Biarum angustatum

A small, summer-dormant tuberous aroid from Syria, Lebanon and the Levant. The few wild records sit in the hot, low Jordan Valley near Jericho. It is a warm-winter Biarum: grow it through a mild, bright winter and keep it bone dry and hot in summer.

Where it grows wild

The records come from the floor and lower slopes of the Jordan Valley. Like other Biarum, it probably grows in stony, often calcareous soil in open steppe.

Records lie near and below sea level in the Jordan Valley, to about -100 m. No elevations are recorded on the specimens.
