Imperial Epineuse came from Clairac, the great prune district of France. It was brought to the United States by Felix Gillett of Nevada City. This sweet French prune plum is used at the English National Fruit Trials as a standard to judge prune flavor. The fruit is medium to large, red to purple with a meaty yellow flesh. The tree is an attractive upright grower. The very sweet, freestone fruit ripens in late August. This prune can be dried without the lye dip required for other varieties. It is very good for fresh eating. The tree requires a pollinizer.
