Arum palaestinum

A tuberous Levantine arum, often called black calla or Solomon's lily, that grows and flowers through the cool, wet Mediterranean winter and spring, then dies back to the tuber for a hot, completely dry summer. Treat it as a winter-growing geophyte: water from autumn to late spring, keep it dry and warm when dormant.

Where it grows wild

Terrestrial geophyte of Mediterranean scrub, field margins, rocky hillsides and olive groves in the southern Levant, often in partial shade of shrubs and walls.

Few records carry an elevation; it grows mainly in the lowlands and hills, roughly from near sea level to the lower mountains.
