Perennials

Perennials

Perennials, or plants and flowers that come back year after year, are found in virtually every yard. Perennial flowers work in multiple situations: in whole garden beds, in combination with annuals and bulbs, as accent to shrubs and trees, and in containers and windowboxes. In addition, perennials often increase in size each year, which means they can often be divided and added to other spots in the landscape. The Better Homes and Gardens Plant Encyclopedia contains a wealth of information to help you tend to your existing perennials as well as add new and interesting plants to your landscape. The searchable tool enables you to search by perennial common or scientific name, plant characteristics, growing season, and common uses. You'll also discover what perennial plants work well in sun or shade, USDA Hardiness Zones, growing requirements, and planting suggestions for perennials.

303 Perennials
African Iris, Dietes iridioides
Light:
Part Sun, Sun
Height:
1 to 3 feet
Zones:
8-11
Type:
Bulb, Perennial

African iris is a great all-purpose plant for home landscapes in Zones 8 and above. Its sturdy, reed-like foliage is evergreen and a wonderful accent plant in the landscape. Count on bright white flowers to decorate the clumps of 2- to 4-foot-tall plants from spring to fall. Call on African iris to add color and texture to tough landscaping areas, such as parking strips, flanking driveways, and dry patches near a home's foundation. It stands up to heat, drought, and neglect.

Agapanthus, Agapanthus
Light:
Part Sun, Sun
Height:
From 1 to 8 feet
Zones:
7-11

These wonderful flowers are blooming machines and essentially the tropical equivalent of the daylily. A landscape staple in warm-winter regions, agapanthus is a low-maintenance perennial that produces colorful globes of blue or white trumpet-shape flowers in summer and fall. Agapanthus' evergreen strappy leaves add texture to beds, borders, and containers, too. With that combination of attributes, what more can you ask for?

Agave, Agave
Light:
Sun
Height:
From 1 to 20 feet or more
Zones:
5-11
Type:
Perennial

The agave species is known for its architectural foliage available in a variety of colors. Some stay small enough for a pot; others send flower spikes that can reach heights of over 30 feet when in bloom. No matter the size, shape, color, or texture, agave adds drama to any garden. Parts of the plant can be made into agave nectar, tequila, and the fiber known as sisal.

Ajuga, Ajuga
Light:
Shade, Sun
Height:
Under 6 inches
Zones:
4-10
Type:
Perennial

In the world of groundcovers, there isn't a whole lot to get excited about. Enter ajuga. With a wide variety of foliage colors usually in the rich deep burgundy realm, and sometimes cream and pink edges, ajuga offers more than just a bland green mat. The foliage is generally crinkled and very glossy as well. However, if you think this is just a foliage plant, you would get quite the surprise come spring. Once spring eases into summer, ajuga is covered in little spikes of bright blue, purple, pink or white blossoms.

Allium, Allium
Light:
Part Sun, Sun
Height:
From 6 inches to 8 feet
Zones:
4-9
Type:
Perennial

It's hard to believe this stunning flower is a close relative of the onion. Allium holds its stunning bloom high above the foliage, adding whimsy and drama to any planting beds. With hundreds of species available in the onion family, it is quite easy to have blooming alliums every season in the garden.

Alstroemeria, Alstroemeria
Light:
Part Sun, Sun
Height:
1 to 3 feet
Zones:
6-10
Type:
Bulb, Perennial

The cut flower of all cut flowers, alstroemeria is a staple flower in almost all bouquets. With blooms that can last up to two weeks and a color palette almost as wide as the spectrum itself, it is easy to see why. This South American native has made itself into a commodity for the flower markets—and has even worked its way into home gardens.

Anemone, Anemone
Light:
Part Sun, Sun
Height:
1 to 3 feet
Zones:
4-8
Type:
Perennial

Also known as windflower, anemones are grown for their beautiful, nodding blooms on long, wiry stems. The foliage looks similar between varieties, but size and bloom times vary between spring, summer, or fall. Fall-blooming Japanese anemones are particularly noteworthy because they fill the midsummer-to-fall gap in gardens.

Plant anenome in our year-round garden plan.

Angelica, Angelica
Light:
Part Sun, Sun
Height:
From 3 to 20 feet
Zones:
5-9
Type:
Herb, Perennial

Angelica is a tall, hardy biennial herb with dramatic stalks that can be candied and used on cakes or cookies. The first year, the plant produces beautiful frilly green foliage. The second year, angelica sends up flower stalks and then produces seeds. The flowers and foliage make a dramatic back-of-the-border accent in perennial beds. The celery-flavor stems may be eaten raw or candied for use in baking. Use the dried root in tea. Plants might self-sow, but plant new angelica each year to ensure a constant supply. Grow it in full sun or dappled shade in rich, organic soil.

Artemisia, Artemisia
Light:
Sun
Height:
1 to 3 feet
Zones:
3-9
Type:
Perennial

Grown primarily for its silver foliage, artemisia is a wonderful accent plant in many settings. Artemisias come in numerous different foliage shapes, sizes, and heights. A few well-known artemisias are 'Silver Mound' and the herb tarragon. Use these plants to add texture and subtle color to gardens, containers, and borders. Artemesias are also extremely versatile and drought tolerant.

Asparagus Fern, Asparagus
Height:
1 to 3 feet
Zones:
9-11
Type:
Annual, Houseplant, Perennial

Versatile asparagus fern is an attractive herbaceous perennial that is easy to grow, though not actually a fern. Plant asparagus fern in garden beds where it is used as a creeper in warmer climates. It can be invasive, so keep an eye on it. You will more often find asparagus fern growing indoors as a dense, bushy houseplant with lace-like foliage that forms an incredible mound.

