German Stiffneck is an excellent Porcelain garlic popularized by John Spamer, a NY organic grower who is now retired but sold it both locally and mail order for years and developed a loyal following. German Stiffneck is the same as German Extra-Hardy, German White and Northern White grown under different names) and is a large, beautiful and well-formed porcelain garlic. These are all basically the same garlic but grown in different places under different names. Its flavor is very strong and robust and sticks around for a long time.
From a grower's perspective, it is a tall dark green very hardy plant and is a very good survivor, usually grows healthy and appears to be somewhat resistant to many of the diseases that can affect garlic. It originally came from Germany with immigrants a couple of hundred years ago. German Stiffneck grows well in all but the most southerly states, where it grows fairly well in cooler winter/spring years but is marginal in years with early hot summers.
