Elymus magellanicus - Blue Wheatgrass,
aka Agropyron magellanicum, Leymus magellanicus
Blue Wheatgrass is reputed to be the bluest of all grasses. From our
observations this seems to be true.
Grows well in containers.
Muriel says: My garden was on our local Garden Tour. Of
all the plants in my garden, this and Persicaria
polymorpha received the most attention. This plant does
not like to be dry. If it dries out it will turn beige.
It may or may not have died but it is letting you know that
it doesn't like to be dry. To be honest, I think that the
drought tolerance rating of 3 may be too generous.
