A couple of years ago Hubby found 1 rouge plant in a row of Cherry Romas. All the other plants were about dead but this plant was still nice and healthy. The fruit were different too. Instead of the Cherry Roma grape shape, they were round like a regular cherry. Not red either but kind of red-pink. We don't know if it's just a plant mix-up or a bee cross or ?? We grew it out again the following year and it again seemed more disease resistant than the other varieties around it.
