Growing and Training

Stark Crimson is suited to most climates, however it is susceptible to fireblight.


History

Stark Crimson is a good example of a "sport", a natural genetic mutation. The original Clapp's Favorite was raised by Thaddeus Clapp of Dorchester, Massachusetts in the 1850s, possibly a cross between Bartlett and Flemish Beauty. It is essentially a green pear but with a tendency to show some red flush. In the 1930s Adrian Kalle, a grower in Van Buren County, Michigan, noticed that one of the branches of a Clapp's Favorite tree growing in his orchard had pears that were a solid dark red color - quite different from the normal red-flushed green pears on the other branches. This new form was patented in 1952 and taken on by Stark Brothers nursery under the name Starkrimson, but today it is more widely known as Kalle or Red Clapp's Favorite.
