Tuberose (Poliyantha tuberosa)

Tuberose is a very popular commercially grown loose/cut flower. It is a half hardy, herbaceous perennial with fibrous roots, 60 to 120 cm high, having a bulb like tuberous rootstock and fleshy leaves linear, grass like foliage. The foliage is narrow at the base and wider at the top and is arranged in a rosette at the base.

The flower is perhaps best known for the extremely intense fragrance emitted by its waxy white funnel-shaped flowers that appear in elongated spikes rising to 30” tall in late summer. The scented flowers are hermaphrodite (have both male and female organs).

The tuber is bulb-shaped and the plant is commonly grouped among the `Bulbs’. The leaves are 70-80 cm long, narrow, linear and bright green in colour. The flowering stalk which emerges from the centre of the cluster of leaves is about 80-120 cm long bearing successively smaller long pointed clasping leaves, uppermost ones are much reduced and bract-like. The flower buds are tubular. Flowers are 5-6 cm long, borne in pairs in an open spike pure wavy white, highly fragrant, tube 2.5 to 3.0 cm long, slightly bent near the base, expanding widely where it meets the oblong obtuse segments.
