They key to any all season flower garden is choosing plants that bloom at different points during the year. Because plants bloom differently in different regions, knowing how and when plants bloom in your region is essential to making a good all season flower garden plan.
Most spring bloomers are bulbs, but a few grow from seed. Crocus is the earliest spring bloomer in most flower gardens, where the small flowers often poke through the last winter snows. Other bulbs such as daffodils, irises and tulips bloom once spring truly sets in.
The plants in the daisy family make excellent choices for the summer stage of the flower garden. Black-eyed Susans, zinnias and Gerbera daisies bloom throughout the hottest months. Rose bushes add verticality and fragrance to any summer flower garden.
Asters, which are also in the daisy family, bloom from the end of summer through the beginning of fall. Chrysanthemums are an excellent choice for fall gardens, as these plants are very easy to care for and frequently return in successive years. Hardy flowers like pansies bloom through late fall and even into winter.
In temperate regions, some plants flower throughout the winter. Most pansies planted in the fall continue to flower in the winter, as these plants can tolerate all but the bitterest temperatures. Hellebore, also known as the Christmas rose, is also a winter bloomer.
