@sunflower-sim wanted these so badly, so I decided to upload them! These are signs that you can stick by your plants so that your sims know what plant is what! They are smaller than what the preview pic shows, but a little SHIFT + ] always works wonders!
Things you need to know:
You will need the MESH by yumesims. The specific file is yumesimsgoksikgardensigns.package, if you didn’t want to download the entire set.
It costs $1! That’s a bargain.
There is a sign for every gardening plant in TS4 except the trees, OR and GTW plants. (Chrysanthemum is huge!)
