I have two papaya plants I grew from seed in my kitchen (I have a large greenhouse window). One is over 7 feet tall and has had one papaya, but it is now touching the top of the window, and it really needs a new, taller home. I did move it upstairs to where we have a cathedral ceiling in one room, but there was not enought light and it wasn't happy, so I moved it back down. The sencond plant is about half that size and has blossoms. Not sure whether it is female or hermaphrodite yet. If hermaphrodite (as the other one was), it should fruit with no problem--otherwise, it will need a friend in bloom.
Then, I have lots of orchids, some African violets Christmas cactus, and lots of carniverous plants. I got the latter to take care of the fungus flies that come with the territory of growing house plants. Some people think it's a little odd that a vegan would keep carniverous plants, but, it saves my killing all those little flies. And they are fun to grow.
I keep the warm growing orchids in the house, but put them out when it rains. The cool growing ones are outside all the time. I don't put the other houseplants out because they do better inside.
