I am going to get serious with my name tags for my Crotons. I have used the plastic ones found in the garden centers in the past. Problem is that I can only read them for a year or two. I am going to go with aluminum (1"x 3 3/8") with paper core easy to write on with pen or stylus. Any thoughts? What do you use ? I just can not remember all the names as I have over 100 Ti plants to keep track of the names also.
