Maranta leucaneura 'Lemon Lime', Prayer Plant or Lemon Lime Maranta || 6" pot
Maranta leucaneura. Surprising easy to grow, given how fancy it looks! The striped leaves lay flat during the day, then tend to fold together at night. In prayer. Get it?
Prayer plants aren't too picky about light but in direct sun it will scorch. If the color starts to look washed out, move it to a less bright spot. They can tolerate lower light levels, but I wouldn't push it too much. They like relatively moist soil, so water it (with room temperature water) just before the top of the soil dries out. The leaves will scorch if it gets too dry.
These are pretty slow growing and won't get very tall, so they're perfect for your shelfie. They're in a 6" nursery pot.
