Kevin Vaughn 1983. Known as Ani Machi from Japan which has been confusing. Light green, glossy leaved with dark green margins. The leaves have a twist. Lavender flowers in August. Shade to half sun. We have a very nice display plant in the garden, lower path, just before the big willow trees, mid-garden and on the left coming down from the Marshfield village side of the garden. Take a look if you are down there.  Available potted and via mail order.
