13 Beautiful Blooming Shrubs to Fill Your Garden with Color All Summer
Bluebeard
The airy clusters of beautiful blue blooms gave bluebeard its name. The flowers appear in late summer, just when many other shrubs and perennials are fading. This easy-to-grow shrub will take all but the worst heat and drought. Plus, all kinds of pollinators including hummingbirds love the flowers but deer leave it alone. Bluebeard makes a great cut flower, too.

Butterfly Bush
Think of a butterfly bush like a summer-flowering lilac. The blooms appear in similar colors (purple, lavender, blue, pink, and white) and are deliciously fragrant. Happily, butterfly bushes have a longer bloom season than lilacs: From summer into autumn, especially if you pinch off the old flower clusters as they start to fade. This also will help them not self-seed everywhere and become invasive.
Light: Full sun
Water: Evenly moist, well-drained soil
Size: To 10 feet tall or more
Zones: 5-9

Oleander
An exceptionally easy-care subtropical shrub, oleander offers summertime flowers in shades of pink, red, purple, lilac, yellow, and white.

Take care if you grow it in your garden though, especially if kids or pets are around: Oleander is extremely poisonous if eaten.
