I bought this from a lily grower in the mountains of North Carolina between linville and spruce pine off hwy 221. she had it in a pot at the edge of here driveway for sale and when i saw it i jamed on my breaks and had to turn around and get it. It's 48 inches tall, and only a year old so the height isn't that of the regular 36 in asiatic lily but more similar to the orienpet giant hybrids that can get 4- 6 ft. it's a beautiful cream color that radiates and glows in the sun light. also very fragrant as its perfume smell filled my car and gave me a bit of a headache on the ride home. mike
