I didn't purchase these beans from Mary's but I did grow them last season. They are insanely delicious fried up in butter or oil, best bean I have had. The flat, smooth bean makes for such a nice texture. I will be ordering them here this year because I the original source no longer sells this variety. It was easy to grow (pretty much all beans are) and prolific. I just kept coming back and harvesting and it seemed like everyday it had new beans. They were even slightly cold hardy once the fall came. I planted mid august and they still had time to produce a bunch. The was a first cold nap and they got sad for one day but then bounced right back and kept producing. Definitely a gourmet bean.
