Looking for a source for Daubenton Kale
Does anyone know of a US source for Daubenton Kale (Brassica oleracea ramosa) or at least a source that will ship to the US? It is also known as Chou Daubenton and Chou d'Aubenton. my understanding is that it is available commercially in France but not anywhere in the US. It's a perennial kale and as my two "pet projects" in the garden are edible perennials and kales, I'm dying to get my hands on this! Any help is appreciated.
