Boston Picking Cucumber is a very old (first documented in 1877) reliable pickling cucumber that was "improved" sometime in the 1950s giving it resistance to cucumber mosaic virus and cucumber scale. Boston Pickling cucumber has been around for a long time for good reason, it is the standard for homemade pickles. It produces heavy yields of small 6" cucumbers down right perfect for pickling. It is best to harvest boston pickling cucumbers for pickles when they are 2" to 6" long. That way they fit in your jars!! I use these Cucumbers in my salads. I like the firmer less seedy centers.
