Mike - I saw you mentioned Indonesia.
But are they grown on the mountains in Indonesia?
Maybe i shouldn't call them ultra-tropical lychee's (or lynchee as they call them here) but i would like to know which other lychee i can grow here in Bangkok. Big ones would be great but any lychee is welcome as long as i can get them to fruit.
On the pic's they don't look very big, i remember they were bigger when we visited the area where they grow. That was not in the mountains.
The Amphawa lychee's are not hard to get but mostly they don't reach Bangkok in big quantity's.. I guess the locals like them as well
. They can be bought around Thai New year (Songkran) which is around mid April. That's the most hot time of the year.
I have never heard of grafting it on rambutan, my neighbour is home today and he is a proffessor in botany. I will ask him which lychee can grow here. He told me about when the Chinese arrived (in the past) and they also could grow lychee's in Bangkok.
