Flowering shrubs are one of the easiest ways to liven up your landscape. And shrubs that bloom all summer—with zero help from you!—provide structure to planting beds, attract pollinators and add tons of curb appeal. You’ll plant them once and enjoy them for years—how awesome is that? Better yet, some summer-blooming shrubs start flowering in late spring and bloom all the way to a hard frost. (Other reblooming types have their biggest show early in the season, then bloom off and on throughout the season or again with another big flush in early fall.)

When shopping, make sure the shrub is suited to your USDA Hardiness Zone (find yours here). Then plant it in the proper exposure, meaning if it says full sun, you’ll need a spot that gets at least 6 hours or more of direct sunlight. Blooming shrubs need sun in order to flower, so don’t place them in deep shade or you’ll be disappointed. Also, make sure to keep your plant watered as it’s getting established. Flowering takes lots of energy, so you don’t want to stress your new plant out if you’re having a dry spell.

1. Butterfly Bush

  • Why We Love It: great scent, spiky flowers, attracts pollinators
  • What It Needs: full sun

One of the easiest shrubs to grow, butterfly bush is a favorite of pollinators, since they have a delightful honey scent. They come in a variety of sizes, ranging from around 18 inches tall to five feet tall, in various shades of pink, white and purple. Breeders also have developed new varieties which are not invasive, so they won’t take over your garden.


2. Shrub Rose

  • Why We Love It: elegant garden flower, low maintenance, great scent
  • What It Needs: full sun

Modern shrub roses start blooming in late spring and keep going until a hard frost. They’re not fussy and have been bred to be more vigorous and disease resistant. Many new shrub roses also boast beautiful fragrances, which adds one more layer of enjoyment to your garden.

3. Smooth Hydrangea

  • Why We Love It: native plant
  • What It Needs: morning sun, afternoon shade

This type of hydrangea, native to North America, has huge blooms that last for months and months. On many varieties, the papery flowers persist through fall. Newer types have been bred to ensure stems stay upright after summer storms. Look for dwarf types, too, that fit better in compact gardens.

4. Potentilla

  • Why We Love It: extremely hardy shrub, drought-resistant
  • What It Needs: full sun

Potentilla is tough-as-nails, so it’s a great plant for dry, hot locations. Its small blooms in white, pink or yellow start in late spring and keep going and going until a freeze. You almost can’t kill this shrub.

5. Reblooming Spirea

  • Why We Love It: neon-bright flowers
  • What It Needs: full sun

Spireas have been popular forever because they’re super-tough shrubs. But new reblooming types boast the allure of gorgeous clusters of flowers in late spring, with reblooms throughout the summer.

6. Panicle Hydrangea

  • Why We Love It: easy to grow, handles cold well
  • What It Needs: full sun with afternoon shade in hot climates

Big, cone-shaped blooms appear in mid-summer and stay beautiful until a hard frost. The blooms start white or green, then take on lovely pink hues. They’re the easiest type of hydrangea to bloom and are very cold hardy. They also make great cut flowers for drying.

7. Crapemyrtle

  • Why We Love It: gorgeous flowers that can take the heat
  • What It Needs: full sun

Crapemyrtle shrubs have vividly colored flowers in white, hot pink or red. They’re tolerant of heat, and depending on the variety, the blooms may last all summer. New types have been bred to be more compact, so they’ll fit in small gardens.

8. Reblooming Azalea

  • Why We Love It: repeat blooms later in the season
  • What It Needs: dappled shade

Azaleas are gorgeous shrubs when they burst into bloom in mid to late spring, depending on where you live. But then the show is over for the year. However, breeders have developed new types that rebloom later in mid to late summer through frost, giving you twice the joy from one plant. They’re especially lovely in mass plantings.

9. Chaste Tree

  • Why We Love It: blue blooms, an uncommon color in garden flowers; deer resistant
  • What It Needs: full sun

Chaste tree, also known as vitex, is a stunning shrub that attracts oodles of pollinators with its lovely blue blooms. It doesn’t mind hot weather and deer don’t tend to mess with it. Look for the dwarf variety, which maxes out at 6 feet tall and wide, to keep it manageable in small spaces.

10. Summersweet

  • Why We Love It: shade-tolerant, sweetly scented
  • What It Needs: part shade, part sun

Summersweet is a lesser-known shrub, but it’s absolutely beautiful and will tolerate shade, unlike many other flowering shrubs. The blooms last for weeks and weeks in midsummer and boast a delicious cherry-vanilla scent. It’s deer resistant and gets pretty yellow fall color.

11. Oleander

  • Why We Love It: bright pink flowers year-round in warm climates
  • What It Needs: full sun

Oleander has bright pink, red or white flowers and evergreen foliage, so it’s a great choice for year-round color in warm climates. In northern climates, it can be grown as a patio container.

12. Beautyberry

  • Why We Love It: three seasons of color
  • What It Needs: Full sun

Technically, beautyberry doesn’t bloom all summer. But what it does do is show off from spring to frost! In spring, you’ll get gorgeous purple foliage, followed by pretty white flowers in summer, transitioning to hundreds of stunning violet-colored berries in fall. Look for smaller dwarf types that have a more upright form.
