So I posted a question on the California Rare Fruit Growers forum. It seems that the quince is Pseudocydonia sinensis, also known as Chinese Quince, Karin, Mugua, Mogwa.
I checked the PlantList to see what is currently the accepted name. "Chaenomeles sinensis (Dum.Cours.) Koehne is an accepted name...". So I googled both.
The bark is quite lovely. Why don't more people plant this just for the peely bark?
Where to buy it? Annie's has it on their "wishlist". J.L. Hudson Seeds has seeds.
Apparently there are some at Burbank's experimental farm.
We visited the farm in October of 2014. I checked my photos and found these pictures. I only have a couple photos from this trip. How odd. I'm rarely that reserved in picture taking. Should have had at least 100.
Are these the Pseudocydonia sinensis?
2017 Update: Yes! That's what they were. I found them at another park. There were some still scattered around the park, but no longer on the tree. But I was disappointed with their perfume. They did make a really great jelly, but not really much different than the "regular" quince. However, this looks like it would be worthwhile landscape plant -
- "Chinese Quince", Louis the Plant Geek
- "Cydonia oblonga: The Unappreciated Quince", Page 8 has a sidebar on "The Chinese Quince: Pseudocydonia sinensis". Luther Burbank worked with this quince. Confirms that Pseudocydonia has been around the Quince block, so to speak, having been named both Chaenomeles and Cydonia at times.
- Japanese website with good pictures
- Luther Burbank catalog 1915-1916. Check page 20 for Cydonia. Perhaps this is it? "Red flowers appearing before the leaves".
