Common Questions
Boston Ivy questions
What zones can Boston Ivy grow in?
Boston Ivy is hardy in USDA Zones 4–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Boston Ivy deer resistant?
Yes — Boston Ivy is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Boston Ivy bloom?
Boston Ivy typically blooms in early to mid-summer through early fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Boston Ivy need full sun?
Boston Ivy does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Boston Ivy drought tolerant?
Yes — once established (usually after the first full season), Boston Ivy handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
