It is a much-branched thorny shrub or occasionally a small tree, generally found on rocky limestone slopes at low and moderate altitude, flowering in the early spring. It is related to the cultivated almond (P. dulcis), which is occasionally naturalized in Greece. The latter is an unarmed small tree with broader leaves and larger fruits.A
