I want to grow in my gardenDude, that is not easy actually to grow bell shaped flowers because they are mostly very weak flowers and need special conditions t grow. But there are many types of bell shaped flower in the world, so some of them are good for room vase. You have to put him on sunny place anyway, because it is a spring flower and it needs a lot of ultraviolet light. So strictly don`t recommend you to put them into dark place. And also watering should be moderate. Don't water them every day. 2-3 times a week would be enough, depends from the size of flower. I have at home siberian bell shaped flower. I really like them.
