There are purple perennial flowers that can meet your landscaping demands, whatever they may be. The most common purple flowering perennials are discussed in this article, including qualities, features, and characteristics.

What Are Perennial Plants?

Annual plants survive one growing season and then die, whereas perennial plants survive more than two years. Throughout the spring and summer, flowering perennials develop and bloom, dying back during the winter before returning in the spring. Some flowering perennials live for just a few years, whereas others live for much longer.

Do Perennial Plants Come Back Year After Year?

Not every perennial will return each year. Some perennials are difficult to grow and perish during the harsh winter. They are classified as annuals since they only grow for one year. Tender perennials are another name for them. Year after year, certain perennial plants may reappear. They can handle the harsh cold of winter and are hardy perennials. After a harsh winter, they’ll keep returning.

Some perennial plants only bloom once in their second year, and then die. After two or three years, they will need to be replaced in this scenario. After several years, more long-lived perennial plants will require replacing, due to the decline in their vibrant growth.
