Flowering annuals are plants that

• A. re-bloom year after year
• B. usually cannot be grown from seed
• C. grow, flower, and produce seed in a single season
• D. should not be combined with spring-blooming bulbs

Answer: (C)

Flowering annuals complete their life cycle in one growing season: they germinate, grow, flower, produce seeds, and then die. That’s why the defining trait is that they grow, bloom, and set seed within a single season. Because of this life cycle, gardeners typically plant new generations each year for continuing color. In contrast, perennials survive to bloom again in later years, and some plants take two years to finish their life cycle, so their behavior isn’t like annuals. Annuals can usually be grown from seed, so it isn’t accurate to say they cannot be grown from seed. And planting annuals with spring-blooming bulbs is a common, flexible combination rather than a defining restriction.
