Believe that Hidden Springs Nursery has offered it in the past.
Think I have one that came labeled as something else(maybe a seedling of Richard Fahey's 'Cherry hawthorn'?)...planted among a group of grafted mayhaws, but has not fruited here.
Leaves match photos I've seen.

Found it at Raintree. It also has 2-3 improved cultivars. I'm not sure what rootstocks they use and the hardyness. It is hardy in Zone 6...

I just added one from Burnt Ridge last year. The cultivar is "Da Mian Qui", on quince rootstock. It barely survived mistreatment in a pot last year. This year, it is doing better, after I planted it into a large mound in a wet area.

From when she was young in China, my wife remembers very flavorful candies made from Haw. I doubt it will be palatable fresh- hopefully I'll find out in the next year or two.

I tried them and I didn't like them, so I grafted other types of hawthorns on them that I like better. Hawthorns stay on the tree much later than other fruit (Dec, Jan, Feb, March here) depending on the year. THey have a lot of medicinal benefeits, particularly to your heart and related systems. They are full of antioxidants. I prefer carriere hawthorn and another kind I"ve found growing out here as a street tree. Chinese often add lots of sugar to their hawthorns and fry them. I didn't want to do either of those things.

The improved varieties have larger fruits, not sure if they are any sweeter. The fruits can be 1 1/2" large. The fruits are sour for fresh eating. They can be made into jelly, candy or processed.

If fruits stay that late, then they are nice ornamental small trees. Just like persimmon.

Yes, just found it. They call it Chinese Haw, not Hawthorn.... dumb :-)

I'll see if I want to try it. I figure this is much less common than the jujube....
