Hello! I received an English Garden basket with a variety of plants and flowers as a gift and I separated each variety out to itself. I started growing this plant in a small pot indoors and thought it was some variety of Caladium. We just moved to another house in the same town and, suddenly, this little guy has just taken off, growing like crazy, putting out shoots and becoming very "viney". Now, I'm not sure if it's a Caladium, or not! The viney appearance is what is throwing me. I transplanted it to a bigger pot just this morning, and I added a stake for the vine to attach to, but I'm not sure if that's what I'm supposed to do! Could someone please ID this plant for me, tell me what the ideal growing conditions are and if I should separate the shoots or just let it keep growing, as is? Also, can it be planted outdoors in zone 7a/b? I would appreciate the ID and any growing/maintaining advice you might have!
