Tuberoses (Polianthes tuberosa) are famous for their thick, delicious, intoxicating fragrance from spikes of ivory flowers. This is the single form. It is hardy to zone 7 with protection. Where not hardy, grow in a pot and store in a frost-free location in winter.

The heavenly fragrance of tuberoses is as big a pleasure in August as ice cream. Their simple white flowers are clustered on 3-4 foot stalks above short, daylily-like foliage. Most gardeners grow them in pots (always best in the North) or dig and store in fall (we'll send easy directions), but they're perennial in zones 8-11. We love them so much we named them our Spring 2004 Heirloom Bulb of the Year. Our big, fat, sure-to-bloom bulbs come from an Illinois family farm where they've been grown since the 1930s.
