If it is sunny, you want sun tolerant hostas. There are some but not tons. Most hostas are shade lovers. Hosta from seed will take too long before you see anything of any size.....years. Hostas are not bulbs but they are often sold early in the season as dormant starts. And if still dormant, they can be planted now. Some of mine are still dormant (or mostly so) while others have already emerged.

And there is a dedicated Hosta forum here I have linked to. Post your question there and they will give you all sorts of suggestions.

Seems to me like the more expensive the hosta, the more delicate its constitution is. So I'd get plain old green cheap hostas and try them. Sometimes you can get them for free if someone is dividing theirs.

Here is a list of Sun tolerant Hosta from Don Rawson's invaluable lists.

Without a doubt in my mind the most sun tolerant hosta ever is JUNE! I’m in zone 5a, northern Illinois. My June hosta get at least 6 hours of direct sun with NO signs of sunburn foliage, and minimal extra watering. Check this one out! Another bonus, it’s easy to find.

I have found Golden Tiara to be the most hardy and prolific of all my hostas. Mine (photo attached) get about 3-4 hours of early of early morning sun and grow (and spread!) like crazy. I have divided them MANY times and they just keep coming back and filling in the bare spots. (That's Love Pat in the middle of the mass planting.)
