These long-lasting flowers are perfect for creating vibrant and lively landscapes. From vibrant coneflowers to tickseed, creeping phlox, and fragrant lavender, there are a variety of perennials that will bloom for several weeks, starting from late spring or early summer.

Descriptions and pictures of these long-blooming perennial flowers will help you select the perfect plants to keep your garden blooming from spring to fall. Additionally, you will learn helpful tips on how to care for these perennials for optimal growth and longevity.

What Are Perennial Flowers that Bloom Throughout the Summer?

Perennials are plants with a life cycle lasting for more than two years. Unlike annuals—which complete their life cycle within one year—perennials can live for multiple growing seasons. They can regrow and bloom again year after year, even after going through periods of dormancy during colder months.

Perennial flowers, shrubs, and herbs that bloom from spring to fall are excellent for low-maintenance garden landscapes. Once established, long-blooming perennials require less effort to maintain, compared to annuals, as you do not need to replant them annually.

In this list of perennial flowers that bloom throughout the summer, it’s good to remember that some flowers only grow as perennials in warmer climates. In cooler climates, the long-lasting flowers—called tender perennials—may grow as annuals because they don’t survive harsh winter conditions.

Therefore, check the growing zone before choosing a perennial to fill your front or backyard with color all through the summertime.
