Common Questions

Montbretia questions

What zones can Montbretia grow in?

Montbretia is hardy in USDA Zones 5–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Montbretia deer resistant?

Yes — Montbretia is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Montbretia bloom?

Montbretia 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 Montbretia need full sun?

Montbretia does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Montbretia drought tolerant?
