Flowering Shrubs by Season
Upload your photo here.
With careful planning, you can have shrubs flowering in your yard almost all year long. Blooming shrubs are perfect as foundation plants, for screening, or as focal points in the landscape. Some set fruit after flowering, providing a food source for birds, and can be visually appealing on their own. The flowers on most shrubs, such as weigela, drop cleanly after they're done blooming, while dried blooms of hydrangeas can continue to add beauty through fall and winter.
Start the season with a beautiful display of spring-flowering shrubs.
Azalea (Rhododendron spp.)
Azaleas give you a wide array of choices to landscape with: These flowering shrubs appear in nearly any color, can be evergreen or deciduous, and are available in a wide range of sizes. Most azaleas bloom best with partial sun, plenty of moisture, and rich, well-drained, acidic soil. Zones 4-10, depending on type.
Bridal wreath spiraea (Spiraea prunifolia 'Plena')
When the tiny bunches of white blooms drip profusely from bridal wreath spiraea, it conjures up pleasant images of wedding finery. It typically blooms before or as it leafs out, welcoming the spring season. Bridal wreath spirea does best in full sun and moist, well-drained soil. The easy-growing shrub grows up to 6 feet tall. Zones 5-9

Northerners often get a case of Zone envy when they see camellias' glossy, evergreen leaves and stunning roselike flowers in shades of pink, white, or red.

Ninebark (Physocarpus selections)

There are so many kinds of hydrangeas, you'll want them all. The bigleaf (H. macrophylla) types grow with the big pink, white, or blue mopheads in partial shade. The smooth types (H. arborescens, also generically called 'Annabelle' types after its most famous member) grow vigorously in almost any condition. The cold-hardiest of them all, panicle hydrangeas (H. paniculata) prefer full sun. All produce sets of blooms that dry beautifully on the stem or in a vase for winter enjoyment. Sizes and hardiness vary by type and cultivar.
