It still took quite some time to see any growth. Two weeks later, the first bit of green appeared. Mashua cotyledons remain below ground, so it takes the plant a while to form a true stem and leaves. By the time a mashua seeding breaks the surface, it has probably been growing for 2 or 3 weeks.
This mashua, a Ken Aslet x Orange cross, is the farthest along. It looks happy enough. I have high hopes for mashua breeding. At minimum, I would like to see a mashua with the size and color of Orange, but the early flowering and tuber formation of Ken Aslet. Even that would be just an intermediate step, because my mashua breeding project has one simple, overarching goal: improved flavor.
