Rajan, another beauty; I have a Laburnum in the garden, probably a distance cousin of the Indian Laburnum, it produces large long clusters of gorgeous yellow flowers, no fruit so far :). I also remember larger trees in the Caribbean with the large bean-like fruits but I did not know the pulp were edible.

Thank you for this great info.
