Arum idaeum

A small tuberous Arum found only in the mountains of Crete, with arrow-shaped leaves and a pale spathe in late spring. It grows through the cool, wet winter and spring and then goes fully dormant in the hot, dry summer, so it is handled like a hardy Mediterranean bulb, not a tropical aroid.

Where it grows wild

Grows on rocky limestone mountain slopes, in stony clearings and among rocks and low shrubs, where the tuber sits in pockets of soil between stones. Specific habitat detail is limited; this follows the measured sites and other montane Mediterranean Arum.

Recorded at about 1,060 to 1,150 m in the few dated records, with a climate site near 1,480 m; it is a plant of the Cretan mountains, not the coast.
