Anyone know much about Purple Durban?

I have some seeds from a supposed bag of Purple Durban, but seems like there is very little info on the strain out there. I hear it's sativa and that's pretty much it. More info for the Durban Poison, but not sure if it's hybrid or what.

The bag i got smokes great and is very stony, it just had a few seeds in it... found 7 so far.

I actually asked for a bag with seeds from my dispensary, kind of a funny moment.

So i was back at the same dispensary today and didn't see Purple Durban, but Durban Poison... I asked the guy and he said it was the same.

So got about 13 seeds now that i'm not sure if are really Purple Durban or Durban Poison... i hear Durban Poison is one of best Sativas to grow.

Again, not much info on Purple Durban so when i grow these seeds i guess i'm gonna call it Durban Poison when i grow untill i'm proved wrong or something.
