Hi Nancy.
I have had great success with Amaryllis bulbs. I grow them in pots and have for years. They multiply and always come back. I have also had success starting them from the seeds the plants produce. To think I used to toss out those Christmas presents of Amaryllis bulbs after they bloomed never realizing what a great plant they can be.
Usually daffodils just bloom one season for me. Sometimes come back but not too well. I have had good success with getting Hyacinth to come back year after year. These I grow in pots as well.
My Cannas have done well in pots but grow too fast and too big sometimes.
I have had only moderate luck with rain lilies. Maybe like you said they are getting too much sun.
Thanks for starting this site. Our forum is pretty dead, sadly.
