The Story

Fescue—does that sound familiar? There’s a good chance that your lawn is composed of Fescue. This Fescue is a different species that forms neat clumps instead of spreading to form a carpet. Also, it loves full sun and low humidity. Native to southern France, it’s adapted to a dry, sunny climate. And of course, Blue Fescue is blue, blue, blue. Beyond Blue Fescue was discovered in a Dutch nursery, appearing as a chance mutation of the popular Elijah Blue Fescue. The new plant was bluer than Elijah Blue and had more of a cascading form. It was introduced in 2011.

The Details

Flowers—yea or nay? Beyond Blue Fescue sends up flower plumes in late spring. The dainty plumes are pale blue at first, eventually turning beige. Many consider them to be decorative and leave them on, but others prefer to maintain Beyond Blue purely as a foliage plant and trim the plumes off. The choice is yours.

How to Grow

Plant this sun-lover in an open space in light soil that drains quickly. Although Blue Fescue enjoys bright light, it generally isn’t a fan of high heat and humidity—although Beyond Blue is more tolerant than most. This cool-season grower does best in northern and western climates and looks its freshest during the cooler months of the year. It is semi-evergreen in mild winters. Cut it back to a few inches from the ground in early spring. It’s also wise to divide Beyond Blue every few years in spring to keep it growing vigorously. Simply dig up a clump, pull apart a few healthy sections with roots, and replant