Aster , Aster
Light:
Sun
Height:
From 1 to 8 feet
Zones:
3-9
Type:
Perennial

Asters get their name from the Latin word for "star," and their flowers are indeed the superstars of the fall garden. Some types of this native plant can reach up to 6 feet with flowers in white and pinks but also, perhaps most strikingly, in rich purples and showy lavenders.

Not all asters are fall bloomers. Extend the season by growing some of the summer bloomers, as well. Some are naturally compact; tall types that grow more than 2 feet tall benefit from staking or an early-season pinching or cutting back by about one-third in July or so to keep the plant more compact.

Astilbe, Astilbe
Light:
Part Sun, Sun
Height:
From 1 to 8 feet
Zones:
4-8
Type:
Perennial

A garden favorite for moist sites, astilbe can be thought of as a multi-interest perennial. Astible is a knockout plant, thanks to its ornamental, fern-like bronze-and-green foliage and its feathery plumed blossoms that look good both in season and dried for winter interest. Just make sure to keep astilbe moist, or its delicate foliage will scorch in the sun.

Avens, Geum
Light:
Sun
Height:
Under 6 inches to 3 feet
Zones:
3-9
Type:
Perennial

Avens, also called geum, cheer up the landscape with its red, orange, and yellow blossoms for several weeks in spring and early summer. Low-mounding dark green foliage blankets the soil below the tall, airy flowers, providing year-round interest.

Baby's Breath, Gypsophila
Light:
Sun
Height:
From 6 inches to 8 feet
Zones:
4-9
Type:
Perennial

With its loose, billowy panicles of tiny single or double pink or white flowers, baby's breath provides a lightness and airiness to flower gardens. The creeping forms drape beautifully over rock walls. After bloom time, shear the plants to deadhead and for neatness. Plants prefer sweet (alkaline) soils with full sun and excellent drainage.

Balloon Flower, Platycodon
Light:
Part Sun, Sun
Height:
Under 6 inches to 3 feet
Zones:
4-9
Type:
Perennial

The inflated buds of balloon flowers are fun to pop. And they make great cut flowers. Cut them in the bud stage, and sear the base of the stems to prevent the milky sap from seeping out and fouling the water.

Most commonly available in blue-violet, balloon flowers also come in pink and white, as well as shorter forms that are better suited for rock gardens and containers. In fall, the foliage of balloon flower turns clear gold, so don't cut the plant down too early -- enjoy the show! They tolerate light shade, but not wet feet or drought.

Baptisia, Baptisia
Light:
Part Sun, Sun
Height:
From 1 to 8 feet
Zones:
3-8
Type:
Perennial

Commonly known as false indigo, this rugged native prairie plant features tall spires of colorful blooms along with attractive blue-green foliage. Flowers are followed by large clusters of showy seed pods that dry out as they mature and create a rattling noise in the breeze.

Barbara's Buttons, Marshallia caespitosa
Light:
Part Sun, Sun
Height:
Under 6 inches to 3 feet
Zones:
5-8
Type:
Perennial

Add a burst of whimsy to the garden! Slightly wayward stems and loose, rounded flower clusters give Barbara¿s buttons a fun, carefree appearance. It is guaranteed to enliven a staunch border with Dr. Seuss-like spirit. Add this North American native and up-and-coming perennial to beds and borders in full sun or part shade. It grows best in moist, well-drained soil. Blooming in late spring, it is a great partner for spring bulbs. When the tulips and daffodil blooms are fading it bursts onto the scene, carrying the garden into summer.

Barren Strawberry, Waldsteinia fragarioides
Light:
Part Sun, Sun
Height:
6 to 12 inches
Zones:
3-8
Type:
Perennial

Cover open soil around shrubs, perennials, and walkways with barren strawberry. An evergreen groundcover, barren strawberry is a welcome addition to a lackluster sea of mulch. Native to much of North America, barren strawberry spreads by rhizomes. Unlike some spreading groundcovers that spread aggressively, barren strawberry creeps slowly and is easy to remove if needed.  

Its common name references its strawberrylike foliage. Barren strawberry has bright yellow flowers and glossy, evergreen foliage in spring. Its leaves turn shades of bronze in winter. As its name suggests, it does not produce edible fruit.

Barrenwort, Epimedium
Light:
Part Sun, Shade
Height:
From 6 inches to 3 feet
Zones:
4-8
Type:
Perennial

Although barrenwort may look delicate, it’s anything but fragile. Thriving in shade and in humidity levels ranging from arid to moist, barrenwort displays colorful foliage as well as early-spring flowers. This plant makes a wonderful groundcover in shady areas and tolerates root competition beneath trees and shrubs. Depending on the species, barrenwort can be evergreen or semievergreen, which adds winter interest to its list of attributes.

Basket-Of-Gold, Aurinia saxatilis
Light:
Sun
Height:
From 6 inches to 3 feet
Zones:
3-7
Type:
Perennial

Basket-of-gold is one of those plants that loves to grow in the least likely of places—cracks between paving stones, the edges of gravel paths and patios, rocky outcroppings, and between the stacked stones of a retaining wall. Its clusters of blooms create dazzling blankets of color. And after it finishes blooming, the grayish-green foliage makes an attractive mat in the garden or landscape.

Basket-of-gold is easily grown as a perennial in areas with mild summers. It loves a baked spot with excellent drainage but will struggle in hot, humid areas and tends not to do well in the South. If that’s where you live and garden, you may want to grow basket-of-gold as an annual.
