We enjoy watching your show.
These two oriental hybrid lilies are just short of 9' high, with flower heads 3'. The bulbs are either a "Conca D’OR" or "Cherbourg". I bought one bulb at a store or plant show, and now have two bulbs with stems nearly 1 1/2" thick. I have done nothing special, such as fertilizer, to cause this. They are growing in mostly shaded area.
Please let me know if you know why a common oriental hybrid lily can grow so high.
