Distinguish between perennial, annual and biennial plants.?

Answer 1

Perrenial - plant a young one this year - you get flowers fors for several years to come. It last "forever"

Annual - plant seed this year - you get flowers and seeds this year. don't expect the same one to come up next year. you'll probably lots of it's seedlings though.

Biennial - plant this year - it spends this year growing bigger, flowers next year and don't expect it to flower after that.

Answer 2

Perennials are considered to be ornamental plants that do not die after one season of growth. This does not mean they live forever. In fact many perennials are considered to be short-lived, lasting only 2-3 years. Rose campion is a short lived perennial, but because it self-seeds so readily, it appears to live much longer.
Not all plants with the ability to be perennial are hardy in all areas. This is why planting zones are so important. Knowing what zone you garden in will allow you to determine what plants will survive in your area.

The term perennial is generally reserved for plants with showy flowers, excluding ornamental grasses and other plants mainly grown for their foliage. The term herbaceous perennial further narrows the group to plants with soft, green stems that die back to the ground in colder climates. Trees, shrubs and other woody stemmed plants are excluded.

Examples: Many of the perennial plants I admire are not hardy in my Zone 4 garden


A biennial plant is a flowering plant that takes between twelve and twenty-four months to complete its lifecycle. In the first year the plant grows leaves, stems, and roots (vegetative structures); then it enters a period of dormancy over the colder months. Usually, the stem remains very short and the leaves are low to the ground, forming a rosette. Many biennials require a cold treatment, or vernalization, before they will flower. The next spring/summer the stem of the biennial plant elongates greatly, or bolts. The plant then flowers, producing fruits and seeds before it finally dies. There are far fewer biennials than either perennials or annuals.

Answer 3

Perennial plants come back year after year. Annuals typically last only one growing season, though they can last longer if you live in a mild climate. Biennial plants complete their life cycle in two years.

Answer 4

Perenials grow year after year, plant them once and you will have them for a long time (most bulbs are perennials). Annuals only grow one year (season) and then they die. (most prolific flowering plants are annuals, Pansies ect...) Bienniels will come back depending on the region, and only a couple of years.

Answer 5

annual only bloom once (however some may come back up to 3 years each bloom season.

bi-annual last roughly 2-3 years

perrennials are just what the word states per annual or per year.
these come back each season for years.
