Although they're known for their shade-tolerance, most hosta varieties perform well when exposed to a bit of morning sun and afternoon shade. Too much sun exposure will result in burned leaves, starting from the edges inward. The leaves will look brown, dry, and papery. Too much sun exposure also causes colors to fade.
Do any hostas like sun?
Though they are considered shade-tolerant plants, most will not thrive if grown in deep shade. Many hostas are more vigorous and will show best colors when given some exposure to sun, such as morning sun with afternoon shade. ... Late afternoon sun will most likely be fine too.
How do you keep hostas in full sun?
In all growing zones, hostas for sun thrive best when they have plenty of moisture. Plan to water sun-tolerant hostas more than their cousins growing in cooler, shady conditions. Also, maintain a thick layer of mulch over the soil on sun-tolerant hostas to help conserve soil moisture.
