Aciphylla squarrosa is native to New Zealand is found in both North Island and South Island in coastal to low-alpine areas from East Cape to North Canterbury. A. squarrosa can withstand temperatures down to -28º C.
It forms a dense cluster up to the 1m high of spiky three-pinnate leaves. The narrow blue-green leaves are highly divided with rigid serrated or crenulated margins and midrib and with pungent tips. These will pierce tramping boots. 
During November to January sweet-scented star-shaped yellow flowers on a compound, umbels are carried on a stalk up 1 m high. These stalks are also covered in razor-sharp spears presumably as a defence against animals such as the now extinct moa from eating it.
