@Baja_Costero I have over a hundred Hostas and a lot of bushes, perennials. I know the names of everyone of them. I agree work your brain like you work your body. Don't use it you will lose it.
I paid money for them and I remember handing over that credit card for them. I do not need a name tag to remember the names. I will forget what I paid but I know it cost money.
