Harvest Tips
For cut flowers, harvest in early morning when buds are just beginning to open; cut stems at an angle about 12-15 inches from ground. Place immediately in cool water with flower food. Stems will continue opening indoors over several days. Remove lower leaves to prevent bacterial growth in water. Change water every 2-3 days for longevity (7-14 days).
Fun Facts
- 🌱 Regale lilies were introduced to the Western world from western China in the 1903 expedition by E.H. Wilson, who discovered them in the valleys of central China and found thousands growing wild along a narrow mountain path.
- 🌱 The fragrance of Regale lilies intensifies in the evening and at night, releasing a sweet, intoxicating perfume that can fill an entire garden or room; this is an evolutionary adaptation to attract night-flying pollinators.
- 🌱 Regale lilies can reliably produce 5-10 large trumpet flowers per stem, and a single bulb can produce multiple stems over its lifetime, making them excellent value for gardeners seeking substantial floral displays.
