Arum gratum

A tuberous Arum from Lebanon and western Syria, noted for its sweet-scented spathe. Like most eastern Mediterranean arums it grows through the cool, wet winter and spring, then goes completely dormant through the hot dry summer.

Where it grows wild

Little is recorded for this species; by analogy with related Levantine arums it grows on rocky hillsides, in scrub and at woodland edges on limestone. This is generalised from the genus.

No wild records carry an elevation; related species in Lebanon grow from the foothills into the mountains.
