Annual flowers for Central Region
If you live in the Ohio Valley or Central region, annuals can be used to bring color to flowerbeds as border plants, in planters, and hanging baskets. Central region and Ohio Valley annuals can be chosen for their flower color, plant height, and growth requirements. Since these flowers are only grown for one season, winter hardiness is not a primary consideration when selecting species. Many times, these plants are started indoors much the same as garden vegetables. Annual flowers can be transplanted outside once the danger of frost has passed. Additionally, many perennial flowers are grown as annuals in the Central region and Ohio Valley. These flowers survive winters in tropical or subtropical climates but may not be winter hardy in the colder climate of northern states.
Ohio Valley and Central Region Annuals
When choosing annual flowers, match the sun and soil requirements of the plants to the specific location in the flowerbed. Try planting taller annuals in the back and shorter types along walkways and borders. Using a variety of plant shapes and foliage patterns adds to the visual appeal. To create a visually stunning garden, try choosing species by their flower color. You can pick variations of a single color palette such as the lavender of alyssum, the deeper purple of petunias, or the various hues of cleome. Combine colors to create a patriotic display using red salvia, white petunias, and blue ageratum. Or contrast colors with shapes such as the spikes of blue salvia with the round flowers of orange marigolds.
