Would you believe Sears/McConnell catalogue in 1999! I've not seen them since at that price in any catalogue. The best $12.99 I ever spent! I am hoping to air layer a cutting from it and start another.
It is pretty short because we are USDA Z4. It would grow to 6-7 feet in NJ. It is about 4 feet tall. The woody part is 3 feet and it sends out 12" stalks for the flowers.
