Flower beds make wonderful additions to an outdoor space, providing vibrant pops of color and floral arrangements that can give off a year-round feeling of springtime.

Depending on your climate and gardening experience, it is important to create an appropriate plan for your flower bed layout. For example, do you want annuals that will bloom during the peak of summer or perennials that have a shorter bloom time but return again the following year? Here are 15 of the best plants for flower beds.

Some of the plants on this list are toxic to pets. For more information about the safety of specific plants, consult the ASPCA's searchable database.

Also known as pot marigolds, calendula plants are about as bright and cheery as it gets. Plant these sun-loving annuals in the early spring along with bulb plants like tulips and daffodils, and pinch back the long stems of young plants to promote more bushy growth with more blossoms.

Calendula marigolds have been historically used for culinary purposes.

  • USDA Growing Zones: 2 to 11.
  • Sun Exposure: Partial to full sun.
  • Soil Needs: Average, well-drained soil.

Classic and romantic, the soft petals of geranium flowers have been a flower bed staple for over a century. While the plants may look delicate, they actually are quite hardy and enjoy hot weather, even holding up in dry conditions.

Most varieties are grown as annuals that will bloom all season during the summer, though there are some perennial versions that can grow in either sun or shade. 

  • USDA Growing Zones: 10 and 11.
  • Sun Exposure: Full sun.
  • Soil Needs: Well-drained.

Ornamental Sage (Salvia)

There are nearly 1,000 different varieties of ornamental sage, and while they come in both annual and perennial types, almost all of them share the same signature jewel-toned colors ranging from blue and purple to red and white.

These long-stemmed flowers are also extremely drought resistant and can spread rapidly if left unchecked. Be aware, however, that most of the ornamental versions are inedible, unlike classic culinary sage leaves. 

  • USDA Growing Zones: 5 to 10.
  • Sun Exposure: Full sun or partial shade.
  • Soil Needs: Slightly acidic to neutral, well-drained soil.

When choosing the best plants to include in your flower bed, it helps to plant with a purpose. Native to North America, the bee balm plant (also known as monarda) is a favorite of important pollinators like bees, butterflies, and hummingbirds.

Its unique, open-shaped flowers have tubular petals in shades of red, pink, purple, and white. Best of all, bee balm plants are perennial, so they will come back every year from July until the end of summer.

  • USDA Growing Zones: 3 to 9.
  • Sun Exposure: Full sun.
  • Soil Needs: Rich, well-draining soil.

Garden Cosmos (Cosmos bipinnatus)

Another favorite of pollinators, cosmos have sweet saucer-shaped flowers that come in shades of red, orange, white, pink, and bicolor. They look similar to a daisy. The bright flowers are contrasted by their thick deep-green foliage with feathery stalks that can reach up to 6 feet in height.

Usually grown from seed, varieties of cosmos come in both annual and perennial, and are easy enough to maintain that they’re often used in children’s gardens to help teach them about plants.

  • USDA Growing Zones: 2 to 11.
  • Sun Exposure: Full sun.
  • Soil Needs: well-draining, neutral to alkaline soils.

Garden Mums (Chrysanthemum)

Perfect for an autumn garden, chrysanthemums are herbaceous perennials that are a welcomed addition to flower beds after the summer flowers have gone. Depending on the variety, garden mums will bloom between September and October when planted in early spring, and are often pinched back to make them bushier and thicker.

These plants require a lot of water, however, and soil should remain moist but not soggy.

  • USDA Growing Zones: 4 to 9. 
  • Sun Exposure: Full sun.
  • Soil Needs: Rich, moist, and well-draining.

Yarrow (Achillea millefolium)

One of the easiest to care for on the list, the yarrow plant is a flowering perennial that doesn’t need to be fertilized and only needs watering during periods of drought. The blossoms range from golden yellow to white, with groupings of tightly packed tiny flowers that tend to tower over its foliage.

  • USDA Growing Zones: 3 to 9.
  • Sun Exposure: Full sun.
  • Soil Needs: Sandy and well-draining.

Black-Eyed Susans (Rudbeckia hirta)

Known for the dark stamens that stick out of petals colored with red, orange, and yellow, black-eyed Susans make a statement in a flower bed. The perennials require very little maintenance and are both deer resistant and drought tolerant, with the added perk of attracting birds to your garden.

