Good flowers for summer come in varying shapes and sizes that all have one thing in common: they are well-suited to warmer temperatures and display flowers when many spring flowers have already finished their bloom. Good summer flowers thrive in heat and add color and interest to your garden well into the month of August.
False sunflowers (Heliopsis helianthoides) are low maintenance plants that flower in late summer, continuing into early fall, and display vibrant yellow to orange blooms. Thriving in full sunlight to partial shade, false sunflowers grow to a height of 3 to 4 feet, according to the Iowa State University Extension. Once the roots of false sunflowers have been established, the plant can survive on natural water supply from areas with adequate rainfall, making it a perennial with less challenging care requirements, explains Sedgwick County K-State Research and Extension.
Bigleaf goldenrays (Ligularia dentata) are a well-suited addition to summer gardens with wet sites. Bloom times is during midsummer through early in the fall season. Displaying yellow-orange flowers, this perennial prefers cooler temperatures and thrives in partial shade and moist to wet soil. Bigleaf goldenrays grow to a height of 3 to 4 feet, according to the Iowa State University Extension. Additionally, these perennials are well-suited for gardens often pestered by deer; bigleaf goldenrays have a high resistance to deer, explains the Rutgers Cooperative Extension.
Morning Glories 'Grandpa Ott'
Grandpa ott morning glories (Ipomoea 'Grandpa Ott') are annual vines that display purple flared flowers with "pink throats" that bloom through August. Thriving in full sun to partial shade and nearly any soil type, this annual vine grows quickly, making it a good summer flower with little guesswork, explains the University of Illinois Extension. Grandpa ott morning glory vines reach a climbing height of 12 feet, according to the Iowa State University Extension.
Fleabane (Erigeron hybrids) provides a way to add color to your summer rock garden or to an area with sandy soil. Fleabane plants bloom in the middle of the summer season and continue into fall, displaying flowers in pink, violet or purple with yellow throats. Thriving in full sunlight, this summer-blooming plant prefers moist, well-drained soil and grows to a height and width of approximately 2 feet, according to the Iowa State University Extension.
Azure salvia (Salvia azurea) will add a touch of blue to your summer garden; azure salvia blooms late in the summer season and during fall. With a display of showy blue flowers, this perennial thrives in full sunlight and prefers well-drained soil. Azure salvia grows to a height of approximately 4 feet when in bloom, according to the Iowa State University Extension.
