Sterile Cultivars??


Festuca glauca 'Elijah Blue', Aug. 12, 2011 at Lovegrass Farm
I have read that 'Elijah Blue' is a Sterile Cultivar of Festuca glauca.  Have Fellow Gardeners found this to be True Or Not?  We've never noticed it to seed out for us but we've had gardeners lamenting that their blue fescues seed out.  I have a photo taken at the Botanic Gardens in Denver last Fall where you can visibly see the fescue seeding out but I'm not sure of the variety.  Wish I had taken notes, but like a kid in a candy store I was overwhelmed by So Much to See in a few hours!  We've never had a lot of seedheads on our fescue plants.  I've also read that the color looks more vibrant with the seedheads removed.  That makes sense for the plants' energy would be used for continued growth instead of making seed but I happen to like the look of the seedheads.   Our Native variety of Deschampsia cespitosa definitely does seed out but I've never noticed that happening with the cultivar; Deschampsia 'Bronzeschleier'.  All it takes is a little hoeing out to get rid of any of these unwanted seedlings so I personally do not consider it a problem.  Curious to know what other gardeners' experience has been!
