Prairie Moon Nursery Garden Phlox

Garden Phlox seeds require a period of cold and moisture to break dormancy, mimicking the natural winter cycle they experience in the wild. You will need to simulate this by placing the seeds in a damp medium in your refrigerator for several weeks before planting, or by sowing them outdoors in the fall to let nature do the work.

No, this species is specifically adapted to wet to medium-wet soil conditions. It will likely struggle or fail to thrive in dry, well-draining garden beds, so it is best suited for rain gardens, low-lying areas, or consistently moist borders.

You should space these plants 24 to 36 inches apart. This spacing allows for proper air circulation, which is crucial for preventing powdery mildew, a common issue for many phlox varieties.

It blooms from July through September, making it a reliable late-season performer. While it doesn't bloom in early spring or early summer, it is an excellent choice for extending color in your landscape when many other flowers have finished.

No, this is a native perennial species that typically grows in clumps rather than spreading aggressively via runners. It is well-behaved in a garden setting and supports local pollinators without taking over your flower beds.

This phlox prefers full sun to partial sun exposure. While it may tolerate some light shade, you will get the best bloom production and strongest stems with at least six hours of direct sunlight daily.
