Looking for that amazing “pop” of color in your garden or landscape? A plant that makes a statement and really stands out against your backdrop?

Enter… flowering perennial shrubs (or bushes). Perennial shrubs add balance and color to your landscape.

I love flowering shrubs because they can really catch the attention of passerbys. If you’re following my garden pyramid for planting success, you have already chosen your ornamental tree(s) and evergreen shrubs.

Flowering shrubs make the perfect choice for right in front of your evergreen backbone planting. So, place your perennial shrubs in front of a row of evergreens to really make them POP. 

These flowering bushes can add lots of long-lasting color and personality and are large enough to make a big statement. In fact, a lot of the perennial shrubs I’ll mention are long-blooming; for weeks and even months on end. 

And… when they are done blooming, your sturdy evergreen foundation will keep your garden from looking bare and messy. Once you choose the perennial shrubs that are right for your garden, you’ll see your landscape really start take shape.

Quick Tip: My landscape layering post  will show you how to create a beautiful, four-season landscape, even if you’re a beginner gardener!

Long Blooming & Easy-Care Perennial Shrubs

Here are some of my favorite perennial shrubs that you can plant in your own garden. I really love these options because not only do they bloom for a long time but they’re also low maintenance, making them great for beginners.

The only things you’ll need to do is keep them watered and fertilized. After planting these shrubs you should supplement their water supply until the roots get established.  Beyond that, they should be able to handle the weather if you get about an inch of rain each week.

Many people find flowering shrubs to be difficult to grow. The biggest issue that I see, is that most people do not fertilize flowering shrubs enough — or at all. Any plant, shrub or tree in your garden that is a prolific bloomer needs to be fertilized.

It takes a lot of energy for her to look so beautiful for you every day! So… you should pick up some plant fertilizer and follow the feeding instructions provided. My favorite is Espoma Rose-Tone Rose and flower food if you are looking for a specific recommendation!

Ok – onto my recommendations for the best perennial flowering shrubs for you to try in your own garden!

The Best Spring Flowering Shrubs

Azalea ‘Hot Shot Girard’

A beautiful fiery flowering shrub, ‘Hot Shot Girard’ Azalea blooms in mid-spring, but its semi-evergreen nature and small size makes it a workhorse in your mixed border all year long.

A great partial sun option for a mixed border, ‘Hot Shot Girard‘ azalea is a hardy, ornamental evergreen shrub with brilliant flowers. This azalea catches fire in mid-spring with orange-red 3″ ruffled blooms. It also attracts butterflies.

Elderberry ‘Black Lace’ (Sambucus nigra ‘Eva’) is similar to Black Beauty, but with a bit darker purple foliage with a finer, fern-like texture similar to the Japanese Maple.

Zones: 4-7 | 8-12′ H x 5-6′ W | Full to Part Sun
Blooms in late spring, berries in the fall.
Native to Europe, southwestern Asia and northern Africa

Elderberry ‘Black Beauty’ begins its show with clusters of lovely, lemon-scented pink blooms in spring. The deep, burgundy, fern-like foliage looks gorgeous when it’s not in bloom. It also attracts birds (and people) with tasty summer berries. 

-Amy Fedele, Pretty Purple Door

The European Elderberry ‘Black Beauty’ (Sambuscus nigra ‘Gerda’) has exotic, fern-like deep purple foliage with purple young stems. In spring, pink blooms with a lemony scent envelop this unique shrub, attracting butterflies. It also bears yummy edible fruit (elderberries) in the summer that both people and birds love. The cultivar ‘Black Lace’ is similar to ‘Black Beauty’, but the foliage is a shade darker with a finer, fern-like texture similar to a Japanese Maple.

Note: In order to produce berries, plant a compatible pollinator nearby (Black Beauty, Black Lace, Instant Karma, or Laced Up elderberry will cross-pollinate).

American Black Elderberry (Native)

If you have the space for it, take a look at the American black elderberry (Sambucus canadensis), native to a large area of North America. It’s a loose, graceful, deciduous shrub with green foliage and white blooms. It grows 8-12′ high and wide in Zones 4-9.

Pinkie is adorned with pink flowers in spring, has dark berries to attract birds in the summer and will even keep its foliage throughout the winter.

-Amy Fedele, PRetty Purple Door

Indian Hawthorne is a double bang-for-your-buck plant because it’s an evergreen shrub but is just as beautiful as the other perennial shrubs in this list. ‘Pinkie’ (Rhaphiolepis indica ‘Pinkie’) is a good variety to check out in Zones 7-9 for its compact size (2-5’H x 3-4’W). 

The Indian Hawthorne is a no-fuss small and slow-growing shrub. It bursts with pink or white clusters of flowers in spring on rich, glossy evergreen foliage. The flowers give way to dark, blue berries that attract birds and other wildlife the rest of the year.

A must have flowering shrub for any garden is the “knockout” or “double knockout” rose bush — these can bloom up to 9 months of the year and are very easy to care for.

Knockout or double knockout roses are easy to grow, don’t require special care and bloom up to 9 months of the year — literally from spring until the end of fall when it starts to frost.

Knockout roses come in a couple different variations of color. Most are in the hot pink (Rosa PINK KNOCK OUT ‘Radcon’) to blush pink (Rosa x ‘Radgor’), or yellow family (Rosa SUNNY KNOCK OUT ‘RADsunny’) .

I love ‘Little Quickfire’ for many reasons. It has red stems with white blooms that slowly fade to rosy pink. It tolerates full sun. And it blooms about a month earlier than other hydrangeas!

