Species Hostas come true to type from seed unless they were cross pollinated with other types.
Cultivars are another thing. Mostly revert to species types and colors. Every one should keep some species hostas in their beds if you have a large area. Good to show groupings. Growing from seeds is easy for me. I just toss them in a area I can keep a eye on. In the several years doing this. I only got maybe 3 or 4 variegated ones of some merit. I keep them to myself. There is already too many cultivars out there that look and act the same. Some one should be able to keep every hosta nursery from doing this. They all want to be glorified and praised for their greatness while the hobby suffers.
Paul's advice; I would check out the Tiara group. They been around for a while and can be had for a reasonable price. I have a few that grow very vigorous. Started with Golden Tiara and a lot puped out all gold or lime green. They looked great together. They make a great border.
