USA tea preferences?

[Tara0]

I'm a UK host and 90% of my guests are from USA. I'm looking for opinions from USA hosts, as to what sort of tea you / your US guests prefer. 

I've always supplied tea bags as a kitchen basic, but I'm about to upgrade  my offering from a few boxes of various tea bags to a selection of individually wrapped 'posher' ones in a single container. It also means I'll be able to provide a little more choice, and it'll look neater on the open shelf where the tea and coffee stuff is stored. 

Over the years, I've noticed that the fruity herbal / camomile / peppermint teas are fairly popular. The strong black teas that we love in the UK are less popular (e.g. English Breakfast). Sometimes a guest will leave behind decaf black tea bags which they bought, but that's rare. So I wonder whether I should swap Assam / English Breakfast tea to a weaker one such as Darjeeling or Ceylon? Or even Lapsang Souchong. And what about green teas?

Basically, I'm ignorant of USA tea culture and some pointers would be really helpful.

We do have a tea culture  but for the U.S. we tend to  be coffee addicts. lol  Maybe if there is tea unique to your area?  In Hawaii we had a lot of Asian tourists so more teas and we would offer like Hawaiian Macadamia Nut or Hawaii Passion Fruit teas things not easily available to them so added to their tropical island experience.
