Kalle Pear Scionwood (Spring 2025)


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.

Clean vs. Regular

Our clean scion is harvested from trees grown on G.16, which is extremely sensitive to viruses. These trees would not have survived if the scion contained viruses. Our clean wood has not been lab tested. Regular = may contain one of the common latent viruses; this is not usually a problem and can be used with most rootstocks.
