Tall garden phlox (Phlox paniculata) does have the potential to spread. This native perennial plant features an upright growth habit and typically reaches heights of 2 to 4 feet (60-120 cm). However, in terms of spread, it usually extends to about 2 to 3 feet (60-90 cm).
One of the factors that contribute to the spread of tall garden phlox is its ability to produce new shoots from underground rhizomes. These rhizomes, which are horizontal underground stems, can give rise to new plants and help the phlox spread throughout the garden. This can be both a positive and negative aspect, depending on your preferences and the available space in your garden.
In terms of foliage, tall garden phlox has narrow, elliptical, dark green leaves. These leaves provide an attractive backdrop to the plant’s vibrant blooms. The foliage and overall growth habit of tall garden phlox make it a visually appealing addition to any garden or landscape.
When it comes to the flowers, tall garden phlox produces large, showy clusters of blooms in a wide range of colors including white, pink, purple, and red. These flowers are fragrant and attract butterflies, hummingbirds, and bees, adding not only beauty but also biodiversity to your garden.
In terms of care, tall garden phlox thrives in full sun to partial shade conditions. It prefers well-drained soil and benefits from regular watering, especially during dry spells. Deadheading spent blooms can help promote continuous blooming and prevent self-seeding, which can also contribute to the plant’s spread.
While tall garden phlox has the potential to spread, it is not considered invasive in most areas. However, it is always a good idea to keep an eye on its growth and take steps to contain it if needed. This can be done by dividing clumps every few years to control its spread or by using physical barriers such as edging or containers.
Tall garden phlox is a native perennial plant that can spread through underground rhizomes. Its upright growth habit, attractive foliage, and vibrant blooms make it a popular choice for gardeners looking to add color and beauty to their landscapes. While it has the potential to spread, it is not typically invasive and can be easily managed with proper care and maintenance.
