Polianthes tuberosa
Tuberose
Polianthes are deciduous tuberous perennials, native with lance-shaped leaves, and upright stems bearing clusters or spires of tubular or funnel-shaped waxy flowers that are often very fragrant. Polianthes tuberosa needs a minimum temperature of 15C (59F) so in cooler climes is suitable for growing in a heated greenhouse or conservatory. It can also be grown outdoors in containers or sheltered sunny borders, as long as it is lifted and placed in a frost-free environment over Winter.

Polianthes tuberosa
Polianthes are deciduous tuberous perennials, native with lance-shaped leaves, and upright stems bearing clusters or spires of tubular or funnel-shaped waxy flowers that are often very fragrant. Polianthes tuberosa needs a minimum temperature of 15C (59F) so in cooler climes is suitable for growing in a heated greenhouse or conservatory. It can also be grown outdoors in containers or sheltered sunny borders, as long as it is lifted and placed in a frost-free environment over Winter.
Flowering
From Early Summer TO Late Summer
The usually fragrant waxy flowers appear from early Summer and all through Summer
Planting
From Early Spring TO Mid Spring
Plant the bulbs 10 cms. deep in in free-draining loam-based compost, and keep in a minimum temperature of 15C (59F). Water when planted, and water sufficiently thereafter to keep the soil moist, but not waterlogged.
Propagating by offsets
From Mid Autumn TO Late Autumn
Offsets are the baby plants that form at the base of some plants, and they are an easy way to propagate a plant. When the offsets have grown large enough to handle - and, hopefully, have some roots of their own,- gently break them away from the mother plant. Plant the offsets in a container and keep the plant barely moist (but not wet) until the plant is establishes, and can be planted out.
