Grown by my family for more than 100 yrs. I haven’t used the wood itself but intend to try it as I am cutting several dawn. The trunks of a few are appx 2 inches but with the thorns it is a bugger bear to get to. I have to use a pole saw to cut them. I have, though, used the fruit to make marmalade and a lemonade like drink. I dried some of the rind and powdered it, sister made a an acceptable "bitters" with it mixed with vodka. Anyone else familiar with this shrub? Here is a link about it. It’s about 15 ft tall.
