Camellia sinensis comes in two major natural varieties, C. sinensis v. sinensis and C. sinensis v. assamica. Other natural varieties (that I didn’t even know about before looking into it just now) are v. pubilimba, v. dehungensis, and v. madoensis. The related species Camelliia taliensis is also used to make tea, especially pu-erh.
In addition to these natural varieties, there is a huge variety of cultivars. And the terroir makes a difference. But I think that tea drinkers by and large like their tea to taste like tea.
tl;dr Camellia sinensis has both natural and bred varietals.
I like it. I visit classical concerts more than pop ones, but there it definitely isn’t automatic, but a light-hearted “artist’s choice” response to a genuinely enthusiastic crowd after the approx. 3rd round of applause. Not a given. My favourite is still when the soloist did a jazz encore and the audience swapped from “no applause even between movements” classical mode to “applaud good solos” jazz mode.
