Nice plants but wrong info

I took my son with me to pick up water and soda for our vending
machine the other day at one of the local wholesale clubs and saw
several racks of these dahlias and a rack of coreopsis limerick ruby.
Although the plants were pretty nice, it was the accompanying signage
that upset me. The sign called them perennials that will bloom every
year. (so did the sticker on the pot). I get upset for the beginning
Gardener who picks these up with the intentions that they will come up
every year. They may think it was something wrong that they did, not a
miss-labled plant.
