Quick Overview:

‘Casca11’, sold under the trade name of BEYOND BLUE, was discovered in 2002 by Annemarie Blom of Haarsteeg, The Netherlands as a naturally occurring mutation of Festuca glauca ‘Elijah Blue’. It is an evergreen to semi-evergreen grass with a compact, dwarf habit that grows 3/4 to 1 ft. tall and 1 to 1 1/2 ft. wide. It has slender, cascading foliage that is intensely silver-blue throughout the growing season.

Description

Easily grown in average, dry to medium, well-drained soils in full sun. Tolerates light shade, but best foliage color is in full sun. Tolerant of drought and poor soils. Intolerant of wet, poorly-drained soils. Foliage is semi-evergreen. In St. Louis, the foliage may retain good color in mild winters, but clumps will show considerable browning in harsh winters. Clumps tend to die out in the center and need to be divided and replanted or replaced every 2-3 years. Cut back foliage in early spring to 3-4″ to tidy clumps and to facilitate emergence of the new leaf blades. Clumps may decline in hot, humid summers, and should be cut back if such occurs.
