A small, early blooming crocus, it easily naturalises, and is marked by a brilliant orange which is mostly confined to the stamens and style, fading through the bottom third of the tepal. It grows wild generally in the Balkans: Greece, especially in the island of Crete, Bulgaria, Albania and North Macedonia. There are four subtypes: sieberi, atticus, nivalis and sublimis. Its cultivars are used as ornamental plants. Height:.

Subspecies

There are four subspecies of C. sieberi.
  • Crocus sieberi subsp. sieberi - Native to Crete: flowering in April. The white flowers with yellow throats stand up to 8 cm, the outer surfaces of the flowers are marked with varying degrees of purple. The branched styles are deep orange or yellow.
  • Crocus sieberi subsp. atticus - Native to the Attica region of Greece, it has lilac-blue or violet flowers with yellow throats. The corm tunics are more coarsely netted than the other subspecies. It is found growing in stony areas in the mountains and in woods and scrub areas usually above 1000 meters, with flowering occurring from March to June.
  • Crocus sieberi subsp. sublimis - Native to the Peloponnese, southern Albania, North Macedonia, and also found in southern Bulgaria, has pale lilac flowers with pale yellow throats.
  • Crocus sieberi subsp. nivalis - Native to the Peloponnese with lilac-blue flowers that have yellow throats.

    Uses

Crocus sieberi is cultivated in gardens as an ornamental plant for its flowers. It has also been used as food; in Greece the corms are eaten raw - with the flavor said to resemble hazelnuts. In Turkey, the leaves are eaten as greens.
