Longleaf phlox Phlox longifolia subsp. brevifolia
ABOUT
The plant, commonly known as Longleaf Phlox, typically exhibits a dense, mat-forming growth habit, creating clusters of foliage close to the ground. Its leaves are narrow and needle-like, with a strong green color, and they often remain relatively small. The plant's leaves are sometimes hairy or sticky, giving them a textured feel. During its blooming period, Longleaf Phlox produces a profusion of flowers. These blossoms are carried in clusters on top of short, upright stems that rise from the mat of foliage. The flowers can vary in color, commonly displaying shades of pink, purple, or white, each with a small, tubular shape that flares open into five distinct, rounded lobes. In the center of each flower, there's typically a darker eye or a more vividly patterned center that adds contrast to the blooms. The roots are fibrous and may form a tight network beneath the plant, helping it to anchor in the soil and spread. Its overall appearance is one of dense greenery punctuated by abundant, colorful flowers which can add a splash of color to a garden setting.

WaterFor Phlox longifolia subsp. brevifolia, commonly known as Longleaf Phlox, it’s important to maintain consistent moisture but avoid overwatering. During the growing season, water the plant once a week with approximately one gallon of water, making sure it penetrates the soil deeply to encourage strong root development. The amount of water may need to be adjusted depending on climate conditions; during hot, dry periods, additional water may be necessary. Reduce watering in the fall and winter when the plant is dormant. Ensure good drainage to prevent root rot, as this species can be susceptible to excessive moisture.
LightLongleaf Phlox thrives best in full sun to partial shade conditions. The ideal spot for this plant is an area that receives at least 6 hours of direct sunlight per day but is sheltered from the harshest midday sun. It can tolerate some light afternoon shade, especially in hotter climates, which can help protect the plant from excessive heat stress.
TemperatureLongleaf Phlox is hardy and can tolerate a range of temperatures, but it prefers mild to warm conditions. The ideal temperature range for this plant is between 60 and 85 degrees Fahrenheit. It can survive minimum temperatures down to 20 degrees Fahrenheit but sustained frost or extreme heat can damage or kill the plant. During the growing season, keep temperatures within the ideal range to encourage robust growth and flowering.
PruningLongleaf Phlox benefits from pruning to promote bushier growth, enhance flowering, and prevent disease. Prune in early spring by cutting back the plant by about one-third to stimulate new growth. Deadheading, or removing spent flowers, throughout the flowering season also encourages more blooms and prevents self-seeding. After blooming has finished, prune the plant back to maintain its shape and size. The best time for major pruning is early spring or immediately after the flowering period.
CleaningAs needed
SoilLong-leaf phlox thrives in well-draining soil with a neutral to slightly alkaline pH between 6.5 and 7.5. A mix of garden soil, compost, and coarse sand or perlite can promote good drainage and fertility. Ensure the soil is rich in organic matter to support its growth.
RepottingLong-leaf phlox generally does not require frequent repotting and can be repotted every 2 to 3 years. It is best to repot in the spring, just before the onset of the growing season, allowing the plant to establish in its new container.
Humidity & MistingLong-leaf phlox prefers moderate humidity levels but is quite adaptable and can tolerate the varying humidity conditions typical of many outdoor environments. It does not have specific high humidity requirements.
Suitable locationsIndoor
Ensure bright light, cool temperatures, and good airflow for indoor long-leaf phlox.
Outdoor
Plant in well-draining soil, full sun to partial shade, and water regularly.

Life cyclePhlox longifolia subsp. brevifolia, commonly known as the Longleaf Phlox, typically begins its life cycle as a seed, which germinates in the suitable environmental conditions of late fall to early spring. After germination, the seedling emerges and develops into a rosette of leaves close to the ground during its initial growth stage. As the plant matures, it starts to elongate its stems, leaves become more developed, and it enters the vegetative growth phase. The flowering stage occurs next, usually in late spring to early summer, where the plant produces clusters of tubular, fragrant flowers that can be pink, purple, or white. After pollination by insects, the flowers develop into fruit capsules that contain small seeds, which are subsequently dispersed by wind, water, or animals. Finally, the Longleaf Phlox enters a period of dormancy in late fall or early winter where it may die back to the ground, with the roots or basal rosette surviving until the next growing season.
PropogationPropogation time
Spring
Propogation: The most popular method of propagating the Narrowleaf phlox, Phlox longifolia subsp. brevifolia, is through cuttings. Cuttings are typically taken in late spring or early summer when the plant is actively growing. A cutting of about 4 to 6 inches (approximately 10 to 15 centimeters) is snipped just below a node, which is the point on the stem where leaves are attached. The lower leaves are removed, and the cut end of the stem is dipped in rooting hormone to encourage root development. The cutting is then planted in a mixture of moist, well-draining potting soil and sand to provide the right balance of moisture and aeration. It's important to place the cutting in indirect light and keep the soil consistently moist but not waterlogged. Roots usually develop within 3 to 4 weeks, after which the new plant can be gradually acclimated to outdoor conditions before transplanting.
