are plants that require two seasons to complete their life cycles (seed germination to seed production); the first for vegetative growth and the second for flowering and setting seed
Plants completing their life-cycle within two years The first year it produces leaves and stores food while the second year it produces fruit and seeds
A plant that requires two years to complete its life-cycle, germinating and growing in its first year, then producing its flowers and fruit in its second year, after which it usually dies
A plant grown from seed that under normal conditions takes two years to complete its life cycle, developing a leafy tuft or rosette the first season then flowers, seeds and dies the second year
A plant whose life cycle extends over two growing seasons The first year the seed germinates and produces a seedling that usually remains short of the winter The second growing season the seedling rapidly grows, flowers, produces seeds and then dies
a plant having a life cycle that normally takes two seasons from germination to death to complete; flowering biennials usually bloom and fruit in the second season having a life cycle lasting two seasons; "a biennial life cycle"; "parsnips and carrots are biennial plants often grown as annuals"
A biennial event happens or is done once every two years. the biennial Commonwealth conference. Any plant that completes its life cycle in two growing seasons. During the first growing season biennials produce roots, stems, and leaves; during the second they produce flowers, fruits, and seeds, and then die. Sugar beets and carrots are examples of biennials. See also annual, perennial
Somwhat of a misnomer seeming to mean a plant that completes a life cycle in two years It actually is often applied to plants that generally take more than one season or yearly cycle to complete a life cycle Basically the term applies to plants that die at the end of a life cycle (they die after they produce seeds) but don't complete that cycle in one season Many plants take an indeterminate number of years to complete the growth necessary to reproduce See; perennial, annual, monocarpic
Whereas annuals complete their life cycle in a single year, biennials take two, flowering and setting seed on the second Biennials occasionally complete their growth cycle in a single year
A plant which completes its life cycle in two years Usually has leaves and stores food in underground parts the first year and then blooms, produces seeds and dies the second year
