Frequently asked questions
What zone does creeping phlox grow in?
Creeping phlox is hardy in USDA zones 3 to 9. Outside that range it struggles with the winter. Find your zone by ZIP code.

Full sun. Full sun means at least six hours of direct sun a day; part shade means about three to six.
Hardiness ranges, light and size are typical figures from university extension services and botanic garden plant records; a named variety can differ, so check its tag. Planting dates come from each zone's median frost dates (NOAA 1991 to 2020 climate normals) and the timing rules in how we check.
