Flowering plants are a type of vascular plant that produces flowers in order to reproduce. Flowering plants produce seeds within a fruit. The scientific name for flowering plants is angiosperms. Flowering plants follow a specific life cycle.
The term  perennial  refers to herbaceous (âgreenâ) plants since woody plants, such as trees, are perennial by definition. Unlike annuals, perennials tend to bloom for just a short time â one to three weeks â each year. Examples of popular perennial flowers include tulips, asters, black-eyed susans and lilies.nnual plants are plants with a life cycle that lasts only one year.
