The verbiage needs correcting. These do not flower for 5 months, unless there are several different types of lilies in this collection.
What does it mean? Grow 10" then says the height is over 30 inches?! Very very confusing.
10 inch lilies would be pretty sad.
I imagine they mean 10 inches apart and 2-3 feet tall which is a typical Asiatic lily.
But can you plant these now? Spring planting.
ThunderThighs wanna weigh in?
