Absolutely ideal for growing in decorative containers, this hardy Red Switch Grass is a perennial substitute for Pennisetum 'Rubrum'. Measuring in at just 3ft (2ft before blooming), 'Cheyenne Sky' forms a tight, vase-shaped clump of blue-green foliage that begins turning wine-red in early summer. It makes a dynamite specimen plant and is even more eye-catching when planted en masse, for screening and alongside ponds or streams.
