I recently picked up a copy of Planting A New Perspective by Piet Oudolf and Noel Kingsbury. It is a wonderful book. I was immediately compelled to search the internet for a source of seed of Stipa pulcherrima after seeing how incredibly delicate and dramatic it is while flowering. My question concerns hardiness. I am in zone 5b-6 and although the grass was listed as a hardy perennial by the seed vendor I am unsure just how hardy this grass is. I don't believe that many species of Stipa are grown in this zone because we are just slightly too cold.
I hope I don't have to resort to growing this grass in a large pot and keeping it in the cold room during the winter. I think it would be much more affective if it were included right in the landscape vs in a pot.
Is anyone growing this grass? I would love to hear about your experiences with it.
