We write our plant tags out by hand on discarded vinyl blinds with indelible markers, and there’s always the internal debate of whether it’s better to be informal and recognizable or technically correct (because writing both gets tiresome). Personally I lean towards accuracy rather than approachability because technically correct is the best kind of correct, but even my plant friends think I’m a nerd. Who’s with me?
Nasturtium, Rhododendron, and Tradescantia are commonly used in our neck of the woods too. I sometimes wonder what the driver of that parlance is.
