Festuca glauca 'Casblue' INTENSE BLUE^®

Blue fescue is an attractive perennial – grass forming low mounds of short, thin foliage of various shades of blue colour. It grows only about 20 cm tall but in summer is overgrown by about 40 cm tall stems with light beige spikes of flowers. They can be removed at any time if blue foliage is the key feature in your landscape design.

INTENSE BLUE^® is a blue fescue of a striking colour. It was bred by Allure Tuinplanten and Amigra from the Netherlands. It was found in 2005 and introduced three years later. The plant makes well-behaved, symmetrical, extremely dense tufts of silvery blue foliage. Their colour literally calls for combination with red, yellow, and fresh green plants of similar dwarf habit (leucothoe, hebe, hakonechloa, or ground-covering junipers). We recommend dark background such as lush brown pine bark mulch rather than light coloured gravel where plant's colour might not do it any justice. Blue fescue also looks adorable in a handsome pot where its fine foliage slightly arches over the pot's edge.

Blue fescue is evergreen, however, after a bad winter some of older foliage might be exhausted and unsightly. Do not cut the whole tuft but gently comb them out to make room for new leaves which emerge quickly after your help.

Fescue is not as easy to grow as it might look. It is very picky about soil – it needs to be free draining, preferably poor, of neutral or acidic pH rather than strong alkaline. Wind or hard frosts don’t matter if the ground is dry in winter. Place it in full sun and divide older clumps in early spring to avoid dying off from the centre. Under ideal conditions it is hardy to about -34°C (USDA zone 4).
