Every plant comes with a label that tells you the botanic and common name and details about planting and positioning, etc. Some may think it’s a useful reminder if they are left on the plant once planted in the garden. Wrong.
They go brittle, that cherished printed information will fade and if they’re on a bit of elastic will just blow away in the wind at some point. In a recently planted up garden I was in almost every plant still had its label on. Some had become buried in the soil and had to be cut out. To me it looks amateurish.
I once saw a label left on a silver birch tree. As the tree grew and the trunk got fatter so the label became tight. The bark of the tree then actually grew around the label so that it became incorporated within itself, with a bit left half sticking out. This is very bad for the tree and again looked awful.
Much better to keep a spreadsheet or list or plan safely indoors that will tell you for always what is planted where. If you have had a professional garden designer or plants designer involved they will leave you that anyway.
Or you could take photos at the time of planting with the label in situ and then remove it.
Just don’t leave them out in the wind and the wet. They weren’t designed for that.
