The honey flow in Western Australia may just be the largest anyone has seen in nearly half a century.

To the delight of apiarists throughout the region, bees are swarming to forests filled with blooming karri trees, towering eucalyptus giants that can reach heights of up to 260 feet and flower only once every seven to 10 years.

While pockets of the trees generally bloom almost every year, this year's cycle has been noticeably impressive.

"It hasn't flowered like this for 40-odd years or more; nearly 50 years that it's been over the whole forest," beekeeper Mike Spurge told "It's flowering right through the whole 12-month period this year, which it used to do back in the 1960s."

Just how much nectar are honeybees pulling from this rare massive bloom? Beekeepers are reporting that average honey totals from each hive stationed within a karri forest is between 250-440 pounds of honey. For comparison, the best year for the White House honeybee hive was in 2011 with 225 pounds of honey.

"Coupled with the fact the trees flower over such a long period and come out individually, it's all come together to produce a 12-month honey flow essentially," added Spurge.

According to those who have tried karri honey, the amber-colored liquid has a very mild sweetness and is "very addictive."
