Hi Tanja,
Pigeon pea has been an invaluable pioneer plant for getting my food forest going here in florida, so I’ve planted lots and lots of it here. I started with a black, red, and a white variety, and saved seeds and replanted for a couple years, and a couple of the trees this year have peas that are white with a mottled brownish red color on them, so I don’t know if that means the white and red varieties crossed for those ones. They are the most vigorous trees, out of all the pigeon peas. I am happy to share seeds with you, as I have tons of seeds from it.
