Longleaf phlox is a tough, low-maintenance native wildflower that thrives in rocky or sandy soils with partial shade to full sun. Water regularly during the first season to establish roots, then reduce frequency as the plant becomes drought-adapted. It's an excellent choice for naturalistic gardens and attracts a variety of pollinators in spring.
