AnnualsAnnuals are plants that complete their entire life cycle – germinating, growing shoots and leaves, flowering, setting seeds and dying – within a period of less than a year. (Biennials, in contrast, typically take two seasons to complete their lifecycle.)
Here in the Northwest, we plant annuals in early spring once the frosts subside. They bloom in late spring or early summer, and continue to provide gorgeous color until the fall frosts set in.
