Is Tuberose a Sunny or Shady Plant?

The tuberose (Polianthes tuberosa) is an herbaceous bulbous plant that produces fragrant, white, tubular flowers. Its pleasing smell and long life as a cut flower make it a southern gardening favorite. Like most bulbs, the tuberose is a sunny plant, thriving in full sun locations.

  1. Sunlight Requirements

    • Tuberoses need full sun for proper growth. Too much shade will result in poor vegetative form and limited flowering.

    Other Growing Requirements

    • Tuberoses grow in USDA hardiness zones 8 and 9. Plant tuberoses in productive, well-drained soil. If well-drained soil is not present, consider installing a raised flower bed. Keep soil moderately moist. Fertilize once or twice during the growing season with bulb fertilizer.

    Landscape Value

    • Tuberoses produce the highest visual effect when massed in a flower bed or border. To create a massed display, plant the tuberous bulbs 4 to 8 inches apart under 2 inches of soil during the months of January through March. Given proper growing conditions, the plants will multiply rapidly.
