The blooms of this plant come in a wide array of colors that can put on quite the show for an extended period of time in mild climates.

African marigold, Tagetes erecta
Light:
Sun
Height:
1 to 3 feet
Type:
Annual

There's nothing subtle about an African marigold, and thank goodness for that! It's a big, flamboyant, colorful punch of color for the sunny bed, border, or large container. Most are yellow, orange, or cream. Plants get up to 3 feet tall and produce huge 3-inch puffball blooms while dwarf varieties get just 1 foot tall. The mounded dark green foliage is always clean, fresh, and tidy. Grow them in a warm, sunny spot with moist, well-drained soil all summer long.

Ageratum, Ageratum houstonianum
Light:
Part Sun, Sun
Height:
From 6 inches to 3 feet
Zones:
9-10
Type:
Annual

An old-fashioned favorite annual for any garden, ageratum are tough plants that can even handle a bit of shade. Not to mention, ageratum are some of the truest blue annuals you can find! Characterized by their powder-puff blooms, these plants begin to bloom in late spring and keep the show going until the first frost. These are some rugged plants that can withstand tough soil conditions and even deer! However, take caution when planning your garden, as all parts of this plant are poisonous if ingested, so site ageratum carefully.

Amaranthus, Amaranthus
Light:
Sun
Height:
From 1 to 8 feet
Zones:
2-11
Type:
Annual

An easy-to-grow annual with a big garden presence, amaranthus is tricky to find in the garden center but can be grown from seed. It is commonly called love-lies-bleeding or tassel flower. Amaranthus gets its unusual common name from the ropelike deep magenta flower stalks. The flower stalks emerge midsummer and lengthen until the first frost. The flowers stalks hold their color as they extend 12 inches or more toward the ground.

Another type of amaranthus has the common name Joseph’s coat. Unlike love-lies-bleeding, Joseph’s coat doesn’t produce ropes of flowers. Instead, Joseph’s coat is prized for its colorful foliage. Its brightly colored leaves come in shades of red, orange, and green—or all of the above when it comes to tricolor amaranthus!

Angel's Trumpet, Brugmansia
Light:
Part Sun, Sun

9-11

A tough perennial, angelonia stands up against summer's heat and humidity with no problem, making it a hearty and colorful addition to any sunny spot.

Annual Phlox, Phlox drumondii
Light:
Sun
Height:
Under 6 inches to 3 feet
Zones:
2-11
Type:
Annual

Annual phlox is a native wildflower in areas of Texas. As such, you can guess it's a wonderfully heat- and drought-tolerant variety. In late spring and summer, it shows off clusters of red, pink, lavender, or white flowers.

Because it's easy to grow and puts on such a great display, it's a good choice for beginning gardeners who have to tackle a hot, dry spot. Remove the flower clusters as they fade to encourage more blooms and pinch the plants back in summer if they start to get leggy.

Annual Statice, Limonium
Light:
Sun
Height:
1 to 3 feet
Type:
Annual

Old-fashioned annual statice is found more often dried in crafts stores than growing in gardens. But this easy-to-grow plant is a great pick for containers or the middle of a border, especially if you want to harvest it for everlasting bouquets indoors.

Statice bears papery flowers in a wide variety of colors. The flowers dry well -- so much so they practically dry on the plant. The plant is also very drought-tolerant, so you can enjoy its blooms even if you forget to water it from time to time. In fact, statice thrives in hot, sunny spots with well-drained soil. Plant them outdoors after all danger of frost has passed.

Annual Toadflax, Linaria
Light:
Part Sun, Sun
Height:
Under 6 inches to 3 feet
Zones:
2-11
Type:
Annual

Resembling a miniature snapdragon, toadflax is a great choice to bring color to the garden early in the season when you're most starved for it. In areas with cool summers, annual toadflax blooms from spring to fall. In warmer areas, the blooms fade come hot weather. Shear them back by about half. If the weather isn't too hot, they may rebloom in fall.

Toadflax grows well in the ground, but also try it in containers, especially with pansies, bulbs, and other early-season stars.

Annual Vinca, Catharanthus roseus
Light:
Sun
Height:
From 6 inches to 3 feet
Zones:
2-11
Type:
Annual

You've gotta love annual vinca -- it really delivers. It will tolerate a wide variety of conditions and still keep it up with almost unreal-looking, glossy green leaves and pretty pink, lavender, or red flowers that look like tiny parasols.

Whether the summer is dry or wet, hot or cold, vinca plugs along unfazed. It makes a great container plant. Or plant it in a bed or border, grouping at least eight or more together for best effect.

Plant established seedlings in spring after all danger of frost has passed. Vinca withstands drought but does best with moderate moisture. Fertilize occasionally. Like impatiens, this plant tends to be "self-cleaning" and needs little deadheading.

