Kalle Pear on OHxF 87 (Spring 2024)


A beautiful, red-skinned early pear. Also known as Red Clapp's, Red Kalle, Starkrimson™.

Kalle is a red sport of Clapp Favorite and behaves much like its parent. The tree is large, upright-spreading, very productive, and it is a reliable pollenizer with no incompatibility issues. It is resistant to rust, susceptible to fireblight, and very susceptible to scab. It performs well in a wide range of growing conditions, particularly the Pacific Northwest.

The fruit is a dramatic, deep red pear that ripens about ten days before Bartlett. It is an attractive landscape feature and would make a stunning espalier. The fruit quality at harvest is outstanding, with sweet, melting flesh. Unfortunately Kalle does not ship or store well.

This sport was discovered by Adrian G. Kalle of South Haven Michigan. It was introduced by Stark Bros. Nursery in 1970 under the trademarked name Starkrimson.
