Narrative
Excellent quality, medium sized dessert pear. Reportedly came out of the Tennessee breeding program with Ayres. Apparently there is more than one cultvar propagated as Tenn in the South. This is the good one. It has a slightly pyriform shape, fairly uniform, and has a nice red blush on one side. About 350 - 400 chill hours (commonly sets two crops in Houston). Tree is very large and spreading on calleryana.
