Salvia glabrescens 'Shi Ho'
This is a beautiful form of Salvia glabrescens. This was found in a nursery in the USA, and the picture was kindly provided by Joseph Despins. This Japanese Salvia can be blue, pink, pure white, or purple. None of the forms are easy to grow in the UK, as they flower just when the first frost is likely. They need a shady, moist area. S. glabrescens may set seed in the UK, but it can also be propagated by cuttings.