Asparagus Fern, Asparagus
Height:
1 to 3 feet
Type:
Annual, Houseplant

This subtropical relative of edible garden asparagus is in the lily family, but its needlelike foliage give it an appearance resembling a fern. Its stems shoot up and outward, making it an excellent plant for hanging baskets. Give asparagus fern medium to bright indoor light and keep the soil uniformly moist. Plants sometimes develop small red berries, which are poisonous, so keep the berries away from children and pets.

Baby Blue-Eyes, Nemophilia
Light:
Sun
Height:
Under 6 inches to 12 inches
Type:
Annual

With exquisite little blue-and-white flowers, this charming California wildflower is one of the prettiest cool-season annuals around. It can be hard to find in garden centers, but if you do, give it a try. Plant it in early spring, a few to several weeks before your region's first-frost date. It will add much to your garden until summer's heat hits. This plant likes cool and moist conditions and stops blooming once temperatures rise.

Bachelor's Button, Centaurea cyanus
Light:
Part Sun, Sun
Height:
1 to 3 feet
Type:
Annual

Bachelor's button is a sweet little flower, reseeding freely here and there in your garden, adding a bright touch of true, clear blue wherever it chooses to sprout. This easy-growing annual produces papery flowers atop tall stems; the blooms are great for cutting and drying.

The plant is happiest in sandy loam. It doesn't need much, if any fertilizer, and tolerates drought, but prefers moderate moisture. Plant from seed directly in the garden after the last frost in your region. Space to 6-12 inches apart. Deadhead after the first flush of bloom to encourage a second flush. But if you want lots of reseeding next year, allow some flowers at some point to ripen on the plant and go to seed.

Bacopa, Sutera
Light:
Part Sun, Sun
Height:
Under 6 inches
Zones:
9-11
Type:
Annual

Still a relatively new player to the plant game, Bacopa has made a name for itself with its floriferous nature. Funnily enough, its name is actually misleading. Bacopa is not in the genus Bacopa at all, but in the genus Sutera. Naming confusion aside, you would be hard-pressed to find a plant more pristinely white for all your container planting needs.

Balsam, Impatiens balsamina
Light:
Shade
Height:
1 to 3 feet
Type:
Annual

Once a favorite of Victorian gardens, this old-fashioned annual adds an exotic, almost gaudy touch to the garden. It offers interesting, trumpet-shape blooms, mostly in shades of pink. Many selections have bicolor flowers. Balsam often self-seeds in the garden and is very easy to grow.

Plant established plants outdoors in spring after all danger of frost has passed. Balsam needs rich, well-drained soil to do best, so work in plenty of compost. (It's ideal in containers as long as you don't let the plants dry out for even a second.) Fertilize lightly but regularly.

Basil, Ocimum basilicum
Light:
Part Sun, Sun
Height:
1 to 3 feet
Type:
Annual, Herb

Basil dishes up classic Italian flavor in eye-catching bushy plants suitable for garden beds or containers. Grow this tasty beauty in a sunny spot, and you'll reap rewards of flavorful foliage in shades of green, purple, or bronze. Basil lends a distinctive taste to salads, pizza, and pasta dishes. Use small leaves whole; chop larger leaves. Add leaves to dishes just before serving for greatest taste and aroma. Basil plants are exceedingly sensitive to cold; start basil seeds indoors or plant basil outside after all danger of frost has passed.

Beefsteak Plant, Iresine
Light:
Part Sun, Shade, Sun
Height:
1 to 3 feet
Type:
Annual

Add bold, tropical notes to your yard with beefsteak plant. Don't let its common name fool you -- the plant offers beautifully variegated foliage and is incredibly adaptable, as many varieties do well in both sun and shade. It's a great pick for containers or adding a bit of drama to beds and borders.

Begonia, Begonia

Part Sun, Shade, Sun
Height:
From 6 inches to 3 feet
Zones:
7-11
Type:
Annual

Begonias have been around for ages, and with good reason: This easy-to-grow annual does well in a variety of conditions and needs little to thrive. Provide it with light shade, rich well-drained soil, ample water, and plenty of fertilizer—and you’ll be rewarded with stunning flowers and foliage.

With so many different shapes, sizes, and colors, begonias have no problem taking the spotlight in any garden setting.

Light:
Sun
Height:
Under 6 inches to 3 feet

Bidens, Bidens ferulifolia
Light:
Sun
Height:
From 6 inches to 3 feet
Zones:
8-10
Type:
Annual

Some varieties are fragrant so plant them where you can enjoy their sweet scent. Bidens likes rich, well-drained but moist soil. While it's a perennial in Zones 8-10, it's usually grown as an annual.
