Biarum carduchorum

A small tuberous aroid of the Kurdish uplands of south-east Türkiye, northern Iraq and western Iran, growing on open stony slopes around 1000-1100 m. Like the rest of the genus it is a summer-dormant geophyte: leaves and flowers come with the cool, wet half of the year and the tuber sits bone dry through a very hot summer. Grow it as a cold-hardy bulb in a deep pot of gritty mix, kept bright and cool in winter and dry and warm in summer.

Where it grows wild

Recorded from upland sites in a continental climate with cold, wet winters and long, hot, rainless summers. Published detail on its exact microhabitat is thin; Biarum of this region typically grow in open stony ground, rocky steppe and among dwarf scrub on limestone or basalt.

The three records with elevations fall at 1000-1100 m; other sites in the region may be higher.
