Tall Phlox

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.

Tall Phlox Growth

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 permit the plant to develop bigger clumps of blooms.

Where To Plant Tall Phlox

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 blooms 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.

Caring 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 water the soil around the plant 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 cool 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 chosen. It is sometimes possible to get the Tall Phlox to bloom twice by fertilizing again after the first blooms are gone. Read more Read less
