It is known by the common names bulbous canary-grass[2] and Harding grass, is a species of grass in the genus Phalaris of the family Poaceae.
It is an erect, waist-high, stout perennial bunch grass with grayish to bluish green leaves. Flowering heads are dense, spike-like, and usually two to five inches long. It is slow to develop from seed, but can form large bunches after several years.[3] Phalaris arundinacea (reed canary grass) differs from Harding grass in having more distinct rhizomes and an inflorescence that is compact at first but later becomes more open as the branches spread.
How to get rid of:
