Spireas are small to medium sized deciduous shrubs that produce cascades of flowers in spring and summer.
Among the easiest flowering shrubs to grow, spireas are often used in foundation plantings, as hedges, and in perennial gardens. Most spireas bloom in late spring to midsummer. Flower colors include pink, red, yellow, and white, depending on the variety. Some types have colorful fall foliage. Size depends on the species and variety, and can range from 2 to 10 feet tall and wide.
