The Main Flower Categories

Main flower categories

Understanding the classification of the main flower categories is essential for any gardener or farmer seeking to optimize the planning and maintenance of their garden or flower farm. This insight allows for the selection of appropriate species tailored to your specific climatic zone, along with an understanding of their unique cultivation requirements.

Here’s an overview of the main flower categories and their characteristics, to help you make the right cultivation choices.


Annual plants complete their life cycle lifecycle within a single year—from germination, flowering, and seed production, to eventual death. They’re perfect for those who want to see quick results and incorporate varied colors and textures into their gardens every year. Some gardens can benefit from two successions of annuals in the same season, maximizing blooming.

Hardy Annuals

These annuals can withstand light to moderate cold. This makes them ideal for early spring planting or for autumn sowing, enabling early growth the following year. They offer the possibility of beautifying the garden early in the season.

Bulbous plants, including tubers and corms, form a unique category. They store energy in an underground bulb and flower every year. Spring-flowering bulbs are planted in the autumn and need a cold spell to bloom, whereas autumn-flowering bulbs are planted in the spring. They are essential for continuous flowering from early spring to late autumn.


Perennials come back every year, surviving winters and resuming growth in spring. Their ability to bloom for several years makes them an economical, long-lasting choice for any garden. They require less replacement and offer permanent structure to the landscape.

Tender Perennials

These perennials can’t take the cold and are often treated as annuals in cold climates. They are perfect for adding diversity to the garden, but may require annual protection or replacement in some areas.


Biennial plants offer a unique planning opportunity with a life cycle spanning two years. The first year is devoted to vegetative growth. Flowering occurs in the second year, after which they die. They require long-term planning, but can provide spectacular, abundant flowering.

Each plant category has its own charm and specific needs, making your garden or flower farm varied and interesting all year round. The key lies in carefully selecting the right species for your climate and gardening goals.
