Annual & Biennial Flowers & Plants

Annual plants complete their growth cycle over one season, meaning they grow and die within one season in one year. 

Biennial flowers and plants complete their growth cycle over two seasons, meaning they take two years to complete their cycle from seed to death. 

Gardeners may plant annual or biennial flowers and plants for different times of the year to create a year round visual display of colours and shapes in their outdoor space. They may then need to replace the seeds to replicate the experience. 

Commercial landscapers and gardeners may use annual and biennial flowers and plants to plan a timed growth display in a communal space.

Biennial Flowers & Plants

Biennials need two years to complete a life cycle, with their first season of growing involving a simple set of leaves near soil level. 

During the second season the plant then grows a stem, flowers and seeds before dying completely. 

Garden owners would need to replant the seeds after year two to then start the two-year cycle again. They may also plant the seeds during year one to continue the cycle without any breaks.

Types Of Annual & Biennial Flowers & Plants

Annual and biennial flowers and plants are available in a wide variety, including:

  • Primula Wanda
  • Viola
  • Pansy
  • Carnation
  • Geranium
  • Petunia
  • Creeping Jenny
  • Dwarf Foxgloves

Planting and Maintaining Annual & Biennial Flowers

The planting, maintenance and removal of annual and biennial flowers should be completed according to the manufacturer's instructions on the packaging of the plant or plant seeds. 

In all cases, the success of the plant’s growth is subject to the grower’s experience, weather conditions, soil condition, maintenance and garden suitability.

The Benefits Of Annual & Biennial Flowers

  • With biennial flowers garden owners can create a continuous display of blooms in their garden by planting fresh seeds every year, so there is always a set of flowers in their first cycle, and a set in bloom during their second
  • Commercial gardeners or landscapers can control bloom displays with annual and biennial flowers
  • The lack of continual growth means gardeners are able to enjoy a wide variety of annual and biennial flowers if they want to grow something different, because the entire plant dies and leaves a space for another one behind
