Flower gardens give a landscape color and beauty throughout the spring, summer and fall. Some flowers appear in several gardens. These are the common, standard flowers that are available from many garden stores as seeds, bulbs or transplants. Common flowers give a garden a homey feeling.
Common sunflowers (Helianthus annuus) are popular annuals grown in many gardens. They produce large, showy flowers from midsummer to midfall. Sunflowers often reach eight feet in height and need staking to provide support to stay upright. Sunflowers tend to loose their heart shaped leaves on the lower half of their stems, so plant shorter annuals around their base to disguise their bare stems.
Cornflowers (Centaurea cyanus) are also known as bachelor’s buttons. This perennial reaches 12 to 30 inches in height. Flowers appear throughout the summer in white, blue, purple, pink and red shades. Deadhead the dying blossoms to promote the production of more flowers. Cornflowers grow well when sown directly in the garden.
Daylilies (Hemerocallis hybrids) are popular perennials that stay in bloom for more than a month at a time. Individual blossoms last only 24 hours, but the daylily continuously produces buds throughout the summer. Depending on the variety, daylilies reach one to five feet in height. Daylilies come in nearly every color imaginable.
Marigolds (Tagetes hybrids) add bright, hot colors to a garden. They produce two to four inch flowers in yellow, orange and red on top of 18 to 36 inch stems. Marigolds are commonly grown as borders around a flowerbed and are known for their insect pest repellent properties.
Pansies (Viola x wittrockiana) are a cool weather annual. They produce large two to five inch flowers in the spring that are white, pink, red, orange, yellow, purple, blue and near black with yellow centers. Pansies grow six to eight inches tall with narrow, green leaves. They are used as fillers in gardens and as container plants.
Siberian iris (Iris sibirica) grows one to three feet tall and bloom in white, cream, yellow, blue, violet and purple colors. Irises form sword-like leaves arranged in fans. Iris bloom in early summer, and are heat and cold tolerant. Irises are commonly used with perennials, ornamental grasses and ferns.
