Pennisetum Rueppellii (Pennisetum setaceum) is a lovely deciduous perennial grass that is treated as an annual as it is only winter hardy to about -5°C.
It forms a tuft of green foliage, then produces panicles of fluffy pinkish/crimson flower heads in summer that last well into winter. It grows to 70cm tall and adds texture & colour to cut flower arrangements and is also excellent dried. Looks fab in the garden as well.
