I bought three Gerbera this spring. They bloomed awhile but need a lot of water, they were really too big and leafy for their pots and wilted a number of times, and bounced back. I moved them to larger pots but now they're slow in blooming again. They're said to be heavy feeders. Consistent plentiful water and food is probably the best bet in pots.
I don't think they'd do well indoors at all.
