Summer Grand nectarine

I just had a “summer grand” nectarine from Masumoto farms, in a local grocery store. It was “ugly” (meaning not bright red). I was surprised. I decided anything ugly in a grocery store is worth looking into why they sell it. I told my son we had a good chance of getting some great flavor.

It was phenomenal. I can’t find much information on it. I assume it is just an earlier version of LeGrand, especially since the stone was massive, like LeGrand. It was yellow fleshed, red blush on the skin but not enough red to hide the mostly yellow appearance. It was freestone.

Does anyone grow this?

I don’t grow it, but their website confirms your suspicion, it is a “cousin” of LeGrand.
