These are a variety called Pink Reliance. Last year, I ordered a stem, we picked a spot on the eastern side of the property, laid it in, ran a rudimentary trellis, and then figured it probably would die either because of the soil or during one of our infrequent freezes over the winter.
It didn’t. After the frosts ended, we walked out one morning and noticed all sorts of green leaves coming back on the bare stem. Soon after, tiny clusters of grapes appeared, and they’re now moving in to about half an inch in diameter. This after we didn’t do much of anything to protect it after it was planted.
The next project is to build a proper trellis, since it seems intent on being a healthy plant after all. We picked up a couple of 4x4x8 end posts and some galvanized wire for what I hope will be many years of production.
