Flower

A flower is the reproductive structure of a flowering plant (an angiosperm), usually the part that produces pollen and ovules and later develops into seeds and fruit.

Updated July 27, 20261 min readCited sources

A flower is the reproductive structure of a flowering plant (an angiosperm). It typically has four main parts: sepals, petals, stamens, and a pistil, and functions in pollination and seed formation.

What it is

Flowers are the reproductive organs of angiosperms. A typical flower is arranged in whorls: the outermost sepals protect the bud, petals attract pollinators, stamens produce pollen, and the pistil contains the ovules. This structure enables pollination, fertilisation, and the development of seeds and fruit.

Key types

Flowers are grouped by growth habit — annuals, perennials, and biennials — and by plant form, such as shrubs and trees. Common examples include roses, tulips, daisies, lilies, sunflowers, chrysanthemums, orchids, and zinnias. Large families include Orchidaceae, Asteraceae, and Rosaceae.

Symbolism and uses

Flowers carry cultural meanings: tulips symbolise love, sunflowers adoration, daffodils new beginnings, lilies purity, and poppies remembrance. Many are grown in gardens, as cut flowers, or in floral arrangements for gifts and celebrations. Canadian gardeners and florists commonly use these species.

In short
