Flowers That Bloom All Summer

By S.F. Heron ; Updated September 21, 2017

Flowers that bloom all summer form the anchor to the garden bed. Many plants bloom for a 3 to 4 week period of time and simply offer beautiful foliage for the rest of the season. A few standout plants such as monarda, delphinium, roses, verbena and tickseed perform the hard task of blooming throughout the summer growing season. These flowering plants all require regular dead-heading to remove spent blossoms.

Deadheading promotes new bud production and encourages plant energy to focus on flower production rather than seed creation. Perennials and annuals won't bloom all summer with regular care, adequate water and fertilization.

Bee Balm

Bee balm or monarda offers a uniquely shaped flower in a variety of colors. Bee balm comes in white, rose deep pink and purple shades. This flower blooms continually through the summer and grows to a height of 2 to 3 feet. Bee balm flowers resemble a pom pom with spiked petals shooting out randomly all over the flower. This plant attracts abundant bees and butterflies as a beautiful addition to any garden.


Delphiniums offer the gardener a tall stalk and bell-shaped flowers in brilliant purple, white and pink. Imagine dozens of bells lying side by side to form a stately ladder-like floral display Delphinium prefer rich soil and good drainage. These tall plants might require some assistance with staking to keep the flowers upright. Delphiniums work well as background plantings to line a fence line or rear garden area. Fertilize monthly to encourage healthy stem growth and abundant blooming through the growing season.


The tickseed (coreopsis) presents a unique leaf and flower for use as a garden accent throughout the summer. Tickseed has spiked leaves resembling an asparagus fern with vibrant yellow flowers. Flowers grow to 2 to 3 feet in height and thrive in partial to full sun. This plant will flower continually throughout the summer with adequate water and fertilizer. Make sure to deadhead spent flowers to direct the plant's energy toward rejuvenation and future flower production.


Verbena serves as both an annual and perennial depending on the planting zone. This plant thrives in the heat and produces masses of small flowers in a variety of colors. Dark purple and pink varieties work well in container gardens and hanging planters. Verbena features a vine-like growth pattern than spreads this planter to trail over container edges or to fill garden spaces. This plant prefers full sun and can tolerate mild pruning to increase plant vigor. Make sure to monitor soil moisture since this directly affects the length and amount of blooms.


Any of the many varieties of roses deliver consistent color and dramatic foliage throughout the summer. Roses bloom contiguously with proper pruning and fertilization. Among the many rose varieties are climbers, tea roses and shrub roses that offer continual color through the summer months.
