Poncirus trifoliata

This spiny shrub/tree can grow to 20 feet and is native to Korea and N China. It can be used as hedging material and does not seem to mind being cut back. It is perfectly hardy. The spines are 1-2 inches long and very sharp. The fruits are like small oranges about 1½ inches across. See Poncirus trifoliata (fruit).Very bitter, but can be used in conserves and drinks (Rutaceae family).
