Iris, how could you tell that's H. helix and not another weakly
/sporadically lobed species e.g. H. algeriensis Hibberd?

Hedera helix is the species most likely to be grown as an outdoor ground
cover
in the temperate US. Hedera algeriensis & H. canariensis are not that
hardy.
Also, it looks more like the typical outdoor H. helix. Not that it
matters. The
instructions for growing it indoors are essentially the same.

Thanks. The same would be true here, but H. colchica is also popular as
ground cover. H. algeriensis is grown indoors or on patios but is only
occasionally established in the wild for any length of time, and then mostly
by mild coasts.

What's the difference between H. algeriensis and H. canariensis, by the way?
