Gene Logsdon has been pushing the idea of grains as a garden crop for some time - a "pancake patch." For a gardener in the pursuit of extreme, high intensity gardening projects, this was immediately appealing - and I say ranks up there with growing bananas in Ohio.
I put his book, Small-Scale Grain Raising, on my library que some months ago, but some local dummy is sitting on his borrowed copy (there's no excuse, it's a very short book). I'll probably just buy a copy when I get some money.
The wind was knocked from my sails this past week however, when my boss pointed out a problem with my plan. He was on a homemade bread tangent when I started asking questions about the logistics of getting usable flour from raw grain. This led him to an anecdote about a local mill that was trying to sell some variety of "local, organic" bread flour. Shortly after it appeared on the shelves, the co-op was inundated with complaints regarding the poor baking quality of the flour.
The fruit quality of grasses, like any plant, is heavily impacted by the environment. Mills routinely test and mix different batches of grain to assure that the final flour product has appropriate levels of gluten, etc. This little local mill, which was only able to buy grain from one farmer its first year, was unable to correct quality imbalances and was forced to sell an inferior product. They hope to recruit additional farms in the new year.
I suppose this isn't a deal breaker - it just means that cereals aren't completely foolproof.
I bet a dwarf wheat variety would make a nice front "yard."
