Bean Rocquencourt. Yellow bush French bean named for the farming village of Rocquencourt near Versailles in France. It has been grown commercially since at least the 1930s and it remains popular throughout Europe. It has a smooth, buttery taste and stays crisp when cooked. It is unequaled for fresh eating and cooking, and the black seeds can be used as dried beans. Starts to produce in 55 days or less. Pick when no thicker than a pencil for best taste and productivity. The more you pick, the more it will produce. Compared to Brittle Beurre, Rocquencourt is a bit longer and slimmer and has a much more orange color. 60 gram (2 ounce) pack.
William Woys Weaver, an expert in heirloom vegetables, calls Rocquencourt "the aristocrat of wax beans." You can read more about the history of Rocquencourt on his blog at Mother Earth News.
