Summer is a season that breeds fun and leisure, and it's only natural that a flower gardener should want fresh blooms to provide a seasonal backdrop. While it may be far easier to find spring blooming flowers, there are still a number of lovely summer blooming flowers that will soak up the hot sun.
Growing up to 5 feet tall, canna lily (Canna x generalis), also called garden lily, is a stately perennial notable for its fleshy green foliage and silky, breezy blooms, which come in colors ranging from orange to yellow, red, pink and white. It is a summer flowering plant that produces its showy blossoms until well into autumn. The plant can be cultivated in full sunlight in USDA zones 8B to 10B. Canna lily is a versatile border or container plant that is adaptable to a range of different soil types, so long as it's watered frequently. Canna lilies grow in wet, even water-logged soils, making them a good choice for pond edges.
Black-eyed Susan (Rudbeckia hirta) is a short-lived member of the aster/daisy family that grows to an average height of about 3 feet. A native of North America, it is a popular summer flower that produces cheery yellow flowers throughout the season. The plant boasts dense, bushy green foliage. It is best cultivated in USDA zones 3 to 10 in well-drained, even poor, soils. The plant will often grow in disturbed soils, and can sometimes be seen along hot dusty roadsides. Black-eyed Susan is drought tolerant, though it will produce its best blooms if watered on a regular basis, especially during the summer.
A native of India, Sri Lanka and Malaysia, the pagoda flower (Clerodendrum paniculatum) is a flowering shrub that is evergreen in warm climates. The plant reaches an average height of between 3 and 5 feet, sporting heart-shaped green leaves and tubular red and white flowers that are notable for their needle-thin red stamens. The plant produces its distinct blooms in summer, and the flowers often continue on until mid-autumn. Pagoda flower can be cultivated in USDA zones 8 to 11. The shrub should be cultivated in full sunlight, though it will tolerate some shade. A rich soil is ideal, and the shrub should be watered frequently during the summer to keep it looking fresh and healthy.
