Switch Grass
Panicum, or switch grass, is a North American prairie grass whose delicate, cloud-like panicles bring a haze of fine texture to arrangements. Cut fresh, its shimmering green or wine-flushed sprays soften the edges of bouquets and lend an on-trend, meadowy looseness; dried, it holds a feathery, glinting form. Cultivars range from clean green to burgundy-tinted, so it slots into palettes from fresh spring to moody autumn. Airy and forgiving, it is a favourite filler for garden-style and installation work.

Recut stems and plunge into cool, clean water for several hours; remove foliage that would sit below the waterline. Fresh panicum is a thirsty, short-lived cut, so change water often and keep it cool. For lasting use, harvest as the airy panicles open and hang small bunches upside down in a warm, dark, ventilated room until crisp.
