18 Eternal Flowers That Bloom in Spring, Summer and Fall

Perennial flowers are favored for their ability to bloom season after season, sparing you the effort of replanting annually. Additionally, many perennials attract pollinators, enhancing your garden’s ecological diversity.

However, a common drawback of perennials is that their blooming period is often shorter compared to annual flowers. While some perennials may only bloom for a week or two, there are also varieties that offer extended flowering seasons.
