My fave jasmine fragrance is Olene by Diptyque. As for tea, the list is swelling:
The bugari ones (green and white) are awesome.
Duel by Annick Goutal is hands down killer.
Green Tea by Roger & Gallet is even better than the Bulgaris.
Silver Mountain Water by Creed is one great black tea fragrance.
And last but not least, HAMPTON'S by BOND No. 9 is my ultimate tea fragrance. Don't look for Hampton's because it's still not released, but *I* have it
