Its basal leaves grow in clusters of 6-9 pieces, linear, 40-60 cm long and 1 cm wide, with pointed tips and dark green. The leaves on the flower stem are scattered, gradually smaller in the shape of a bract. The tuberose spikes are terminal, with 2 flowers in each bract, and the bracts are green. Flower is milky-white, fragrant, 3.5-7 cm long; tepal tube is 2.5-4.5 cm long, slightly curved at the base, tepal lobes similar to each other, oblong-lanceolate, 1.2-2 cm long, blunt head. Tuberose has 6 stamens, inserted in the tepal tube, hidden inside.

Tuberose efficacy and role

The ornamental value of tuberose

Tuberose with green leaves, stalks, jasper rosy, scented and clean, with a delicate fragrance, making people forget the summer heat in July and feel refreshed.
Tuberose has a long flower stem and a long flowering period. It is an important material for cut flowers and a beautiful flower for flower beds.

The economic value of tuberose

Tuberose is the raw material for extracting flavor. The main components of tuberose extract are geraniol, nerol, neryl acetate, methyl benzoate, methyl anthranilate, benzyl alcohol, farnesol, eugenol and tuberose ketone, etc. For food, it can give food a unique smell of tuberose.

Tuberose growth habit and growing environment and distribution

Tuberose is native to Mexico and South America and is cultivated more in northern China than in southern China. In 2004, Tianjin was introduced and cultivated. By 2004, some flower farmers in Xinhe, Shucheng and other towns of Shuyang County, Jiangsu Province introduced and tried planting successfully.
Tuberose in its place of origin is evergreen grass. It grows year-round when the temperature is suitable. It blooms in four seasons, but the summer is the most prosperous. When it is cultivated in open field in China, it can only be cultivated in spring because of the severely cold winter in most areas: Buds grow in spring, bloom in summer and autumn, and dormant in winter (forced dormancy). Tuberose self-pollinates, but since the pistil matures later than the stamen, the natural seed setting rate is very low. Tuberose likes a warm, humid, sunny environment, and its growth temperature is 20-30℃. The requirements for soil quality are not strict, and clay loam is suitable. Tuberose is more sensitive to soil moisture and prefers fertile, moist, but water-free soil.

Tuberose cultivation

Tuberose is mostly propagated by dividing bulbs. In late November, the underground stems are dugout after the upper ground withered to remove the shrinking old bulbs. Generally, each cluster can be divided into 5-6 flowering (large) bulbs and 10-25 reproduction (small) After drying the balls, store them in a dry place. The balls are divided in spring, and the big and small balls are planted separately. The big ball of tuberose can bloom in the same year, and the diameter of the big ball for cut flower production should be more than 2.5 cm. The small bulbs can be cultivated for 1-2 years and grow into bulbs with a diameter of more than 2.5 cm before flowering.
