June brings to the garden long summer days filled with blazing summer temperatures. As many flowers and plants die down for the season, summer-loving flowers emerge to light up the garden with color and texture. Oftentimes summer flowers are drought tolerant, creating a versatile and hardy plant to grow throughout the garden. Grown in a wide range of colors and sizes, they create a showy display to the garden while complementing existing flowers.
Daylily (Hemerocalis fulva) is a perennial flower with a moderate growth rate and clumping growth habit. Blooming all summer long, daylilies create a striking garden design. Growing 3 to 6 feet tall, they have an upward facing flowerhead that, as the name indicates, blooms only one day. Daylilies grow in a wide variety of colors including pink, purple, orange, peach and deep red. Some daylilies are variegated with a contrasting throat that adds vibrancy to the petals. The leafless flower stem of daylilies holds the sword-like leaves and the long, arching leaves cascade down to the garden floor. Daylilies require full sun to part shade and tolerate a range of soil types. Drought-tolerant daylilies grow best in nutrient-laden soil. To retain moisture, especially during the hot summer months, mulch the daylily with organic matter like leaves. To grow in other areas of the garden, divide them in spring or fall. Plant daylilies in U.S. Department of Agriculture (USDA) hardiness zones 3 to 10.
Cosmic Red Cosmos
Cosmic red cosmos (Cosmos sulfureus "Cosmic Red") is an annual flower with a clumping growth habit and rapid growth rate. Growing 6 to 12 inches tall and wide, cosmic red cosmos flowers emerge in June to light up the landscape with color. The scarlet red flowers on cosmic red cosmos contrast with the yellow centers and not surprisingly attract butterflies to the garden. Drought and heat tolerant, they have bright green, fern-like foliage that holds up the saucer-shaped blooms. Cosmos are ideal flowers to grow as a ground cover for their low-growing nature or tucked into a container with other fiery or "hot" flowers. They require full sun and moist, well-drained soil that is nutrient rich. To extend the flowering season, deadhead or remove the spent blooms as soon as they are visible. They are hardy in all USDA zones.
Lance-leaved coreopsis (Coreopsis lanceolata) is a perennial flower with a vigorous growth rate and clump-like habit. Emerging in early summer to last through the season, lance-leaved coreopsis has yellow petals with toothed edging. Drought tolerant, coreopsis is ideal grown in a cutting garden for its interesting blooms and upright foliage. Lance-leaved coreopsis is tolerant of a wide range of soil varieties, creating a hardy and adaptable summer flower. A butterfly attractant, lance-leaved coreopsis grows 1 to 3 feet tall and wide. They require full sun to part shade. Plant in USDA zones 4 to 9.
