Red Spider Lily: Flowers With No Leaves

Temperature: Red spider lilies are hardy through USDA hardiness zones 7 to 10, though many growers find they also fare well in zone 6. They enjoy warm weather and will not survive climates that experience freezing conditions through the winter. If you are growing red spider lilies in the lower end of the hardiness zones, it is advisable to bury the bulb slightly deeper than usual when planting, as this will offer some protection against low temperatures. In cooler climates, this plant will also need protection over winter, with deep layers of mulch.
