Cotton deergrass (Trichophorum alpinum)

Cotton deergrass

Also known as: Alpine deergrass, Hudsons bay clubrush

Alpine bulrush (Trichophorum alpinum) is named for its native mountainous, boreal habitats where it distinctive white tufts can be seen growing in peaty bogs and on calcium-rich soils. These small flower spikes are quite different to those of the other, larger bulrushes, so it's quite easy to differentiate cotton deergrass from its relatives.
