When you start out, keep in mind you want fast growing stems to predominate. Don't plant the plants you want as your 'final' choices, that will often prove to be very frustrating.

Check out the sticky here for some good ideas as well as the plantfinder on the site here. Of the plants you mention, imo, I probably wouldn't plant much of the H. callitrichoides or the E. parvula to start with. I have no experience with M. tenerum. Hope that helps.
