Please note that most often you won't be able to get a wholesale discount from a lot of vendors unless you have a valid tax ID.
The following companies sell flowering teas- Adagio.com, Numi Teas, Teaposy. Teaposy is ridiculously expensive, but there is a wider variety. Numi sells their flowering teas loose- so each bloom is sold in various quantities for various prices ( I saw one that stated 65 dollars for 38 pieces, so about $1.70 per bloom). Adagio teas have boxes of blooms, individually wrapped, 10 to a box for $10.00.
I think it's very sweet that you and fiance met in a tea aisle! I'm hoping that this information helps! I would also suggest check out an Asian Grocery/Chinatowns, etc in your area (if any) to see if they have any bulk tea sections.
