I am unsure what type this hosta is as it was already planted when I purchased my house. It has always been just green but when I was out in the garden today I noticed one leaf with a white stripe and another with goldish streaking. Have you seen this before?
You MAY be able to divide them off, but if it affects only one leaf in an eye, it may just be an aberration of that leaf. Some plants like 'Allan P. McConnell', 'Lakeside Zinger' and 'Lemon Frost' do that sort of thing quite regularly, but aren't really sporting.
