Growing Fragrant Tuberose Plants
Fragrant, showy flowers in late summer lead many to plant tuberose plants. When planting tuberose plants, keep in mind that timing and location are key for success with these flowering plants, due to their lack of hardiness. Tuberose plants should be planted in the springtime after the last frost, as they are not cold-resistant. They require full sun but can react negatively to extremely warm temperatures. The bulbs can be stored indoors in autumn and reused the following spring. Plant the bulbs approximately 8-10 inches (20-25 cm) apart, and make sure that each bulb has about 2 inches (5 cm) of soil over it. Choose a location with direct sun. For areas that reach summer highs of 95 degrees F (35 degrees C) or higher, plant tuberose bulbs where they will receive partial shade during the hottest part of the day. Extreme heat can shrivel tuberose flowers or prevent buds from opening.
New growth might not emerge from a tuberose bulb until up to four weeks have passed. Tuberose plants typically bloom in midsummer and could continue producing flowers until temperatures drop. All tuberose bulbs should receive water on a weekly basis. They will perform best if they are planted in well-draining or sandy soil. Provide fertilizer during the warm months to encourage continued growth and blooming.
