Crocus pallasii (Iridaceae) is a cormous plant native to a wide area from the Balkans to Israel via Turkey, growing in calcareous grassland and open habitats. In late autumn it bears goblet-shaped flowers, silvery lilac with a deep purple eye, bright yellow anthers and a style divided into three short red branches. It belongs to the same botanical group as cultivated saffron. Grow in full sun, in well-drained calcareous soil that stays dry in summer; hardy in most temperate regions.
