Why does my Persian Shield wilt in the sun /afternoon. The tag that came with the plant read it needed 3-6 hours of sun. But it wilts with that much sun.
Since you are in the southern region you should try for morning sun and afternoon shade.
Container plants will need daily water, even twice a day if temperatures are above 80 degrees F.

I have two Persian Shields that are both exhibiting the same thing. The top growth seems fine and healthy, but as you go closer to the soil, new small leaves have browned edges or tips and often turn pale pink and die. I saw this same pattern in Persian Shields at a botanical garden so wonder if this is just what happens to the shaded leaves toward the bottom of the plant? I don't see evidence of any pests. I'm in Southern California and the plants are outside on a balcony where they get mostly bright shade and a little direct sun. Any help you can provide will be greatly appreciated!
If this is the only problem that you are seeing, then I don't suspect there to be an issue. At the very least, you can try to increase the light just a little bit, and this may help some.

I have a house cat and only have non poisonous plants inside. Would love to have this plant,but can not find out if it’s toxic.
Though I can't find anything specific to cats on this plant; it is listed as poisonous to people; can cause contact dermatitis-do not ingest.
I would advise you not let your cat eat it and consult your vet.
I bought a Persian shield hoping to put it in my aquatic pot, and I was wondering if it can grow in water permanently with roots.
Since it is a moisture and humidity loving plant, it should be an excellent candidate for water culture.
