An annual plant is a type of plant that completes its life cycle within one growing season. This means it germinates from seed, grows, flowers, produces seeds, and then dies all in the span of a year. Common examples of annual plants include marigolds, zinnias, and tomatoes. These plants are often favored in gardens because they can provide vibrant blooms and fresh produce quickly. Annuals typically require replanting each year, as they do not survive the winter in colder climates. Their rapid growth and flowering make them popular choices for seasonal displays and vegetable gardens.
