masstika! first of all, how strange is this; in my post about layering, I mentioned a stick of incense that I burn while heating Palo Santo chips, but couldn't recall what it was, because the label is only in kanji... they're the Seijudo Shiragiku (White Chrysanthemum) sticks!!
Wow. What are the chances that you'd mention those? As soon as you wrote White Chrysanthemum, I knew they were the ones.
I totally agree that finding a high quality cherry blossom stick is going to be nearly impossible. I
really wish that weren't the case.
Where can TMC Holy Land powder be found? I'd love to try some. As long as it smells (exactly) like the crushed sticks do, I'll be very happy.
AbuAyoob; My personal favorite Tibetan incense is Tibetan Medical College's "Holy Land".
I also really love Samye Monastery's powder. It's more gourmand, in its spices, than Holy Land, but beautiful and unique (though still clearly "Tibetan"). I bought some Samye sticks last year, and they're not as nice as the powder (which I bought in 2010). Not sure if they've changed their ingredients, like I've heard Highland did. I have some Highland power from a couple years ago. It's wonderful, but I can't recommend that you pick any up, because people are reporting that the new stock is a mere shadow of what the older stuff was.
Essence of the Ages has a good selection of Tibetan incence:
