Where ever someone gardens with perennials they learn, quickly or through trial and error, that some plants in a genus perform better for them than others. When it comes to gardening with Hostas in central Oklahoma, many gardeners begin to realize that the most popular, most readily available variegated Hosta [Hosta 'Fortunei Variegated'] is not necessarily the variegated Hosta they want in their garden. This hybrid complex in its various forms is often very susceptible to leaf burn and is frequently attacked by slugs.
A gardener out here on the Southern Great Plains would be much happier with the end results if they chose a variegated Hosta that has thick leaves with some kind of pronounced texture. Hosta 'Sagae' fits this description nicely and has always been a good choice for our area.
Having said this, it is easy to say H. 'Sagae' is an exceptionally handsome plant. Its 10x12 inch leaves emerge early in the growing season... they are wavy and have irregular margins that are bright yellow. Instead of a mounding form the leaves form an upright vase shape that can get 24 inches high and 36 inches wide.
This Hosta likes well-drained soil, heavily amended with organic matter. It looks best if protected from summer sun from noon to 4PM and drying summer winds.

The plant used as an accent and groundcover at the base of these Hostas is a Heuchera commonly called 'Palace Purple.'. This too is an excellent perennial for use in central Oklahoma. Its deep purple red foliage color is a striking contrast to the foliage around or near it... and you should know the foliage will retain that color best if this plant gets a good dose of direct sunlight each day. I planted 2 specimens on the west side of my home and have realized throughout the season that those 2 plants retained foliage color and overall health better than the same plants in lots more shade.

This plant combination would work as well in Oklahoma gardens as it does in this photograph... taken at the Missouri Botanical Garden in Saint Louis.
