When I traveled the Peruvian Amazon region five years ago, I found the sweet Guabilla bean in a local market and took some seeds to Thailand. My tallest Guabilla tree (Inga marginata) is now about seven or eight meters high in Pattaya, another one is in Nong Khai, close to Laos. We have now Guabilla trees for sale in Thailand and Laos.
The white stuff around the beans of the Inga marginata is edible and very popular in South and Central America where it originated. It is also called Ice cream bean.
I took some of those Inga marginata seeds back to Thailand and properly planted them.
My Guabilla tree grew quite fast and flowered twice already, but unfortunately we could not harvest any fruits yet. Therefore we had no seeds available for propagation in Thailand or Laos. On my latest trip to Colombia I found some seeds of Inga marginata, brought them back to Thailand, planted them, but a squirrel must have eaten them.
It took only a few weeks to air layer our large Inga marginata branches.
The branch of the Inga marginata tree is then potted and we have gained an identical plant or clone.
We have just made six more Inga marginata trees which are for sale in Thailand or Laos. The advantage of this method of propagation: You get tall, mature new Inga marginata trees that can bear fruits immediately and beautify your whole garden with their beautiful leaves as well.
