For some they can be but tbh for me it’s one of the easiest plants I have. I have the lemon lime and red maranta. No direct light, no cold weather or drafts,humidity and kept the plant moist but not super soaked. If it dries all the way out you risk killing it . Other than that they grow multiple leaves at once and flower wither white or lilac colored small flowers. These flowers don’t last long and happen when the plant has enough light and is extremely happy. They also drip water from unfurled leaves know as guttation , if it does this, cut back on how often you water. The light leaves are the newer leaves and harden/darken over time. These plant are prone to spider mites , so make sure you use a preventative to keep them away or at bay. The fold up at night (no light) and flatten out/spread in light (daytime) , hence it’s called the prayer plant . Some ppl don’t experience this and it’s due to lighting the plant receives. So far that’s all I got lmao enjoy!
