More involved markers, especially some commercially printed ones, may also include hybridizer, date of introduction, color class. I have tried several tools. The metal tag is a small round disk attached to the plant by a thin wire. There is argument that leaving the tag attached to a cane will kill that particular cane. Heirloom Old Garden Roses prints their labels when they receive your order, so the plant comes in with the variety name and your name on the label.
Some streamers are huge, with a picture of the plant in bloom, and care instructions on the back.
If you remove the label from the plant, there is no convenient way to attach it to something else, other than stapling to a wooden stake. The plastic stick labels are more durable. The chief drawback to stick labels is their tendency to be heaved from the ground during winter and blow about the yard. John Harmeling makes his own markers from old white metal window blinds. Cheap and quick, attractive and weather-resistant.
