'Joseph' - Joseph's Idaho Fescue
We are very pleased to offer this variety of Idaho fescue.
The strong blue-green colour sets it apart from the more
electric blue of Festuca
idahoensis 'Siskiyou Blue', yet 'Joseph' is more ornamental
than the common green varieties. When you combine this unique
colour with the form, it is truly a beautiful Western native.
Like many of the grasses of the arid West, Idaho fescue
will take a few seasons to take hold, but once established,
a mature stand of F. 'Joseph' is very durable.
This fescue, like all fescues, is well behaved in the border
and looks great massed or in large drifts. Be sure to leave
enough room to allow for air movement between plants.
Note: the larger fescues, because of their fibrous roots,
tend to suppress the growth of plants in close proximity,
so do not crowd the plants.
