Gorse is truly an awful bush.
The Royal Society in the UK advised the settlers heading out to Australia and New Zealand in the 1800s to be very careful as to what plants and animals they introduced to these two new countries as they could not predict how they may respond to these new environments, but the advice fell on deaf ears.
NZ is over run by gorse, broom, ragwort, willows and has feral stoats, ferrets, weasels, hedgehogs, deer, pigs, possums, cats, dogs, wallabbies and various birds that have been introduced all to the detriment of that country. Gorse sold at 1/- (shilling) per bush in the 1850s in NZ!
Australia did just as badly, with foxes added into the mix for good measure!
End of rant!
Gorse is more likely. Unpleasant and thorny bush ...
