Alert Gardeners Gail and Ellen brought up a horrible new practice at the big box stores. Spray-painted cacti and succulents. If this isn't plant torture (and eye torture) I don't know what is:
No idea if it actually kills the plants but I'll bet it doesn't enhance photosynthesis or respiration. Remember Jill Masterson from the James Bond film "Goldfinger"?? 'Nuf said.
Maybe we gardeners should start a "Keep Plants Green" campaign??
