What are the pros? Big pots, sun, heat
What are the cons? Too much heat, frost.
I grow these in 5 gallon pots on my back porch in Phoenix, Arizona. I have used seed starter mix and plain ordinary potting soil. They germinate quickly and grow fast. If the pot is big enough, the weather 75 and they get 5 hours of direct sun a day, they will easily grow 3 feet tall with huge beautiful leaves. If they get enough sunshine, they will be stout and strong, not at all spindly. They are rather large plants and don't grow well in smaller pots. Even a one gallon pot will stunt the plant. They like sunshine, and will be a bit spindly if you grow them in the shade or indoors.
They grow best when the weather is between 80 and 100. When the temps exceed 100, they will slow down, maybe wilt a bit, but they always survive our Phoenix summer days of 110 day in and day out. They will survive winter unless it freezes - a frost will kill them.
They eventually bloom, and gathering seeds from them is very easy. No two plants look alike, but their colors vary considerably.
