Calathea concinna 'Freddie' || 4" pot
This just might be my favorite plant (today).
Freddies can tolerate lower light levels, but of course, won't say "no" to medium light. Too bright, though, and the leaves will scorch, so keep it out of direct sun.
Like most calathea, these like humidity and to be a bit on the moist (but not wet!) side. If the leaves start to brown around the edges, start spritzing it or give it a vacation on the bathroom for some humidity.
Pet-friendly, calathea are not known to be toxic to pets.
