    Back in summer of 2003 I bought three Blue Oat-Grasses from Limerock Ornamental Grasses, a mostly mail order nursery of ornamental grasses that was also a local nursery, that used to exist in Port Matilda, Pennsylvania by mail as tiny plants in tiny pots. I planted them in the front yard area. Here in 2019 the three are still looking good. I did have to dig up and reset one that had part of the clump die out. They were thriving better when there was less shade due to the trees growing larger, but they are still fine with some part shade. This is a lovely plant from Europe. In winter it is a brownish-blue evergreen plant. I find this to be a more reliable choice than the smaller Blue Fescue grass that is sold much more often at conventional nurseries. Some larger, diverse conventional nurseries and mail order nurseries sell this species. I only see it infrequently in the Midwestern or Eastern US, as it is largely unknown.
