I do grow my peas right beside my daylily bed... I mean a foot away! I grow the sugar snap peas. Ordered a new kind this year. "Sugar Sprint" and also the old Mammoth Melting Sugar Snow Pea. I grow them on cow/horse fence made into 2 foot circles and they are right beside the daylilies. I have to keep putting the peas on the fence, or they would be growing up the daylily scapes.
One last comment about how threads wander -- this is actually a thread that I split off of another thread.
I am curious about what other veggies could be put in with daylilies. Mainly early things, unless they were vines put on some sort of trellis or fence.
