I have been saving seed from a tall pole pea variety (Alderman) for many years now and they seem to be adapting to our growing conditions. They stay green, healthy, and productive far longer then any other pea we have grown. The one drawback being they don't climb very well, I am forever tending them as they attempt to ascend our pea fence. So this spring we are also growing an afila type bush pea for the first time and were attracted to this particular variety because they are supposed to have few leaves and many grasping tendrils. Imagine, a pea that can actually grab onto a support fence without human intervention. :)
We shall see how they do. I normally opt for pole peas as bush peas seem to develop a myriad of issues in our garden... slugs, rot, etc. The afila peas are supposed to be self supporting but I did set up a short fence for them and they are latching on like crazy. I really don't know much more about them at this point, perhaps they will do really well for us, time will tell.
