in open garden beds. It has clusters of tightly-packed, tiny flowers that come in bright yellow, pink, or red.
It is pest-resistant, drought-resistant, attracts pollinators, and makes beautiful cut flowers. Plant yarrow in the late spring or early summer.
They prefer areas with full sun, as partial sun makes it leggy. It likes hot conditions with well-draining soil. Space yarrow plants about 15 inches apart and add a layer of compost to the ground.

They are best known for their attractive, variegated foliage but blooms tall white, lavender, and pink flowers that hummingbirds love. Keep hostas in moist, well-draining soil and part-shade.
