I am getting conflicting reports from the internet (isn't that always the way): is there any sort of viola that will thrive as a houseplant? I'm looking for a small(ish) purple-flowering plant that will be happy in a pot indoors. African violets having such a finicky reputation, I'm wondering if any of the many real violet varieties would be suitable. Any suggestions, or should I leave these to the great outdoors? (It would take some willpower to avoid munching on the occasional blossom, in any case...)
