Cultivars
'Mexican Single'
Polianthes
Polianthes tuberosa 'Mexican Single' is a highly fragrant perennial prized for its waxy white, funnel-shaped blooms with six spreading petals. The flowers appear on tall spikes, reaching 3 to 4 feet in height, and are especially fragrant at night, making them ideal for moon gardens. Blooming in mid to late summer, this variety thrives in full sun with well-drained soil and requires consistent moisture during the growing season. Hardy in USDA zones 7 to 10, it performs best when lifted annually, even in warmer climates, to encourage strong re-blooming.

Polianthes tuberosa 'The Pearl' is a double-flowered tuberose known for its highly fragrant, creamy-white blooms. The flowers appear on tall spikes, reaching up to 4 feet, and open in succession, ensuring a long-lasting display. Blooming in mid to late summer, this variety thrives in full sun with well-drained soil and requires consistent moisture during the growing season. Hardy in USDA zones 7 to 10, it performs best when lifted annually in colder climates to encourage strong re-blooming. The sweet, intoxicating fragrance makes it a favorite for gardens and cut flower arrangements.
