THYSANOLAENA maxima - Tiger Grass:  2-3m x 1cm, -2°C - A bamboo like tropical grass  from Asian.  The large leaves, up to 7cm wide, are used to wrap food for steaming and the flower heads are tied together and used as brooms. The culms are also quite stout and would have their uses.  A very attractive plant that is a good substitute for small bamboos like B. multiplex (which are susceptible to unsightly scale insects) as a feature or hedge. Tiger grass will do well in full sun to light shade and needs ample water to stay lush. It is frost sensitive but plants here have experienced -2°C without signs of damage.
