I am very partial to blue foliage and when it comes looking like a big plump sea urchin I can’t resist. I know that this plant will have a hissy fit in the heat and humidity and may even give up and die on me but I just can’t resist it and I am always on the look out for a source to ensure its presence in my garden. The blue color of the low growing tufts stays true all summer (unless it dies) and adds a fine spiky texture to the front of the border. The rather inconspicuous soft pale gold flower heads that develop in June add interest but I would grow this plant even if it didn’t produce any. It’s a cute plant…what more can I say?
Type: Grass.
Bloom: Inconspicuous pale gold flower heads produced in June.
Size: 6-10” H x 12”W.
Light: Full sun with afternoon shade in the South.
Soil: Poor, well drained, neutral or slightly alkaline soil.
Hardiness: Zones 5-9.
Care: In early spring cut back the foliage back 1-2” above the crown. Remove seed heads as they develop; the plant will reseed itself but the seedling will vary in color from green to blue. Do not fertilize or over water.
Pests and Diseases: May wane and die off in heat and humidity.
Propagation: Divide in spring or fall; seed may not come true in color.
Companion plants: Lovely with pink flowers such as Dianthus spp, cranesbill (geranium spp), evening primrose (Oenothera speciosa) and with the foliage of ‘Burgundy Glow’ ajuga.

I have three of the blue/grey Festucas but I’m afraid they never seem to do well here despite what should be ideal conditions. All three are hanging on but not really increasing in size. A pity because they are very impressive when at their best. Some plants are not meant to be, even though I find it hard to accept!
I am surprised to hear that they do not do well with you. They are very pretty here when it is their season (spring to early summer) but they get pretty ratty the rest of the time when temperatures and humidity are soaring.. I love them for what they offer when they are at their best.
