You keep mentioning live Christmas trees on Twitter and in AskJudy. What do you mean by that? I would like to get a live Christmas Tree but don’t know what it is?
Norfolk Island Pine Trees (living Christmas Trees), sometimes simply called Star Pines or Norfolk Pines, are stately symmetrical evergreens that thrive indoors in very bright light. Many people do use Norfolk Pines as living Christmas Trees, but be careful not to dry them out with too many lights. Norfolk Pines come small enough to sit on a table and large enough to fill the corner of a large room with tall ceilings.
These plants need very bright light and should be turned often so that they stay symmetrical looking. You can read all of my care tips in the Popular Houseplant section of the website: https://www.houseplant411.com/houseplant/norfolk-island-pine-how-to-grow-care
These plants are not considered poisonous but if a child or pet eats the pine needles it will cause severe stomach problems. Read more about common houseplants that are poisonous in Don’t Feed Me To Your Cat! A Guide to Poisonous Houseplants
