Here in the U.S., nearly all the information we have on Pahari Kela comes from Dr. Chiranjit Parmar -- a colleague of
Julia Morton. He resides in northern India and distributes a CD on edible plants which you can view on his website:
Fruitipedia. It is from Dr. Parmar that I learned of Carissa spinarum - a plant I now grow here in San Diego. Dr. Parmar does distribute plants too, but he does not have access to phytosanitary certification. Consequently any plants (and seeds in my experience) that he ships to the U.S. are rejected by Customs. In particular, I received my Carissa spinarum from the Tropical Agricultural Station in Puerto Rico. In the past decade, some members here in Europe -- particularly eastern Europe were able to obtain Pahari Kela from Dr. Parmar but it has been years since those members have posted on Bananas.org.
