The Black Bullace is the common "wild" bullace of woods in England, recognisable by its small, round black or dark purple fruit. [9] It is sometimes classified as insititia var. nigra. [10] It can be quite astringent until very ripe, or subject to a slight frost; a larger variety known as the "New Black Bullace" was later developed from it.

A "stone" fruit (i.e., with a plum-type stone, such as plum, cherry, peach, apricot, almond) should be all right, and vice versa ...
