Your reply was spot-on. In what world are plants considered “seasonal and holiday decoration”?
I hate overbearing landlords and HOAs like these, what miserable people. As long as it’s not a hazard or obnoxious who gives a crap? On a plant-related note, my parents once got a written notice because they were planting flowers and had a bag of soil under the bench on their front porch. It couldn’t have been there more than a few hours but apparently it was too much of an eyesore for the community. 🙄
