Festuca species
Zone: 5-9
Height: 6-18 inches
Two varieties are of interest in the garden: Large Blue Fescue
(Festuca amethystina) and Blue Fescue (Festuca ovinia
var. glauca). Fescues are mound-forming, semi-evergreen perennials
used as accent and specimen plantings in the foreground of borders
and in rock gardens. Large Blue Fescue is hardier than blue fescue
and should be considered in zone 4. Fescues are grown for the blue
gray foliage. The flowers are insignificant and should be removed
to help retain the mound like effect. Both fescues must be planted
in well-drained soil in order to grow their best. They tend to die
back in hot, dry weather and should be watered to prevent browning
of the foliage. In heavy, poorly drained soils fescue tends to die
out in the center. It should be divided frequently to maintain vigorous
growth. Spring cleaning should be limited to raking out and removing
brown foliage. Cultivars to look for: 'Bronzeglanz' and 'Elizah
Blue'.
