What is an annual plant?

Answer 1

Annual plants are those that complete their lifecycle within one growing season; normally a period of between 3 and 5 months.

This means they germinate from seed, grow, flower, produce seed of their own and then die.

Annual plants are also called "seasonal plants"

Examples are:

Pansy

Petunia

Marigold

Violet

Begionia (fiberous rooted ones)

Celosia

Zinnia
They complete their life cycle in a year or less.

Answer 2

An annual is a publication which is published serially once a year, or a plant which has a life span of one growing season.
