Killarney Raspberry is extremely robust, with some of the best cold and disease resistance available. This could be due, in part, to it being bred in Manitoba.
It is also known for its good flavor and for being firmer than other varieties, which lends to its use in processing like pies, jams, and jellies or for U-Picks.
The Killarney Raspberry is a fast-growing floricane. This means that raspberries will not grow on canes the year they first grow. The mature canes they do grow on, however, produce more berries than primocane varieties.
