Yes The one I bought from tea house is I think jasmine tea. although its leaf is dark in color

I think it is not jasmine tea, because jasmine is in white color. It is a kind of flower tea and the purple flower is a kind of chrysanthemum. This type is popular now and favored by the female bacause they have different function of of eliminating toxin, beautifying skin. It taste sweet because added with rock candy, I think.

if you see that a flower poped open, it really has no name we just call it flower tea...
