No. Flowering plants (angiosperms) are vascular plants. They have xylem and phloem that move water and nutrients, plus true roots, stems, and leaves, and they reproduce with seeds formed in the ovaries of flowers.
Nonvascular plants are a separate group—mainly mosses, liverworts, and hornworts. They lack true vascular tissue, so they stay low to the ground and usually need moist habitats.
