Did You Know?
Despite its delicate appearance, Phlox subulata is so cold-hardy it can bloom while partially covered in snow in its native North American range, with flowers opening at temperatures barely above freezing—making it one of the few true alpine groundcovers that also thrives in South African gardens at altitude.
