Tuberose (Polianthes tuberosa) is a perennial, ornamental, flowering house plant. It grows in elongated spikes up to 18 inches long that produce clusters of fragrant waxy white blossoms that bloom from the base towards the top of the spike. It has long, bright green leaves clustered at the base of the plant and smaller, clasping leaves along the stem. The unopened buds are pinkish but the blossoms are pure white, tuberose thrives in sunny spots and bloom in late summer. The blossoms will appear about 90 to 120 days after planting, usually, late summer or early autumn, removal of the blooms for house display will not harm the plant. It has three major varieties common, single flower, double blossom and semi-double blossom available for summer season and winter season separately. Locate your plants near patios, walks, decks or other living space so that the fragrant blooms might be enjoyed to the fullest.
