This spring i did a test of potato varieties:

1. Red: a variety we’ve grown for years, probably the common “red bliss”, which has been a reliable producer
2. White: seeds of change “German Butterball”
3. Blue: seeds of change “All Blue”

I planted three beds in different areas of the upper garden, with the varieties in equal areas of each bed.  Here are the results in pounds of potato per plant: Red 0.84, White 1.64, Blue 0.33.  The German Butterball was amazing!  In our soil and climate, it’s a clear winner.  We’ll be carefully keeping and replanting that variety.
