I found it difficult to start from seed, but the plant seems to require no care at all, beyond occasional watering. I have no other conditions to compare it to, but mine gets 1-3 hours of direct sun per day (midday!), and bright shade for several more hours. No info about cold weather, sorry.
Mine sits in a tray with 1/2-1 inch of water, but that's just my cp training. If it gets uincomfortably dry, it starts to droop. If you water quickly at that point, it perks right back up.
