Sternbergia is a genus of the Amaryllidaceae family, found along the Mediterranean basin and the Middle East, often growing in rocky places. Although they look a bit like Crocus, they are more closely related to Narcissus. Most of them are yellow and bloom in the fall, but there are a couple of spring flowering species and one that is white. They are winter growing species and summer dormant. Many of the fall blooming species bloom after the first rains and before their leaves are produced.
Sternbergia candida is a rare species of western Turkey, recently described and endangered in the wild, primarily because of collection for the Dutch bulb market along with the more common S. lutea. It flowers in late winter to early spring (here, in January in a bulb frame in Oregon, USA). The first photos below from Jane McGary illustrated a plant that was grown from seed purchased from Jim and Jenny Archibald and took 6 years from sowing to flowering. This is the only white-flowered Sternbergia. The final photo is from John Lonsdale.
Sternbergia clusiana is found in Jordan, Israel, Turkey to Iran.- Stereo pair photos, in an England garden submitted by Brian Whyer. Taken November 2003. The first is a true left/right stereo pair, the second right/left, of the same clump. You should be able to see 1, or maybe both pairs of them in stereo, by crossing your eyes until the 2 images overlap, or a third image appears in the centre, and with practice they will/may suddenly appear in stereo. Note although this is off eight large bulbs, the flowers emerge, before the leaves, through one relatively small hole, presumably taking the route of least resistance through the stony clay chalk soil.
Sternbergia clusiana photographed in the wild in southwestern Turkey by Jane McGary, in early November 2006. Plants were growing on a steep bank and in rocky soil in scrub.
Foliage of Sternbergia clusiana, a plant received by Jane McGary in the mid-1990s from Panayoti Kelaidis, who had Sternbergia candida in his garden and thought this was it; the leaves are similar). It finally flowered in fall 2003, grown in an unheated bulb frame, dry in summer. Panayoti's bulbs were purchased as S. lutea at a garden center and were undoubtedly wild-dug.
Sternbergia colchiciflora is a diminutive species occuring in Italy, but very difficult to locate. The plant in leaf and fruit resembles a miniature Sternbergia clusiana with its spirally leaves and the fruit at ground level. Leaves are finely ciliate indeed.

Sternbergia fischeriana is a yellow flowering spring blooming species that occurs in stony places in Turkey, Iran, and Iraq. It needs deep-planting and a warm dry summer rest to flower well. Photos by John Lonsdale
Sternbergia greuteriana This is one of several smaller species. The photo includes a flower of S. lutea for comparison. S. greuteriana is easy to grow in an unheated bulb frame, increasing modestly. These plants were grown from purchased seed of garden origin. Photos by Jane McGary and John Lonsdale.
Sternbergia lutea is the most often grown of the fall blooming species, found in Europe and Asia. In Italy it occurs usually in stony soils, in open areas (first three photos by Angelo Porcelli). It is still rather common in rural areas, along country roads. The fourth photo was taken in the Mani Peninsula, southern Greece, in late October, by Jane McGary.
Occasionally, multipetal forms can occur, as in Zephyranthes. The first photo taken in habitat by Angelo Porcelli in Apulia- southeastern Italy illustrates this. The next two by John Lonsdale show the typical forms.
Sternbergia sicula, photos by Mark Wilcox. Both photos were taken at the top of the mountain above Acrocorinth in the Peloponnese region of Greece. The first picture shows a plant that has somehow grown inside a small opening in solid rock. Flowers are shown in bud, bloom, and withered states. The second photo was taken a few feet away, showing another blooming plant with leaves, more typically sited in soil. They had a southern exposure.

Photo by Jane McGary in the Mani Peninsula, Greece, late October. Plants considered to be S. sicula rather than S. lutea are said to grow in more sharply drained habitats than S. lutea, to have narrower leaves, and to be slightly lighter in flower color; however, the distinction between the two entities, both of which grow in this area, is not entirely clear-cut, and some botanists combine them. The Kew monocot checklist lists the name Sternbergia lutea ssp. sicula as the accepted name.
