Hello Lisa,
I’d be interested to know which months your ‘yellow season’ occurs? There are two species of gorse Ulex europaeus and U.gallii – the former flowers from March to June and the latter flowers from July to September. U. europaeus also flowers sporadically during mild winters. But you probably know this already!
Ireland is the answer to your question.

Thankyou Chris,
That’s very interesting and you’d wonder why introduce a weed?
Coincidentally, there was mention on the radio of goats and their liking for gorse which triggered a memory of how the goats used to love the gorse flowers way back when in the west of Ireland.
Which is the sort of thing that sets you Googling!
It seems that the gorse was introduced to New Zealand as fodder for sheep, probably goats as well, on soils that were too poor to support anything else. You tend to think of gorse as too tough and woody – let alone prickly – to be edible at all but if it is managed, the young shoots are less prickly and very nutritious.
“… For furze, writes Lucas, although regarded as little better than a troublesome weed, formerly played a considerable role in the rural economy of large areas of Ireland, first as a hedging plant, much as we now use hawthorn.
In 1835 a travel writer going from New Ross to Enniscorthy found the route uninteresting; and “it would have been entirely bare, had it not been for the gorse or whin hedges of dark green.” Furze was also a crop. If sown thickly the plant does not branch, it throws up long succulent shoots with few or no spines and the scythe can reap it easily.
Enormous claims are made for the number of animals fed from one acre and ten perches. And there is a picture of a machine for cutting the more branchy stuff. Bit like a turnipslicer.” …
The book he is talking about is ‘Furze’ by A.T.Lucas and published by the National Museum of Ireland

Gorse was brought to NZ for some reason or other by settlers. It is prolific in NZ and much vilifiled, sprayed and pulled out by farmers ever since. It is however so prolific it is everywhere in the north island and FANTASTIC for bees. However, I have never heard of it generating a crop of honey. Generally the native bush has not evolved with/for honeybees, so it tends to shut off in winter. Many hives are brought back to town.

Hello Debbie and thank you for your interest!
Here are a couple of questions for you:
Is there gorse in New Zealand and do beekeepers get a crop of honey from Corydyline australis?
