Joseph, I agree that pencil is best. Tried and true and simple. The key to label longevity is to HIDE THE LABEL as much as possible, so that just the top edge shows, whether in the open garden or in containers. If you have an accession number system, be sure to write the number (or most critical info) at the bottom of the tag as well as the top end. Info on a buried label or portion thereof is nearly invulnerable to most disturbances. I have gone through many thousands of labels and have settled on vinyl-based material and pencil writing. Labels do not need to be visible for horticultural practice and 'hiding' them eliminates most of the problems of longevity.