As they tend to bloom as summer flowers begin to fade, black-eyed Susans are good indicators of fall.  

  • USDA Growing Zones: 3 to 11.
  • Sun Exposure: Full sun to light shade.
  • Soil Needs: Neutral soil pH.

Peony (Paeonia)

The fluffy flowers of the peony plant bloom from late spring through early summer, coming back year after year for up to a century when properly cared for.

These plants are great for flower beds since they are so resilient and fragrant, adding substantial pops of white, pink, red, purple, and yellow colors.

Give peonies plenty of room to grow as they are bound to be around for a while, growing up to 5 feet across within their first 10 years of life.

  • USDA Growing Zones: 3 to 8.
  • Sun Exposure: Full sun.
  • Soil Needs: Well-drained.

Zinnias (Zinnia)

Because zinnias are native to grasslands, they are extremely tough and can tolerate drought and poor soil very well; they also prefer full sun for the same reason. With the exception of blue, zinnias come in virtually all colors, shapes, and sizes, reaching widths from 12 to 18 inches and blooming in either summer or fall.

Be sure to provide well-draining soil when first planting zinnias, as they are prone to rotting if the ground gets too cool or wet.

  • USDA Growing Zones: 3 to 11.
  • Sun Exposure: Full sun.
  • Soil Needs: Fertile, well-drained soil.

Daylilies (Hemerocallis)

While daylilies are relatively easy to maintain, most types have flowers that only last one day (as the name suggests) so many gardeners choose to grow a variety of different ones to provide a longer display of color. Other varieties rebloom continuously for months or twice a year.

Also known for their pleasant scent, daylilies have long delicate petals that come in shades of yellow, orange, red, pink, purple, white, and peach.

Note that some daylilies are considered invasive in some parts of North America. Before planting this flower, check with your regional extension office or local gardening center.

  • USDA Growing Zones: 4 to 9.
  • Sun Exposure: Full sun or partial shade.
  • Soil Needs: Slightly moist, well-drained.

Pansies (Viola tricolor)

Pansies have a short growing season, but that doesn’t mean they should be counted out when it comes to your flower bed.

These small soft flowers with heart-shaped petals come in multicolored combinations of white, yellow, purple, and blue. Most bloom from spring to early summer and are compact plants that grow close to the ground, perfect for edging into smaller areas or in between pathways.

  • USDA Growing Zones: 2 to 9.
  • Sun Exposure: Full sun to partial shade.
  • Soil Needs: Slightly acidic, well-draining, and loose.

Coneflowers (Echinacea)

You’ve probably heard of perennial coneflowers, otherwise known as echinacea. Native to North America, coneflower foliage has a lovely blue-green hue and the flowers boast a pinkish-purple color (though there are more recently bred variations ranging from red and orange to white and yellow).

  • USDA Growing Zones: 3 to 9.
  • Sun Exposure: Full sun.
  • Soil Needs: Well-drained, neutral soil.

Bearded Iris (Iris germanica)

Probably the most popular plant in the iris family, the bearded iris is easy to grow in flower beds as long as it's given well-drained soil and plenty of sun (at least six to eight hours per day).

Bearded irises have overlapping, crinkly petals that look similar to tissue paper flowers and should be planted in the late summer. There is a wide variety of colors and sizes and some are even re-bloomers, meaning they will come back twice in one season. 

  • USDA Growing Zones: 3 to 9.
  • Sun Exposure: Full sun.
  • Soil Needs: Neutral, well-draining soil.

Garden Phlox (Phlox paniculata)

Native to the East and Central United States, phlox plants will make a low-maintenance, fragrant, bountiful addition to your perennial flower bed.

Although they are native to the U.S., certain varieties have been hybridized to withstand drought and resist mildew. These plants grow low to the ground but typically spread slowly (up to 2 feet across), so they won’t get too out of control if you’re using them as ground cover.

  • USDA Growing Zones: 2 to 9.
  • Sun Exposure: Full sun to partial shade.
  • Soil Needs: Moist, rich soil.

To check if a plant is considered invasive in your area, go to the National Invasive Species Information Center or speak with your regional extension office or local gardening center.
