My bulbs are two years old now and the stalks this year were nearly seven feet. Each stalk had five or more flowers. They did not require staking until a heavy rain loosened the soil. A very nice cultivar if you want height. I wish they would let me post a picture.
I love orienpets! They are beautiful, hardy, lilies that attract a lot of attention. It takes a couple seasons for them to reach full height, but it is worth the wait.
