Single Petal Rajnigandha

Tuberose (Polianthes tuberosa) is a perennial of the asparagus family (Asparagaceae), native to Mexico. It grows from tuberous roots, producing bright green leaves clustered at the base with smaller clasping leaves along the stem.

The plant develops tall spikes up to 3 ft, bearing pure white, waxy tubular flowers. Each bloom flares into six segments (tepals) and releases a rich fragrance at night, making tuberose highly valued for its perfume and ornamental beauty.

Mexican Tuberose Single Petal bulbs yield elegant white flowers with a single row of petals, celebrated for their intense fragrance—often stronger than double-petaled types. Widely used in garland making, they bloom July–October in plains and August–November in hill regions. Planting from February–April (plains) or March–May (hills) ensures vigorous bulbs that return each season with their signature nocturnal fragrance and striking blooms.

Planting & Care

Tuberose thrives best in sunny locations and requires full sunlight to bloom. Well-drained loamy soil with a pH of 6.5–7.5 is ideal for healthy growth.

Plant bulbs in the fall, 3–4 inches deep and 2 inches apart, in any well-drained soil for good results. Flowers typically appear in mid to late summer, about 90–120 days after planting.

Tuberose needs a rest period during winter to ensure strong summer blooms. The plants are heavy feeders and benefit from applications of 8-8-8 fertilizer during active growth.

Bone meal at planting and after blooming further supports healthy bulbs. Reduce watering once foliage begins to die back to prepare the plant for dormancy.

Landscape Use

Tuberoses are excellent in the garden or in pots. Their tall stems (2-3 ft.) and rather sparse, grass-like foliage make them ideal for inter-planting.
