Yellowing leaves and stems
Thank you for your question. I cannot immediately identify the species of plant, but I'm wondering if you have fertilized it since you got it? Plants' leaves become yellow through a variety of ailments (and insects), but the first thing to rule out is a lack of nitrogen, resulting in chlorosis. ( https://extension.unh.edu/blog/fertilizing-houseplants) Houseplants can also get too much or too little light, depending on the species . If you have the plant label, or recall what it is, you can do a web search for its specific needs.
Hope this is helpful. Good luck!
