I love peas. After 6 years of selection starting with English garden peas, I have a landrace that will grow during our summer (upto 45C).
They take 40 days from seed to eating and taste fantastic. But germination rate is about 50% & I only get a handful of pods per plant, before the plant just stops flowering, wilts, and dies. And they need a fair bit of water.
Leguminous tree Leucaena Leucocephala grows easily as long as it gets some help with irrigation in its first year. I've got this vision of having a tree with thousands of garden pea pods growing on it, producing all year round for many years in a row. I know you can graft peas onto beans and vice versa, so could it be possible to graft them onto a leguminous tree? Some googling hasn't returned any evidence either way. Is this a fantasy or should I pursue it. Don't just say "give it a go and you'll find out" because with no grafting experience I will not know if failure is due to it being a non starter idea, or if it's simply down to bad grafting skills.
