I am a tea drinker - its part of my Aussie heritage! So I have been drinking teas of all sorts for 50 years...and always thought that the different forms of tea (white, green and black), came from different plants! Last week I was in Hawaii for work (tough gig I know) and toured a tea growing farm and learned A LOT about tea.
So here is the basics - white (sometimes called silver needle), green and black tea all come form the same plant! It all depends on how many and what type of leaf is picked!
