Growing beyond Blue
For sun, soil, water and cutting back, the Missouri Botanical Garden's page for Beyond Blue repeats its species text, so the blue fescue page applies. The same shared text carries the species' limits: the plants are short lived, clumps tend to die out in the centre and need dividing or replacing every two to three years, and the foliage may decline badly in hot, humid summers.
Its summary for Beyond Blue differs from the species' in two places. Its American hardiness zones run one zone warmer than those it gives the species, and it calls the plant evergreen to semi-evergreen, where the species is semi-evergreen. It rates the maintenance medium, as for the species, where it rates that of Elijah Blue high.
No Australian reference read covers Beyond Blue, and none gives a frost rating or climate zones for it.
Using beyond Blue
The Missouri Botanical Garden's page for Beyond Blue gives it the species' uses and dense groundcover spacing word for word, so the blue fescue page sets them out: accents in rock gardens and at border fronts, edging along paths and borders, and groundcover over small areas. No reference read gives Beyond Blue a use or a spacing of its own. Where a narrower clump is wanted, the same reference gives Elijah Blue half the width of Beyond Blue.
What to check before you buy
Growers list this plant as Festuca glauca (Casblue) Beyond Blue. The Missouri Botanical Garden gives its cultivar name as 'Casca11', sold under the trade name Beyond Blue, and no reference read links the name Casblue to it, so compare listings by the trade name. The same reference records a United States plant patent for it. The listings on this page show the sizes growers list. For what to check in the pot, see the HortOS guide to nursery plant quality: roots, pests and hardening off. Stock that crosses a state border moves under the state and territory biosecurity rules on moving plants and soil.
