Q.Hosta placement
I have seen some pretty placements of hosta that complement each other. do you have a suggestion what to plant in an area about 18 feet long and 3 feet deep gets an east and south sun up against the house. what would be a nice grouping. i see some hostas that are stand alone and don’t look very nice, usually the two tone green.

Here's an article with the names of different hosta plants.

However, this is likely too sunny of an area for hosta that thrive in a shady area. You would need to water them more to prevent scorching or plant shrubs in between that would give them some shade. I would find a shadier location for your hosta and plant some nice foundation shrubs for zone 5.
