Common Questions
Cosmos Flamingo questions
What zones can Cosmos Flamingo grow in?
Cosmos Flamingo is hardy in USDA Zones 7–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Cosmos Flamingo deer resistant?
Not reliably. Deer may browse Cosmos Flamingo, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Cosmos Flamingo bloom?
Cosmos Flamingo typically blooms in mid-summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Cosmos Flamingo need full sun?
Cosmos Flamingo does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Cosmos Flamingo drought tolerant?
Yes — once established (usually after the first full season), Cosmos Flamingo handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
