Did you know you could buy hostas for sun? Despite being called full sun hostas, these plants aren’t like a coneflower or daisy that can take eight hours of intense sun. Rather, hostas that withstand sun are referred to as sun tolerant hostas. That means they can take some sun — definitely a little more than most of their shade-loving hosta cousins — but still need protection from hot afternoon sun. Hostas for sun share some common characteristics.
Many of the sun tolerant hostas tend to have thicker leaves. Often the full sun hostas also have very textural leaves with patterns that are embossed, puckered, pleated, wrinkled, or ruffled. Botanically, these leaves are described as being rugose. Many gardeners refer to these types of leaves as corrugated. Hostas with rugose leaves also tend to be more slug resistant.
Examples of rugose type hostas for sun include Hosta ‘Sum and Substance,’ Hosta ‘Guacamole,’ Hosta ‘Stained Glass’ and Hosta ‘August Moon.’ Many of the Hosta fortunei hybrids and sports also have rugose leaves, including Hosta ‘Fortunei Hyacinthina’ and Hosta ‘Fortunei Aureomarginata.’
Many hostas with fragrant flowers fall into the sun tolerant hostas group. These hostas usually have a touch of Hosta plantaginea in their family tree. Hosta plantaginea, which is a sun tolerant hosta, is a Chinese native that opens white flowers in late summer at dusk, releasing a heady perfume. Other fragrant varieties of hostas for sun include Hosta ‘Ambrosia’ and Hosta ‘Fried Green Tomatoes.’
Hostas for sun also feature many varieties with gold or yellow tone leaves. These lighter colored hostas do tend to burn in full sun, so plan to provide protection from the hottest afternoon sun. Hosta ‘Sun Power’ unfurls bright chartreuse leaves that splash gold into a planting, while Hosta ‘Fried Bananas’ brings a real glow to any landscape with its shiny gold leaves.
The thing to know about sun tolerant hostas is that while they withstand more sun than traditional shade-loving hostas, they do need protection from sun during the hottest part of the day. In Zone 6 and north, hostas can tolerate more sun than in warmer zones. In the hottest zones, even sun tolerant hostas will have a tough time withstanding more than a few hours of 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 mulch over soil on sun tolerant hostas to help conserve soil moisture. As you plan which hostas for sun fit your landscape needs, visit local nurseries in August and check out the hostas. The ones that don’t have burnt leaves are sturdy sun tolerant hostas that you can count on to perform in your yard.
