First, to dispel a common misconception, there are no sun hostas, no sun-loving hostas, and no sun-proof hostas. There are, however, hosta varieties that are able to “tolerate” more sun than their shade-loving cousins. Those are called “sun-tolerant” hostas.
It's important to remember that "sun-tolerant" does not mean they are drought-tolerant. Once a hosta's roots are mature that hosta will be much more drought-tolerant that a younger hosta plant. Hostas need consistent moisture to thrive. Sunlight is rarely an issue, but intense heat and dry conditions are.
Sun-tolerant hostas still need protection from the afternoon sun, especially the hotter sun of the dog days of summer. No hosta will survive long if planted in full, hot sun like a daisy or a sunflower.
An investment in a nice shade cloth will save your hosta from the intense heat. Those Sun Sails functional and pretty.
Here at Sunset Hosta Farm, we're in Zone 6. Here and north of us, sun-tolerant hostas can generally take four to six hours of direct morning sun but still must be shielded from the afternoon sun.
Sun-tolerant hostas have certain characteristics that allow them to be placed in that category.
Conversely, hostas with thin leaves will not take as much sun and the leaves can burn when exposed to too much sun Large leaves are able to absorb more water and hold it for its root mass.
Hostas with fragrant flowers, like 'The Shining' pictured above, have a touch of Hosta Plantaginea in their family tree which makes them more sun tolerant.
For these types of hosta to emit the best fragrance, some direct sun is actually necessary.
Where leaf color is concerned, generally the brighter the leaf color, the more sun the hosta can tolerate.
Generally as a rule, hostas with white, yellow or gold tones on the leaves can withstand more sun before the leaves will burn. Their yellow colors will appear brighter when given sun, and without the sun the leaves can quickly fade to green.

Where the blue hostas are concerned, in order to keep that gorgeous blue color as long as possible through the season, afternoon shade is mandatory. These blue hostas were bred to be able to take some direct morning sun, but even if the sun-tolerant blue hostas get too much sun, the leaves will turn green or burn. But not to worry, the blue color will return the next year giving you a chance to relocate the hosta until you've hit just the right spot for the color you want.

Best Care Tips for Sun Tolerant Hostas
At least one inch of water per week during the growing season with a good soaking periodically during the hotter summer months. If you're growing hostas in the hot, southern areas, consider installing a drip irrigation system to keep the hostas well watered.
Soaker hoses are always a good idea.
- Good drainage. Good quality soil with lots of organic matter will hold the moisture well. Avoid clay and compacted soil.
- Mulch. A three-inch layer over the soil will help to conserve moisture and keep the roots cool.
- Throw some shade. Supply some shade sources during the hottest parts of the year. A well-placed trellis, a garden statue or even another larger hosta can provide just the right amount of respite from the sun.

Duplicating exact planting conditions for a specific hosta is half-knowledge and half pure luck so experimenting may be necessary.
But since hostas are a very forgiving perennial, they will come back the next season to give you another crack at just the right placement. Once you have it, though, your hostas will give you many years of added beauty to your garden.
