The Doi Pui Research Institute in Chiang Mai has launched a project called "Plup Pheu Khun" (Persimmon For You) which involves paying 1,500 baht for a tree to be looked after for a year. When the fruit is ripe, the paying member can visit the institute to collect it, or ask for it to be delivered to their door, according to Wisit Kijsomporn, the head of Doi Pui Research Institute.