-AMY FEDELE, PRETTY PURPLE DOOR

If you’re looking for a flowering perennial shrub that can tolerate some shade, Hydrangea ‘Little Quickfire’ is a great option. Native to China and Japan, white blooms appear in early summer – about 1 month sooner than other hydrangeas. As the blooms age, they fade to a pink color (like in the photo). Little Quickfire is a more petite version of Quickfire, which gets 6-8′ tall and wide.

Virginia Rose

Also known as common wild rose or prairie rose, the Virginia Rose blooms with fragrant, 1-3″ pink flowers in early summer and then blooms sporadically into late summer (June-August). It is not deer resistant.

Virginia rose can be used in a mixed border or pruned into a low, informal hedge. Due to its colonizing habit, is often used to stabilize sunny slopes, at the edge of water or near low-lying, seasonally damp areas.

The pink blooming spirea pictured is called Superstar (Spiraea x bumalda ‘Denistar’). This is a compact (2-3’H x 1-4’W) variety with blooms of apple-pink blossoms that cover the plant all summer long. In addition to the blooms it also has beautiful fall foliage.

So uniquely beautiful, you will never regret planting a smoke bush. With dwarf varieties like Velveteeny widely available, even gardeners with small spaces can grow this show-stopper.

-Amy Fedele, Pretty Purple Door

At just 3-4′ tall, smoke bush ‘Velveteeny’ offers the same silky smooth, deep burgundy foliage with large feathery dove gray/pink plumes in summer. In the fall, its unique purple foliage transforms to bright red, adding an additional season of interest. Velveteeny has similar qualities as her big brother ‘Royal Purple‘ (12-15’H x 10-12’W), but in a petite, dwarf form perfect for small home landscapes.

Beyond Midnight Bluebeard

Bluebeard ‘Beyond Midnight’ (Caryopteris x clandonensis)

Full Sun, 2-3′ W x 2-3′ H, Zones 5-9
Blooms in late summer
Native to east Asia

Bluebeards add big interest in a small package, bursting alive with “true blue” blooms on long stems in late summer. These aren’t used in home landscapes as much as they should be!

Amy Fedele, Pretty Purple door

Beyond Midnight Bluebeard (Caryopteris x clandonensis) is a lovely vibrant green shrub, with a naturally rounded shape. Beyond Midnight adapts to a variety of soils and is drought resistant once established. Even though wildlife love it, destructive deer will pass it by. Its true value is seen as the season progresses. In late summer, long stems shoot up above the glossy, dark-green foliage COVERED in deep-blue flowers. There are so many blue blossoms shooting from these long wands that it has the effect of turning the shrub into a  big blue ball in your landscape. So cool!

Shrubs for Fall Color

Hydrangea ‘Invincibelle Limetta’ (Native)

Zones 3-8| 3-4′ H x 3-4’ W | Full-Part Sun
Blooms early summer through fall
Native to North America

‘Invincibelle Limetta’ is a smooth, U.S. native hydrangea. This dwarf shrub with beautiful lime green blooms easily earns its place in any small garden.

-AMY FEDELE, PRETTY PURPLE DOOR

You’ll have blooms, blooms and more blooms for months from early summer through fall. Invincibelle Limetta® Hydrangea (Hydrangea arborescens) is a dwarf version of the Annabelle Hydrangea. It’s a smooth hydrangea native to North America. Pretty pale green (almost white) reblooming flowers emerge in early summer, brightening to lime green and aging to jade green as the weather cools.

What’s wonderful about Limetta is it’s dwarf size and strong stems that won’t flop over, even under the weight of large blooms. This is one of the most winter hardy of the hydrangeas and it also thrives in urban conditions. Bloom occurs on current season’s growth, so prune as needed in late winter to early spring.

Rose of Sharon ‘Blue Chiffon’

Hibiscus syriacus

Rose of Sharon is a abundant bloomer that works well as a corner foundation shrub because of its height. It will also add interest in late summer & fall after many flowering shrubs have already faded.

Zones 5-9| 8-12’ H x 5-6’ W | Full Sun
Blooms mid-summer to fall
Native to Eastern Asia

Rose of Sharon (Hibiscus syriacus) is sure to provide some much-needed color to your mid-summer and fall garden. ‘Blue Chiffon‘ boasts blue flowers with lacy centers of light lavender-blue petals give it a semi-double appearance. The flower centers are accented with wine-red hues that streak out from the veins of the petals.

Also take a look at ‘Blushing Bride‘. This variety has pale pink flowers with lacy centers giving its blooms a semi-double appearance.

Wrapping Up

For a 4-season layered landscape, plant your perennial shrubs IN FRONT OF your evergreen shrubs. Evergreen shrubs are the perfect backdrop for these blooming pops of color.

When searching for the perfect perennial shrub, look for ones that have interest in multiple seasons. Maybe it blooms in spring, but has beautiful fall foliage or produces summer berries. Maybe it has a uniquely-colored foliage all year and also has scented blooms. This is especially important in small gardens, where space is extremely limited.

And, be sure to keep reading this guide as we’ll be talking about using perennial plants and flowers in the landscape next!

In my perennial garden plan, I’ll go over landscape layering and give you some suggestions for each of the 5 layers:
Layer 1: Ornamental Trees
Layer 2: Evergreen Shrubs
Layer 3: Perennial Deciduous Shrubs
Layer 4: Perennial plants and flowers
Layer 5: Groundcovers, Vines and Grasses
