From 1 to 8 feet

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.

Sun
Height:
1 to 3 feet
Type:

Annual statice, a vivid Mediterranean flower, is noted for its papery, funnel shaped calyces that bloom in summer. The flowers are actually small and white, growing in the colorful calyces that remain long after the flowers have faded away. Annual statice works beautifully in mixed borders, rock gardens, cut flower gardens, meadows, and cutting gardens. These plants make an excellent choice for cut flowers and dried arrangements. 

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

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.

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

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
