I grew them in my Vegie plot using Azolla as a fertiliser. See
The thread "Azolla - growing and using" in
Ponds and Water Gardening forum
They did very well. ate off the plants for around five weeks.
Over the past week or so have been collecting seed for next years crop. Had marked the plants which tillered early and frequently. The reasoning being the more tillers, the more flowers and hopefully Beans.
Noticed there were some of the marked plants, had started to produce new shoots with two of them having a flower each despite the new shoots being very small.
Intend to dig up those plants once the seed has been collected and relocate them to an area where they won't be in the way of other vegies I want to grow.
Has anyone done something similar, have success in the transplantation?
Cheers
