Tulips ("Tulipa") also have a long cultural tradition, particularly in the Islamic world. The Persian word for tulips, "lâleh" (), was borrowed into Turkish and Arabic as "lale". In Arabic letters, "lale" is written with the same letters as "Allah", and is used to denote God symbolically. Tulips became widely used in decorative motifs on tiles, fabrics, and ceramics in Islamic art and the Ottoman Empire in particular, and were revered in poetry, such as that of Omar Khayam in the twelfth century.
