I purchase several Bonsai seeds. I've only been doing Bonsai for approximately two years. So I'm pretty new to it. Over the last year-and-a-half I've purchase some seeds some of which have been successful. I've had a bonsai Sprout that I cannot identify because it was a seed that I thought was not going to grow so I planted new seeds. Can someone please help?

You did not buy bonsai seeds, there is no such thing. What you have is a seedling but I am not sure what species of plant it is. If you are interested in bonsai then buy a tree that is already a few years old, you will have something to work with much quicker. If you must grow trees from seed then go out and collect them, then you will have some idea of what they are.

Contrary to what you might think bonsai are not grown from "bonsai seed" ( normal tree will grow out of whatever seed you bought), nor by placing them indoors in a pot with some pebbles .
I think you should start studying first, get a general idea and in the mean while try to keep your sapling alive.

Looks like azalea seedlings
