Can you tell us why?
From what i gather the ‘Fragrant’ pears are Chinese cultivars crossed with Euro pears which give them fragrance. Tsu Li in just about every description not only resembles a Euro pear but almost all reviews talk about its smell/fragrance/floral notes.
Your description in this thread along with Scotts mentioning that ‘fragrant’ pears are cellaring pears… also fits.
Im not sure we can have a Fragrant Pear thread or discussion without knowing what makes a Fragrant pear. I would think it would be somewhere along the lines of being a Chinese pear, being crossed with a Euro pear, have fragrance/floral notes/aromas, and need to be stored/cellared…or as they use them to be exported all over the world in cold storage…
Hard to really know as some of these Chinese pears have been cultivated for thousands of years and most of our (US) information and plant material is via Japan. I think many folks have gotten the wrong plant material from the USDA as well. Perhaps the fruit that is imported from China doesnt match what we grow as named varieities here. Thousands of years of cultivation would obviously lead to many variations i would think.
This is a very in depth detail of what was known about Tsu Li/Tzu Li and Ya Li half a century ago.
