90 days. [Grown in Pennsylvania for many years, "Lanco" is thought to stand for Lancaster County. May have originally been imported from Asia in the early 1900s.] Large green seeds, mild nutty sweet flavor. Harvest beans when the tops of the bean plants start to loose their deep green color, but before the leaves start to turn yellow on top. (There will always be a few yellow leaves at the very bottom of the plants, that's natural.) Do not wait until the beans fill out all the way to the end of the pods, this variety will not do that. Hardy plants may grow 3-4' tall if seeded early. Early group V maturity.
