This common ornamental species is often found spreading vegetatively from cultivation, there is little or no evidence of expansion via fruits.
There is considerable disagreement over ivy taxonomy. Depending on which taxonomy one employs, the entity in our area may be classified as Hedera helix L. var. hibernica G. Kirchn. or Hedera hibernica (G. Kirchn.) Bean.
