Spireas are small to medium sized deciduous shrubs that produce cascades of flowers in spring and summer. They are easy to care for and low maintenance. 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 colours include pink, red, yellow, and white, depending on the variety.
- Some types have colourful autumn foliage.
- Size depends on the species and variety, and can range from 2 to 10 feet tall and wide – the classic bridal wreath spirea, grows up to 10 feet tall and 20 feet wide, so give it plenty of room. Masses of small, white flower clusters cover the plant in the spring.
- Trim a spirea plant to increase the number of blossoms in the spring.
To prune spirea, wait until the dormant season, which is in the middle of winter, trim back one-third of the overall plant size, and remove any dead or stray branches.
