My girlfriend has several Narcissus plants in her living room. She loves the white and yellow petals!
I have never seen one of those before. Are they only grown indoors.
Depending on the climate you're in, an which hybridized species you have, which can vary, they could be either indoor or outdoor plants.
That is interesting. I love plants, but I have never been good at keeping them. I always forget to water them and they die.
Could be worse though. You could have good intentions and give your plants root rot from overwatering them.
I have seen that happen before to other people. I love my outdoor plant because at least it rains once in a while to water them. 
Yeah that's convenient! I love the Narcissuses that she has because it reminds me of the Greek myth about that guy who fell in love with his own reflection.
That sounds like a really interesting plant. My favorite flower is the iris.
