One way to organize the thousands of types of flowers is by their growth habits. Annuals, perennials, and biennials are the three main types of flowers, each with its own subcategories, as well. Annual flowers like sunflowers germinate, grow, flower, produce seed, and finally die all in a single year. Other kinds of flowers like perennials live and flower for multiple years, including blooms like the coneflower. Biennials fit somewhere in between annuals and perennials; they flower and die in their second year. Whether you’re looking to order birthday flowers in the summer or send a bouquet of sympathies in the winter, this list can help you make your selections based on the different category of flowers. Also, browse through our blog and you can learn even more about various kinds of flowers, including cherry blossom facts and guides to native Mexican flowers.
While these plants differ in how they grow, they all produce gorgeous flowers at some point in their lives. To help you understand and explore the types of flowers a bit more, we’ve broken down each of the three categories. Dive into the lists and you’ll find a new flower to add to your garden or the best one to choose the next time you order flower arrangements. Just make sure you take all the proper precautions for pets and children in mind, so you don’t end up choosing to plant potentially poisonous flowers.
Annual Flowers
Annual flowers don’t waste any time spreading themselves throughout the world. These kinds of flower germinate, bloom, and set seeds all in one year. While this means you’ll have plenty of seeds to plant in the future, it also means you only get to enjoy an annual plant for one year.
Just because a flower is annual doesn’t mean it can’t tolerate cold. While tender annuals can’t handle frost, hardy annuals can withstand some cold and light frost. If you are looking to plant winter flowers, make sure you find the right blooms.

These flowers generally live in prairies or meadows where they release seeds to keep flowers blooming each year.

Unlike annuals, perennial flowers live for more than one year. They may bloom and set seed their first year, or they may even take multiple years to flower.

While perennials may appear to die during cold periods, they should regrow in the spring, though it’s important to note that not all perennials can survive cold temperatures. Tropical perennial plants, sometimes known as tender perennials, can survive years in warm areas but die during cold winters. Therefore, you’ll need to replant them each year in cold regions.
