Albomarginata should be spelled as ONE word and most of the hostas with this name also have another. Albomarginata literally means white margin. You might want to look at the characteristics of all those and then ensure you get the one you want. Also the hostas that Gerry listed vary a lot in size and some are real slug magnets ('Invincible' for one).
You might also want to check Don Rawson's list of sun tolerant hostas. You'll find his lists at

Finally, you are in a warmer zone than some of us. Some hostas will grow in full sun in my zone but won't where the sun is stronger.
These are the ones listed in the MyHostas.be database
