    Bluebeard Shrub

    This shrub is a treat in late summer when it bears its airy clusters of beautiful blue blooms. It's extra-easy to grow, too, laughing off all but the worst heat and drought. As an added bonus, birds and butterflies love it. Bluebeard shrub makes a great cut flower, too.

    Name: Caryopteris varieties

    Growing Conditions: Full sun and well-drained soil

    Size: To 4 feet tall

    Zones: 5-9

    Butterfly Bush

    Butterfly bush is like a summer-flowering lilac. The blooms appear in similar colors -- purple, lavender, blue, pink, and white -- and are deliciously fragrant. Happily, butterfly bushes offer a longer bloom season than lilacs: from summer into autumn, especially if you pinch off the old flower clusters as they start to fade.

    Name: Buddleia davidii

    Growing Conditions: Full sun and well-drained soil

    Size: To 10 feet tall or more

    Zones: 5-9

    Carolina Allspice

    This underused gem offers beautiful deep red flowers in summer. These flowers have a powerful, spicy fragrance you can enjoy throughout the yard. It's also a tough, low-care plant native to areas of North America.

    Name: Calycanthus floridus

    Growing Conditions: Full sun or partial shade and well-drained soil

    Size: To 8 feet tall

    Zones: 5-9

  • White Hydrangea grandiflora 	4 of 16

    Hydrangea paniculata

    Hydrangea paniculata is the easiest hydrangea to grow. In late summer and autumn, this rugged shrub produces fluffy clusters of white flowers that fade to shades of pink and green. Many cultivars, such as 'Tardiva', can be successfully trained into a standard, or miniature tree form -- perfect for a large container or just about any landscape spot.

    Name: Hydrangea paniculata

    Growing Conditions: Full sun or part shade and well-drained soil

    Size: To 10 feet tall and wide

    Zones: 4-8

    Watch this quick video to learn more about beautiful hydrangeas.

  • Nerium, Nerium, Oleander, Shrub, 6 of 16


    An exceptionally easy-care subtropical shrub, oleander offers summertime flowers in shades of pink, red, purple, lilac, yellow, and white. In fact, it's so foolproof that in many areas it's grown along the sides of highways in warm-weather areas. Note, though: Oleander is extremely poisonous.

    Name: Nerium oleander

    Size: To 10 feet tall, depending on species

    Growing Conditions: Full sun and well-drained soil

    Zones: 10-11

    Potentilla is one of the most common, and easiest shrubs to grow. It starts blooming in late spring and continues through autumn, bearing cheery yellow, orange, red, or white flowers that look like single roses (which attract butterflies). It has attractively divided foliage.

    Name: Potentilla fruticosa

    Size: To 3 feet tall

    Growing Conditions: Full sun and well-drained soil

    Zones: 3-7

    Reblooming Hydrangea

    While most bigleaf hydrangeas flower on branches from the last year (making them susceptible to injury from spring frosts or especially cold winter temperatures), reblooming varieties such as 'Endless Summer' produce flowers on fresh growth. This ensures lots of blooms throughout the summer.

    Name: Hydrangea macrophylla varieties

    Growing conditions: Part shade and moist, but well-drained soil

    Size: To 5 feet tall

    Zones: 5-9

    Rock Rose

    Rock roses are easy to grow because they tolerate drought so well. They're beautiful, too, producing colorful roselike flowers throughout the summer. And they bloom in a wide range of colors, from pink to purple, lavender, and white.

    Name: Cistus varieties

    Growing Conditions: Full sun and well-drained soil

    Size: To 5 feet tall

    Zones: 8-10

    Rose of Sharon

    You can rely on rose of Sharon to provide lots of color during the hottest months. From midsummer to early autumn, the shrub erupts in tropical-looking blooms in shades of pink, lavender-blue, and white. Tip: When shopping for rose of Sharon, look for sterile varieties, such as 'Minerva', that won't fill your garden with a ton of weedy seedlings.

    Name: Hibiscus syriacus

    Growing Conditions: Full sun and well-drained soil

    Size: To 10 feet tall and wide

    Zones: 5-9

    Shrub Rose

    Not all roses are finicky, high-maintenance plants. Modern shrub roses offer beautiful blooms all summer and autumn on disease-resistant, easy-growing plants. Flower color differs by variety, but you'll most commonly see shrub roses in shades of pink, red, white, and yellow. Tip: Even modern shrub roses have thorns, so plant them away from sidewalks and pathways.

    Name: Rose varieties

    Growing Conditions: Full sun and well-drained soil

    Size: To 6 feet tall and wide, depending on type

    Zones: 3-9, depending on type

    Smoke Bush

    Smoke bush creates a dramatic shot of color in the landscape, but not because of its pink plumes in summer. It's the foliage that's really spectacular: Most common types have dark purple leaves that erupt into colorful shades of yellow, orange, and red in fall.

    Name: Cotinus coggygria

    Growing Conditions: Full sun and well-drained soil

    Size: To 12 feet tall

    Zones: 5-8

  • Spirea (Spiraea japonica 'Frobelii') 13 of 16


    There's a good reason spirea is a common sight in city plantings, at restaurants and even gas stations: It's a no-brainer to grow. And spirea is beautiful; in midsummer, it produces clusters of raspberry-rose flowers. Many varieties, such as 'Goldmound', also offer attractive golden or lime-green foliage.

    Name: Spiraea japonica

    Growing Conditions: Full sun and well-drained soil

    Size: To 4 feet tall

    Zones: 4-9

    We like summersweet because it blooms in shady spots. We also love that its pink or white flowers have a wonderful fragrance. Add its golden fall leaf color and you have an ideal shrub. Note: Look for cultivars, such as 'Ruby Spice', that offer an extra-long bloom season.

    Name: Clethra alnifolia

    Growing Conditions: Part to full shade and moist soil

    Size: To 5 feet tall

    Zones: 3-9
