Arum concinnatum occurs in a variety of habitats including ditches, wet areas and Olea europaea groves from sea level to 350 meters of altitude.

[1] The species occurs from the southern tip of the Peloponnese to south-western Turkey, as well as most eastern Mediterranean islands.

[2] The species is related to Arum italicum,[2][3] with which it shares similar horizontally-oriented rhizomatous tubers and hexaploid chromosome counts (2n = 84).

[1] A. concinnatum is often incorrectly called Arum byzantinum in horticulture.

However, the true A. byzantinum is a smaller diploid species from NW Turkey with small, purple spadix appendices.
