Uniquely identifiable characteristics

Distinguishing Feature :

Unlike the native Galingale (Cyperus longus) Pale Galingale is about 2/5ths the height and is a naturalised neophyte, often found in parks and gardens as an ornamental plant. It also escapes to grow in rough ground, roadsides and besides water. It can also be spread by wool from sheep and by grass seed which might have some fruits of Pale Galingale amongst them. It is native to tropical America which is why it is sometimes called American Galingale.

It is to be found in south Britain and north to Dumfriess, IoM, Southern Ireland and in the Channel Islands.
