Tall Phlox - Phlox Paniculata
Tall Phlox offers an array of colors during the summer months. This plant can bloom for six weeks or longer. Some start to bloom in mid-summer while others do not begin until late in August. Colors include white, red, purple, lavender, rose, and pink. Some are even a blend of two colors with a center of another color. The flowers have five lobes and grow in clumps at the top of the plant. The plants generally get from 2 to 4 feet tall, growing upright on a stiff stem. Leaves are a deep green and are lance-shaped. When the stems on the plant are approximately six inches tall, pinch off all but five or six as well as the tips of these stems. This will allow the plant to grow more prominent clusters of blooms.
Tall Phlox will flourish in areas that receive full sun but will grow in lightly shaded spots as well. Too much shade will prevent the plants from producing as many blooms, and the quality of the flowers will suffer. They should not be grown under trees or near large hedges. Competition for nutrients and moisture from the soil can cause a problem for Tall Phlox. These plants will do well when planted in areas with good drainage and watered on a regular basis. It is best to moisten the soil around the Tall Phlox rather than the plant itself. This helps to prevent disease. Fertilizer is recommended in the spring as new growth appears. Mulch will help to keep the soil around the plant fresh and helps to retain moisture. Tall Phlox will grow from the District of Columbia to the panhandle of Florida. When the blooms start to fade, removing the flowers will help to keep blooms the color initially is chosen. It is sometimes possible to get the Tall Phlox to bloom twice by fertilizing again after the first blooms are gone.
Tall phlox is a favorite perennial of gardeners everywhere. These gorgeous flowers are also adored by hummingbirds and butterflies alike, so be sure to add this flower to your landscaping if you are trying to attract them to your yard. The bulb comes in an assortment of different colors like deep red, bubblegum pink, hot raspberry pink, peach orange, royal purple, light lavender, and bright pure white. They can tolerate clay, loamy, or sandy soil, but make sure it drains well. The foliage can range from a bright green to a dark green and grows in the pattern of an X up the stem of the plant making it very distinctive from other plants in your garden adding interest and variety. There is also some tall phlox which has variegated foliage for the genuinely adventurous gardener. The flower heads form a cluster at the top of the plant stem, which has dozens of little individual five-petaled flowers. They can be cut for flower arrangements indoors if desired. The fragrance of the flower ranges from sweet to spicy depending upon the variety you choose. The flowers can also be deadheaded to encourage more blooms from the plant. If you allow the flower blooms to be pollinated by bees, butterflies, or hummingbirds, they will go to seed. Seeds that drop from the original plant will enable the plant to spread to surrounding areas. The spread area can range from 18-24 inches. With so many colors and variety of tall phlox available no wonder it is a favorite addition to gardeners everywhere. Be sure to add some to your landscaping today. The bees, butterflies, and hummingbirds of your area will thank you!
