What makes a plant a perennial?
A perennial plant or simply perennial is a plant that lives more than two years. The term (per- + -ennial, “through the years”) is often used to differentiate a plant from shorter-lived annuals and biennials.
Why are some plants annuals?
Annual flowers can provide a constant source of cut flowers throughout the growing season. Furthermore, since the goal of annual flowering plants is to grow, bloom and produce seed, many, if left to mature, will produce seed for the following season.
Why are some plants annuals and others perennials?
Annual plants actually get their name because they only have a one-year life span. Perennials, on the other hand, come back year after year. Since they don’t have to be planted each year, they’re more permanent. After they bloom and produce seeds, biennial plants then die.
What is the difference between perennial and annual?
Perennial plants regrow every spring, while annual plants live for only one growing season, then die off. Perennials generally have a shorter blooming period compared to annuals, so it’s common for gardeners to use a combination of both plants in their yard.
How many years do perennials last?
The lifespan, bloom time, culture and form of perennial plants varies greatly. Some species, such as lupines and delphinium, are so called “short-lived” perennials, with a lifespan of just three or four years. Others may live as long as fifteen years, or even, in the case of peonies, a lifetime.
