"I bought this Cassia [Senna] last year in a 1 gal. size pot. It was about 3 feet tall when I bought it. It grew to about 5 feet tall and wide over the summer. It froze back to the ground this winter. It\\\'s now about 10 feet tall and 8 feet wide. The largest trunks are maybe 3 inches in diameter. It has lots of yellow flowers on it. A very nice specimen tree and also a great butterfly larval food--if you can keep the ants that are on it from eating all the eggs and cats!"
