Arum lily - Zantedeschia aethiopica

I don't think it's that particular one but certainly same family.

Perhaps Calla lily.

The leaf veins are both far fewer in number and more prominent than in the calla lilies I'm familiar with.

aren't calla lillies from bulbs?
when I planted it...there were no bulbs
but a root system.
leaves are thinner than calla lillies
that I have in another flower bed.

Leaf shape is different also. Once the plants get big enough an inflorescence typical of the family - that is, with a spathe and spadix - is liable to appear. It probably won't be as conspicuous as that of the calla.

Zantedeschia grow from rhizomes ( closer to tubers, not actual bulbs). I second: prominent veins don't fit, together with the leaf shape.

So probably another genus, other Zantedeschia species seem to have different foliage also.

Going dormant would fit with some swampy habitat and draught period.

Did you get it as a garden plant?
