Hosta Kiyosumiensis is a dappled leaf hosta also known as the Mountain Hosta. It is native to Japan.
About Hosta Kiyosumiensis
The name of this hosta comes from our version of the name of Mount Kiyosumi-yama, a small mountain in Japan with views of Tokyo Bay. The plant grows on this Mountain.
In the northern areas of the mountain the habitat is quite dry and the plant is found on slopes in wooded areas at the base of other shrubs.
Further south it appears along rivers. For us, this fairly fast growing hosta is perfect for any shady garden spot.
A recent trip around the JR Raulston Arboretum provided me with a look at their collection of hostas.
I have a large collection of hostas in my shade garden, and this variety is one that piqued my interest.

General Growing tips for Hostas
Hostas do best in part shade in well draining soil. Adding compost helps to make sure the soil does not get too wet.
Some varieties can take a bit of sunlight, but most of them do not like full sun. Many types love to sit in the shade of large trees with other shade loving plants.
This perennial hosta is tough and versatile. Generally speaking, the plants with the greenest leaves are the most shade tolerant and those with more color and variegation can take the sun better.
As a rule, hostas start to grow quite late in the spring, but quickly fill in their allotted spots in the garden. Hostas may take 2-5 years to reach their mature size so keep this in mind when planting.
Fairly disease resistant but be on the lookout for slug and snails.
