Well I don't think there is one. however black lotus is very common I find in worlds like grizzleheim or zafaria. I did around 2 hours of quests in zafaria and picked up reagents while I was doing it. at the end I had about 15 black lotus. hope that helped!
The only vendor is Diego the Dulemaster ; costs 50 arena tickets. I have done these crafting quests myself so I know how hard and how much you need. A good place to get them is in Vestrilund , there's a corner where it has up to 3 every realm switch. You can look up the youtube video for it. Or you can camp out at the bazaar for them, your pick! Good luck :)
I want to thank everyone for their replies. I finally found 4 black lotus in Mooshu (yay). I will continue my search there and try the bazaar. I have know idea where Vestrilund is though..is it in Grizzelheim?
Anyone know what seeds I would need to grow a few through gardening?
Thank you for all of the advice. I ended up staying in a spot where I knew Black Lotus normally appears and I kept changing realms as suggested. It worked. I found 21 Black Lotus in under a half hour. Thank you everybody!!
