Very nice Alyssa! Croton (Codiaeum variegatum 'Petra') is a common landscape plant here in Florida. I've grown it as a container plant over the years but mine always stay outside year round so I can't offer advice on misting or indoor care. I think we have a few members who grow Croton as indoor plants so hopefully someone will be along with suggestions for you.
