What type of life cycle does cutleaf evening primrose have?

• A. Annual
• B. Biennial
• C. Perennial
• D. Aseasonal

Answer: (B)

The plant follows a two-year life pattern: it spends the first year growing vegetatively (usually forming a rosette of leaves and storing energy), then in the second year it sends up a flowering stalk, produces seeds, and dies. This two-year cycle is what defines a biennial.

Annuals complete their life cycle in one growing season, so they flower and die within a year. Perennials live for multiple years and can flower in multiple seasons. Aseasonal isn’t a standard life-cycle category for plants. Because cutleaf evening primrose typically grows vegetatively the first year and flowers in the second before dying, the best description is biennial.
