English ivy
Hedera helix · Araliaceae
English ivy (Hedera helix) is a perennial vine in the Araliaceae family. It is introduced to North America rather than native. USDA records it as hardy in zone 4 and warmer, down to about -23°F.
⚠ Invasive or noxious status. USDA lists this plant with an invasive or noxious weed status somewhere in its range. Check your state's noxious weed list before planting it — in some states it is illegal to sell or plant.

Growing conditions
It tolerates full shade. USDA rates it as having moderate water needs. Its drought tolerance is rated low. It will not tolerate waterlogged soil — USDA rates its anaerobic tolerance as none. It is recorded on soils from pH 5.2 to 7.8 — a broad range that spans acidic through mildly alkaline ground. Its cold limit is zone 4.
Size and growth
At maturity it reaches about 5 ft, making it roughly waist to chest height. It grows at a moderate rate.
Bloom period
USDA records a bloom period of May through June.
A flowering date, not a pollinator rating.
Foliage, flower and season
Summer foliage is green, coarse in texture. Its flowers are not conspicuous — a plant for form and foliage. Its active growth period is spring and summer. USDA rates its lifespan as long.
What the site needs to provide
USDA records it across sites receiving 28 to 65 inches of annual precipitation. It needs at least 160 frost-free days to finish its season. It roots to at least 12 inches. Fertility requirement: medium.
Propagating it
Propagate it from cuttings, bare root and container stock. It spreads vegetatively at a rapid rate.
Resilience and wildlife
Browsing animals rate it barely palatable — the sourced basis for calling it deer-resistant. Its fire tolerance is rated high. Its growth form is recorded as stoloniferous.
Role in a guild
Climber. In a layered planting this is it uses other plants or structures for vertical support rather than standing on its own. The layer is derived by a fixed rule from growth habit and mature height.

Where this data comes from
Every value on this page comes from the USDA PLANTS database record for symbol HEHE, or is computed from those values by a fixed rule. Nothing here is estimated or model-generated. Where USDA publishes no value, this page omits the claim rather than filling the gap.
