Leptospermum scoparium, commonly called mānuka, New Zealand teatree,
or just tea tree, is a species of flowering plant in the myrtle family Myrtaceae, native to New Zealand.
It was called “tea tree” from the practice of making a tea from the leaves
on the expedition of Captain James Cook and the botanist Joseph Banks
when they identified the plant and established its use when their ship, HMS Endeavour,
was moored in Mercury Bay, New Zealand in 1769.
This cultivated plant grows in my garden – the REAL flowers are white.

I just found this comment from man who made a cuppa Tea Tree!!:
Sadly, it tasted like #!*. Way too strong and bitter so I watered it down,
then again and again until it was a colour similar to tap water after all.
While every part of me as screaming for me to enjoy this wonderful natural product of the bush,
my taste buds were telling it to %*&$ off.
