Another plant that thrives on neglect is the ZZ plant. They're popular in offices and other buildings without much sunlight, but they're starting to become a popular choice for homes too. ZZ plants have shiny, dark green leaves and long, thick stems that can grow quite tall. They're similar to cacti in that they don't need much water, but so much easier to look after in terms of light. Stick one in your darkest corner and watch it thrive!
