What is the lifespan of a biennial plant?
Biennial plants have a two-year life cycle, typically forming foliage in the first year, overwintering, and then flowering and setting seeds in the second year before dying. Biannual and biennial, meanwhile, have separate meanings. Biannual” means occurring twice in one year, and “biennial” means happening once every two years.A biennial requires all or part of two years to complete its life cycle. During the first season, it produces vegetative structures (leaves) and food storage organs. The plant overwinters and then produces flowers, fruit and seeds during its second season.
What plants will come back every year?
Perennials are a flower garden’s backbone, providing beautiful color, texture and form. They are easy-care, dependable performers that come back every year. Perennials are a diverse group of plants that includes flowering plants, shrubs, and trees. Most garden perennials are herbaceous and die back before winter, but you’ll also find woody and semi-woody perennials that don’t die back. Perennials can also be categorized as hardy or tender.Perennial plants are those with a lifespan that lasts at least three years, though they can live significantly longer as well. Perennial foliage may die back during the winter months but will regrow from dormant roots the next season.
