As the summer sun shines down on the garden and the temperatures soar, many summer-loving flowers emerge to light up the garden with color. Grown in a wide range of sizes, shapes and textures, summer flowers are garden staples. Found in every color imaginable, summer bloomers are often heat and drought tolerant. Tucked along a perennial bed or border, they create nonstop vibrancy.
Hollyhock (Alcea rosea) is a perennial flower with a tall, upright stem and moderate growth rate. Growing 24 to 60 inches tall, hollyhocks bloom year after year for a long-lasting summer flower variety. The funnel-shaped flowers on hollyhocks grow along the tall, upright spike. Ideal lining the back of a flowerbed for height and color, hollyhocks create a commanding landscape presence. Flower colors on hollyhock include white, pink, purple and yellow and emerge in spring to bloom all summer and into the fall. Hollyhocks require full sun only and well-drained soil to thrive. Plant hollyhocks in U.S. Department of Agriculture (USDA) hardiness zones 5 to 9.
Zinnia (Zinnia elegans) is an annual flower that blooms through the summer to add a rainbow of color to the garden. Growing 1 to 3 feet tall and wide, zinnia blooms have a rapid growth rate to fill up the landscape in no time. The bright flowerheads come in a myriad of bright colors and are single, semi-double or double in form. Tucked along a cottage garden or lining a front flowerbed, zinnia flowers make ideal fresh-cut flowers because of their long-lasting blooms and erect stems. Deer and drought tolerant, zinnia attracts winged wildlife to the garden, such as butterflies and hummingbirds. Zinnia requires full sun only and well-drained, nutrient-rich soils. To promote a long flowering season, deadhead or remove the spent blooms as soon as they are visible. These flowers are hardy in all USDA zones.
Field poppy (Papaver rhoeas) also called corn poppy, is an annual flower that emerges in summer. Growing 1 to 3 feet tall and 6 to 12 inches wide, field poppies have a moderate growth rate. The cup-shaped flowers on field poppies are paper-thin and surround the dark centers. Field poppies have a bright red flowerhead that's perched atop the bright green, hairy leaves. Grown among a cutting garden, field poppies make ideal fresh-cut flowers. They require full sun only and deep, well-drained soil that's nutrient-rich, and they're hardy in all USDA zones.
