The Blackburn cranberry cotoneaster is somewhat more compact and refined than the species but shares the same pinkish white small blooms and abundant red berries in the fall as well as the low spreading habit.

Members of the genus Cotoneaster are characterized by a stiff, dense branching structure, small, glossy leaves of fine texture, and abundant fruit in the form of small pomes, which are generally in shades of red/orange but may also be cream or black and may persist into winter. Generally unfussy about soil pH, cotoneasters are reliable and durable shrubs often used as hedges or groundcovers.

The genus Cotoneaster includes at least 90 species of shrubs native to the temperate regions of Europe and Asia, with a concentration in western China. There are no cotoneasters native to the U.S., though a number of species and their hybrids and cultivars flourish in the northern U.S. and Canada. The Chicago Botanic Garden's collections contain almost 20 species among nearly 30 varieties and more than 2,500 individual plants.
