Common questions
Is it safe for cats and dogs?
Yes. Ctenanthe is in the prayer plant family and is listed as non-toxic to cats and dogs. A pet that eats a lot of any plant may get a mild upset stomach, but it won't be poisoned.
Is it a calathea?
It's a close cousin. Ctenanthe and calathea are both in the prayer plant family, but ctenanthe grows faster, taller and is usually a bit more forgiving.
Why are the leaf tips turning brown?
Usually dry air or minerals in tap water. Raise the humidity and switch to filtered or distilled water.
