Though spring is commonly thought of as the season of flowers, there are still a number of lovely flowering plants that produce their blooms during the hot summer season. Flowers add more color to an already fun and relaxing season, offering a little extra life to the garden. There plenty of summer flowers to grow that require only a minimal amount of care.
Garden verbena (Verbena X hybrida) is a garden cultivar that is commonly grown as an annual. The plant boasts green wiry foliage accented by clusters of silky flowers, which range in color from purple to blue and white. The plant is usually grown as an annual in USDA zones 5 to 9, though it can be grown as a perennial in 8, 9 or 10. Garden verbena grows best in full sunlight (with afternoon shade in hot climates), in fertile well drained soil. Water the plant frequently for best results.
Garden phlox (Phlox paniculata) is an upright flowering perennial native to the Eastern United states. The plant sports dark green foliage and tiny clusters of flowers, which range in color from white to hot pink and pale lavender depending on cultivar. Excellent for borders, as well as butterfly gardens, garden phlox can be used for a variety of purposes, including cut flower bouquets. To cultivate the plant, which blooms from early summer well into fall, grow in USDA zones 4 to 8 in full sun or partial shade. The plant does best in fertile, well drained soils that are watered frequently.

The plant, which blooms from mid summer until early fall, can easily be cultivated in USDA zones 5A to 9A, in neutral, well drained soil. The plant will grow in partial sun or full sunlight.
