Tastier leaves? Could be? The colors of seed to reflect different chemical realities in the plants it seems; I know I've read that white colored bean seeds have less antibiotic properties/resistance to pathogens that other colors. Maybe there are other co-relations that only critters detect.
Well, I generally assume white seeds and white flowers often (though not always) indicate lower amounts of those anti-pest compounds that make the seeds less tasty/more toxic. That was one of the reasons I was interested in trying to grow white seeded horse gram; it seemed to be one of the few legume crops where white was possible but had not already become the industry standard. I'd like to do the same for the wing bean, but it seems that, there, light tan/cream seems to be the best one can do, same as with soybeans.
Wow, your coriander formed seeds already! My goodness, you & I really do have different growing conditions! I only put my seeds in the ground this afternoon!

To be fair I guess, I could have planted them awhile ago, the weather has been very good these last few weeks.
Well, you have to remember I planted mine indoors at least a month ago. The plant was already fully bolted, flowering and forming seeds before I even brought it outside. Plus different varieties mature at different rates (if there is a slo-bolt, there are presumably ones that bolt faster than normal as well.) Remember I just picked this founding seed out of a bag, I have no idea what kind it is.
There are now a fair number of pods on the fava. Some would be almost full size if I was growing small fava beans (the "horse bean" type they like in parts of the Mediterranean,) but I know I planted full size, so they have a LOT more growing to do.
Oddly, no sign yet of growth in the purple pincushion pot. Maybe I held the seed too long. If I did, at least I can be comforted to know that the fact that still sometimes shows up in the coriander means I can get fresh supplies if I am patient. Maybe I'll check the others next year, while there is still a chance some of them are good (though, to be honest, if the glue thistle seed DID prove to be dead, I wouldn't feel all that bad. Finding out what it was was fun, but I can't honestly say it's something I feel a deep need to grow again. There are plenty of other thistle like flowers with bigger blooms, and THEY don't leave my hands sticky when it's time to harvest seeds.)
