Krossa Regal is a big Hosta, but it’s more than just big—it’s grand, it’s magnificent! This specimen-quality Hosta has a truly royal presence. It’s quite distinctive, with a tight mound of blue-gray foliage and leaf margins slightly undulating. The leaves are held on long petioles (leaf-stems), so that the clump takes on a vase shape. In mid-summer, more drama: flower stems shoot up like a rocket, cruising up, up, up… until the big lavender blossoms are looking you in the eye. Duck! Here comes a hummingbird! This Spirit is so cool.

Hostas are native to Japan, China, and Korea, but they have many passionate fans around the world. Over the years, plant breeders (along with some home gardeners) have introduced new Hosta selections whenever they’ve found a plant with unique traits. As a result, there are now thousands of varieties to pick from! Large, small, blue, green, gold, variegated, upright, or spreading—there’s something for everyone. Krossa Regal was introduced to American gardeners in the 1960s, though it wasn’t officially registered until 1980. The late Gus Krossa of Livonia, Michigan, bought it in Japan and brought it to the States.
Hostas are simple to grow, but one challenge Hosta growers do face is slugs. Slugs love these succulent Spirits. Because Krossa Regal Hosta has such thick, waxy foliage, however, it is largely slug-proof! They tend to shun it and go elsewhere in search of easier meals.
How to Grow
Hostas love shade, and Krossa Regal is no exception. A bit of gentle morning sun, however, will help to bring out the bluest tones. Water regularly. This Hosta does possess some drought tolerance when established, but it will appear lushest with plenty of H2O. Avoid overhead irrigation if possible, which washes off the blue coating. Plants will become blue-green in rainy climates. In deer-prone areas, treat with Plantskydd® to prevent grazing. Foliage will die back with the first frosts and can be cut back then. If you wish to dig and divide Krossa Regal, you can do it at any time, but late winter/early spring is best.
