An excellent smooth seeded pea for winter growing. I plant them about Thanksgiving for harvest in April-May. Of course they are not as sweet as wrinkle seed peas but very prolific. Flavor is comparable to Early Alaska, but I prefer Willet Wonder for its shorter more manageable plant.
I grow a pea called Merveille de Kelvedon which I got in France, but I think it's really an English pea called Kelvedon Wonder. I tried ordering some of those and they didn't come up at all, so I still have to save seed from each year's crop of my original Merveille de Kelvedon for the next year. I really like them; they have a great flavor and they freeze well.
