Hostas for Sunnier Locations

Are there any varieties of Hostas that would do well on a slope that doesn't get shade until late afternoon?

The American Hosta Society recommends the following cultivars for sunnier areas:

August Moon
Fortunei Aureomarginata
Fragrant Bouquet
Francee
Gold Regal
Gold Standard
Honeybells
Invincible
Minuteman
Patriot
Regal Splendor
Rising Sun
Royal Standard
So Sweet
Sum and Substance
Summer Fragrance
Sun Power
Sundance
Undulata Albomarginata
Undulata Univitata

These leafy plants will dry out faster in the sun than in their preferred shady location. Mulch the soil with shredded leaves, evergreen needles or other organic mulch. Check them often and provide enough water to keep the soil around their roots moist but not wet.
