Use our Copper Wide Curl Plant Stick to provide support to the base of leaning stems or vines, while adding a modern, unique feature to your house plant. Our Copper Plant Sticks are made from Spun Copper which gives it a beautiful finish and makes it stronger than bare copper wire. As with any metal, some discoloring may occur over time with use and watering. The copper wire may develop a natural patina. If you prefer, you can clean and restore it with vinegar and a soft cloth.
