What does it mean when a plant is perennial?
Perennial Plants
Perennials are plants that can live for three or more growing seasons (oftentimes, especially in St. Louis, bulbs must be planted in autumn to produce spring-blooming plants).
What is the difference between an annual and a perennial?
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.
Do perennials spread?
Fast spreading perennials fill in gaps in your landscape and flower gardens quickly. Once established, these types of perennials crowd out weeds, so they reduce the need to weed the garden constantly. Fast growing flowers add color to the garden during the same year they are planted.

When should I plant perennials?
Technically, you can plant perennials any time your soil is workable. Practically, the best times to plant perennials are spring or fall. These seasons allow plants to get settled and grow new roots before summer's hot, dry weather arrives. Planting in summer is okay, but you'll need to water frequently.
