Gallo, that is really strange. I tasted some raw leaves offered to me at Sun Valley Growers, was over there getting a replacement tree for one that didn't take. I thought they were okay and had kind of a spicy after taste, it didn't linger. Maybe it is the soil you are growing them in that is making them taste odd? I am surprised your chickens didn't go for them right off. We tried giving ours some prunings from Texas Ranger that had full beautiful purple-red blooms attached. I tried to tell Victor to wait until after the bloom to prune, but he was intent on cutting the branches that were growing into the driveway RIGHT NOW, so I said give them to the chickens. He said they totally freaked out! The next day, those flowers on the branches were still there, untouched.
That might not be so strange. Texas Ranger is basically purple sage. While I like sage fresh or dried, you can't use it when canning because it will turn bitter and basically ruin anything that you preserve with sage as an ingredient. Maybe the chooks are trying to tell us something?
I was thinking the same thing.. What if it is a hybrid?? Is that possible?

My DH got 3 seeds from a friend from work, that got them from another country..
