Plum 'Precoce de Tours', mid July. Also known as Damas de Tours; Noire Hâtive; Prune de Gaillon; Violette de Tours. "Fruit, below medium size; oval, sometimes inclining to obovate, and marked with a shallow indistinct suture. Skin, deep purple or black, thickly covered with blue bloom. Stalk, half an inch long, slender, inserted in a very slight depression. Flesh, dull yellow, rather juicy and sweet, with a rich flavour when highly ripened, and adhering closely to the stone.
An excellent dessert plum, which, when shrivelled, is quite a sweetmeat; also well adapted for culinary use; ripe in the end of July and beginning of August. The tree is vigorous, hardy, and an abundant bearer. Shoots, downy." (The Fruit Manual: Containing The Descriptions And Synonyms Of The Fruits And Fruit Trees Of Great Britain by Robert Hogg, 1884)
