Strelitzia nicolai is a giant that wants more direct sun than almost any other houseplant — several hours a day if you want the leaves to stay upright and eventually flower. Split leaves are normal and healthy: it's how the plant lets wind through in the wild. Feed through spring and summer for fast growth.
