Gardeners' Notes:

Everyone I've shared these beans with agree that they're the best-tasting snap bean they've ever had. Long (up to 7"), thin, tender, stringless, slightly flattened pod with a smooth skin, and nice at nearly any stage of growth. They're fantastic off the vine, lovely cooked, and prolific.

I just learned of this variety this year. I bought about 5 pounds of seeds from the local co-op. The germination rate has been 100% and the plants came up early.

These beans are a canner's dream! THERE ARE NO STRINGS!!

You simply pick them, cut off the ends, cut them into pieces and can them up! They are beautiful! A friend shared some she had canned last year and they taste great! I will probably only plant McCaslan beans from here on out!
