I'm "try to label." Will use the markers that come with the plants, but they deteriorate and get buried or shifted when the neighborhood feral cats decide my beds are litter boxes.
Got EON markers from Mamajack and Susan in the spring and I like those, but Sharpie fades fast in Texas summer sun. My brain has a thicker than ever Teflon coating now, so remembering what I got and where it is and such is extremely unlikely. Especially since I have gone daylily crazy this year and bought 80+ , the names for which I will NEVER remember by myself.
So, permanent markers it is and look for a paint pen and a grease pen.
