Choose a color theme for your flower garden. Choose flower colors that provide contrast, such as pairing bright orange with deep purples, for a dramatic display. Alternatively, grow many flowers of the same color but in varying hues.
Select several perennials that bloom at varying times. Perennials return every year, increasing in size and vigor, and add color at predictable times. Try Shasta daisies, coneflowers and garden phlox for a bright display of color from early summer to fall.
Place tall flowers, such as hollyhocks, foxglove and delphinium, in the background of beds that will be viewed from one side, or in the center of round or oval beds that will be viewed from multiple viewpoints. Add medium-height flowers, such as daisies and coneflowers, next and finish off with mounds of low-growing flowers to create a visually appealing flower garden.
Tuck fall bulbs, such as daffodils, crocus and tulips, between the perennials for a brilliant display of color in early spring before other perennials bloom. These bulbs bloom as soon as the soil thaws, often emerging through the last remnants of snow.
Add brightly colored annuals as soon as the weather warms and the danger of frost has passed in your area. Many bloom from late spring well into the fall. Try petunias, impatiens, begonias and marigolds for color that lasts all season.
Tie the flowerbed together with wind chimes, hummingbird feeders or bird baths to add movement and interest. A small fountain, garden art or decorative stones bring the bed to life and create a focal point.
