ABSTRACT
AA Polianthes tuberosa is commercially grown as a cut flower and in some countries, such as France and India, for use in the perfume industry. Few flowers rival the fragrance of the waxy white single- or double-flowered P. tuberosa; neither form is known to exist in the wild. Trueblood12 has published an interesting thesis on P. tuberosa and indeed the entire genus. Interestingly, P. geminiflora Rosa is red in color. A. C. Joshi and J. V. Pantulu have conducted an extensive morphological and cytological study on P. tuberosa. Tuberoses are commonly field-grown during the summer for cut-flower production. L. B. Singh reported that P. tuberosa has been successfully grown in soils of high alkaline-saline content. Flowers are tubular, usually in pairs, 6 cm long, forming a terminal spike some 4 to 6 cm long. The 6-lobed tubes bend down near the base; there are 6 stamens.
