How do you tell if a plant is annual or 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. We're sharing a little bit about both types of plants below.

How do you know if a plant is biennial?

A: A biennial plant is a flowering plant that has a 2-year lifecycle. That means it takes two years for the plant to get to its flowering stage. It might seem odd to grow a biennial plant if it's only going to bloom in its second season.

Is Lavender a biennial plant?

How many years does a biennial plant have a life cycle?

What are two facts about biennial plants?
