Other perennials prefer partial shade and are drought-tolerant. Whatever perennials you choose, your garden landscape can be full of flowers that bloom all summer.

In this article, you’ll find the best perennials for your front or backyard.

Do Perennial Plants Come Back Year After Year?

Most perennials come back year after year. However, depending on your climate, not all perennials can survive harsh, freezing winters. Perennials that are not cold hardy are called ‘tender perennials’ and are treated as annuals in cold climates.

To know if individual perennials flower year after year, you should check out the plant’s hardiness zone. For example, some plants sold as annuals in northern states can grow as perennials in states such as Florida, Texas, and California.

Some types of perennials can also show signs of decline. Although these plants will flower every year, you may need to replant them every three or four years. However, some hardy perennials continue to bloom annually for 20 years or more.

Tender perennials

Tender perennials are generally garden plants, shrubs, and bushes that can’t survive frost. Tender perennials typically bloom every summer in zones 10 and above. However, in colder zones, these long-blooming plants should be treated as annuals.

Half-hardy perennials

Some types of perennials are classed as half-hardy perennials. These flowers can survive outdoors in slightly colder temperatures than tender perennials. However, it’s difficult to specify exact temperatures as each plant has its own cold tolerance.
