Common Questions
Tweedia questions
What zones can Tweedia grow in?
Tweedia 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 Tweedia deer resistant?
Not reliably. Deer may browse Tweedia, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Tweedia bloom?
Tweedia 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 Tweedia need full sun?
Tweedia does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Tweedia drought tolerant?
Yes — once established (usually after the first full season), Tweedia handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
