This is a family-run farm dedicated to preserving rare poultry and vegetables. Orders are accepted by post only, and credit cards are not accepted. You will not believe the breadth of Sand Hill’s offerings, many of which are rare. For example, they offer a selection of heirloom beans form Appalachia. Unfortunately, while there are some good thoroughly descriptions in their catalog, others are terse, in the extreme. For example, this is the description for a tomato called Stone: mid, Ind, rather hard fleshed, round in shape, 10 oz. fruits. Pkt. $1.75 OG. Plant descriptions are probably overrated, anyway, partly a literary form that makes perusing seed catalogs such a pleasure. In this case, which is really always the case regardless of the prose, I doubt you can go wrong with any of their selections as long as you live where the summers are hot. Sand Hill Preservation Center is located in Iowa. They are thus able to grow and offer sweet potatoes, a root crop that will not thrive in my Coastal California garden. If you are lucky enough to live where the summers are hot, at the very least, peruse the Sand Hill catalog and order sweet potatoes. This is a family business that can use your support.
