I did try to search but didn't find what i was looking for - I'm sure that's my fault as this must have been discussed many times.
I'd like a list of perennial garden vegetables, and to hear about folks' experiences with them.
Briefly about our place: we have about 4.5 acres up in the Welsh hills, the soil is very rocky and not fertile, we have 1.5 acres of grazing meadow, currently no grazing animals, are setting up a conventional fruit orchard and hopefully also an experimental food forest area along with firewood copses (alder and willow). And then we have the 'kitchen garden' where I hope to grow lots of veggies! 'Field vegetables' - ie potatoes definitely and then possibly other things - are in part of the meadow, so the kitchen garden is for stuff that needs more attention and is used more frequently. This is our first year on the land and I currently have three small raised beds and two large planting areas which have cabbages, caulis, assorted zuchinni and squash, peas, fava beans, climbing beans, salad stuff, jerusalem artichokes, and some others. The strawberries are there but will be moving, so currently th only perennials are the jerusalem artichokes. I'm also building another large bed/planting area which will be ready next spring.
I am thinking of planting some dwarf cherry trees, and globe artichokes. I also definitely want to plant lovage and more wild/perennial salad stuff like poached egg plant.
I have heard that runner beans can be grown as perennials in this climate, would love to hear if anyone has done this. I have previously failed with the perennial 9-star broccoli, but I could try again. I'm trying to establish a local variety of wild cabbage that, while not actually perennial, once established self-propogates well and if it takes would keep us well-supplied.
And I'd like a list/more suggestions of perennial veg to try. Fruit, as I said, is already in progress

Thank you in advance for any hints!
