Dry gravelly soils in rock gardens and borders are the perfect sites for drought-tolerant prickly poppy. The large open flowers with central rings of gold stamens attract native bees, while the jagged foliage with spines effectively repels deer for a successful, low-maintenance native garden. Deadhead spent flowers regularly to keep your poppy blooming. However, leaving a few flowers to self-sow helps ensure a new season of bloom. With their ability to thrive in hot, dry conditions, prickly poppies can be a stunning addition to dry gardens.
