The Marble Queen Pothos is a popular plant in the hardy pothos family. While it will survive in low light, if you want to keep it in better shape and retain the white variegation then find a bright area for it away from full sun. Water regularly in the growing season, around once a week, but less in winter months.
"All green new leaves?
Marble Queens can adapt to slightly lower light but to do so it forgoes the variegation allowing it to produce more chlorophyll to make food with. Move it to a brighter spot (avoiding direct sunlight) to get more of its pristine white variegation."
