Taxonomy The Latin specific epithet fosteriana refers to Michael Foster (a known British Iris expert). 'Tulipa fosteriana was first published and described by Walter Irving, a British botanist (1867-1934), in Gard. Chron. III, Vol.39 on page 322 in 1906. In 2013, the phylogenetic relationships in the genus using DNA sequences was used to determine the taxonomy and classifications. As result T. fosteriana was placed in 'Tulipa subgenus Tulipa' (along with Tulipa agenensis Redouté, Tulipa hungarica Borbás and Tulipa greigii Regel ) with the characteristics of; bulb tunics densely lined inside with rippled or silky hairs or (nearly) glabrous. Stamens without hairs orboss. Stigmas sessile. Distribution T. fosteriana is native to temperate regions of Central Asia. It can be found in Afghanistan and Tajikistan. Habitat It is found in the wild on rocky scrub-covered hillsides, or on stony slopes at an altitude of above sea level. Cultivation Resistant to tulip breaking virus, it has been crossed into garden tulips (Tulipa × gesneriana). They naturalize easily and can come back year after year in the garden. They are well suited to mixed borders and can also be used in bedding displays. They can grow in any garden soil but prefer sites in full sun. They also can be propagated vegetatively and also by seed. It can grow in USDA Hardiness Zones: 3 to 8. It is a well-known species, which has been the originator to many cultivars. The various cultivars can differ from one another in height, but all have solitary, bowl shaped flowers that are 5in wide (12cm), with a slender and sometimes striped leaves. Its cultivar 'Juan' has gained the Royal Horticultural Society's Award of Garden Merit. It has red-orange flowers with yellow centres and variegated leaves. Tulip
