A collage of some of the prettiest perennial flowers.

When it comes to starting a garden or other landscape project, perennials are a great option because they keep coming back year after year. There are a seemingly unlimited numbers of options out there so narrowing it down can be tough. Check out our list of the prettiest perennial flowers.

Whether your a lifelong gardening enthusiast or you’re just honing your green thumb, the numbers of flower and plant options out there can seem overwhelming. Perennial flowers are popular among all types of gardeners because they keep coming back every year, often larger and more vibrant than before.

While it’s tough to find an ugly flower, it’s possible to choose flowers that don’t fit your climate, soil conditions, or space limitations. It’s also possible to select flower combinations that don’t mix well together, whether because one attempts to take over the territory of the other or because their soil and watering needs are not the same.

To cultivate a flourishing garden you’ll need to do plenty of research and understand the types of conditions you’re working with, including the amount of sun and water to expect, the pH levels of your soil, and your own tolerance for regular tending and care of your plants.

Once you understand your garden you can choose flowers that fit those conditions. Rest assured that no matter the conditions, there will be plenty of beautiful choices to bring you joy and make visitors envious. We broke down thirty of the prettiest perennial flowers to help you get a list going.
