A species with a life cycle which takes approximately 12 months or rather less to complete, whose life cycle is therefore directly related to the annual cycle of weather, and whose generations are therefore discrete.

A plant that completes its life cycle in 1 year, i.e., germinates from seed, produces seed, and dies in the same season. Examples include pigweed, ragweed, mustard, foxtail, and crabgrass.
