Mānuka honey known for being is earthier, richer, and more viscous than many other honeys. It comes from the nectar of the flower of Leptospermum scoparium — also known as Manuka, which is only native to New Zealand. Mānuka, in fact, is a Maori word.

“The plant itself is very rare. It’s difficult to harvest because the flower is only open for 12 days, and sometimes we have to use helicopters to collect this honey.” John Rawcliffe from the Mānuka Factor Honey Association told Business Insider.

Although mānuka bushes can also be found in Australia, New Zealand accounts for almost all the world’s production, with exports worth 300 million NZ dollars ($204m) and expected to rise to 1.2 billion NZ ($800m) by 2028.
