Marek, the heights I reported are not unusual here in North America. These lilies seem to grow exceptionally well just about wherever lilies are grown in USDA zones 8-5. The 'Leslie Woodriff' I described grows outside my bedroom window. The floor is about two feet above ground level, so when the lily is in bloom the entire inflorescence fills the view. In the garden a nine-foot lily does not look as tall as you might think it would. Take a look here at the home page of the Potomac Lily Society; there you can see two images of lilies in a garden setting. Most are 'Silk Road' with one 'Dunyazade' in the background; all of these stems are over six feet high. That's my bedroom window in the background. http://www.potomaclilysociety.org/ Jim McKenney
