Non-toxic green elves are harmless to cats. Green elf, also known as white butterfly taro, is a perennial evergreen vine. Stem nodes with aerial roots, from the middle of petiole base. When I was a child, the white butterfly taro was clustered and the back stem was elongated into a vine. Originated in the tropical rain forest area of South America, it has a strong nature, likes humidity and has strong shade tolerance. I also like the hot, humid and semi-cloudy environment, and I am afraid of the scorching sun and drought.
