Someone my husband works with gave him a lot of Azalea seeds. I don't know much about flowers so would like to know when I should plant these seeds here in Missouri. They are all different colors and the guy that gave him the seeds planted his along the road by his country cottage. We drove out to the cottage and they are beautiful. They didn't look like bushes but more like a thick row of flowers. Do they come back each year or do you have to save the seeds and replant them every year? We bought some land in the country also and that is where I would like to put them. Any information I can get about what to do with these seeds would be very much appreciated.
