Common Questions
Night Phlox questions
What zones can Night Phlox grow in?
Night Phlox is hardy in USDA Zones 9–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Night Phlox deer resistant?
Yes — Night Phlox is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Night Phlox bloom?
Night Phlox typically blooms in late spring through early summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Night Phlox need full sun?
Night Phlox does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Night Phlox drought tolerant?
Yes — once established (usually after the first full season), Night Phlox handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
