Pink Summer Flowers

By Melody Lee ; Updated September 21, 2017

Pink flowers add a splash of color to a summer garden with hues that range from bright pink to soft pink. Brighter colored flowers can be grown in the sun, but lighter colored flowers should be grown in the shade so the sunlight does not fade their colors.

Annual and perennial plants have pink flowers that bloom in the summer. Annuals usually bloom all season long, from spring to fall. Perennials typically bloom for a shorter period of time or bloom in short flushes during the summer.

Annuals for Sun

Geraniums (Pelargonium x hortorum) have solid or striped pink flowers, and grow in a mound 12 to 24 inches tall, and 12 inches wide.

Zinnias have single, double, domed or ball-shaped blooms in all shades of pink. They grow 6 to 36 inches tall, and 8 to 12 inches wide. Clusters of medium pink flowers top the stems of pentas, which grow 12 to 36 inches tall, and 24 inches wide. Zinnias and pentas have upright forms, which may need staking.

Cleome has clusters of pink spider-like flowers on 3- to 6-foot-tall stems, and grows 15 to 18 inches wide. It is a sturdy plant and usually does not need staking.

Annuals for Sun to Partial Shade

Bachelor Buttons (Centaurea cyanus) grow 12 to 36 inches tall, and 12 to 14 inches wide. They have pom-pom shaped flowers of light or medium pink. Petunias are sprawling plants that grow 12 to 36 inches tall, and 24 inches wide and have trumpet-shaped flowers of pale to bright pink.

Begonias grow 6 to 12 inches tall and wide and have medium to dark pink blooms. Impatiens have pale pink, rose or fuchsia flowers, and grow 8 to 24 inches tall, and 10 to 12 inches wide. Begonias and Impatiens grow better in with afternoon shade in hot climates.

Perennials for Sun

Gladiolas have 2 to 4 foot long spear-shaped leaves and spikes of pink flowers in several shades, while Dahlias form 2 to 3 foot tall and wide mounds and have single, double, pom-pom, or domed flowers. Gladiolas and Dahlias grow from tubers and may have to be lifted in the winter in colder climates. The Whirling Butterfly plant (Gaura lindheimer) has an open form that grows 2 to 4 feet tall and wide, with small pink flowers that resemble butterflies. Lantanas are bushy perennials that grow 2 to 4 feet tall and wide with clusters of pink blooms.

Perennials for Sun to Partial Shade

Daylilies (Hemerocallus spp.) and Canna Lilies grow 2 to 4 feet tall. Daylilies have trumpet-shaped flowers, while Canna Lilies have large asymmetrical flowers. Daylilies and Canna Lilies prefer more sun than shade.

Astilbes have pastel to medium pink feathery flower plumes and grow 2 feet tall. Tuberous Begonias form 2 foot mounds and have blooms that resemble miniature roses. Astilbes and Tuberous Begonias prefer more shade, especially in hot climates.
