waxy/mealy/all-purpose potatoes

Mike is partially correct. Only potatoes grown in Idaho can be called Idaho potatoes. So, not all russets are Idaho potatoes. Nearly every state grows potatoes, Idaho produces one third of all production followed by states such as Washington, Colorado, North Dakota, Nevada, Nebraska, Wisconsin, etc. Idaho surpassed Maine in the late fifties as the number one producer. Now, while Idaho grows more Russet Burbanks (62 percent of the 320,000 acres for the 2007-08 crop) than any other state it also grows a brown Ranger variety (15%) and a Russet Norkotah (10%). That leaves 13%. Most of the remainder are red varieties and some yellow flesh. Idaho actually had one grower last year harvest 1 million pounds of fingerlings. Most of these niche varieties are available from Idaho September to March. One of the best links I have found on variety descriptions is at:
