Perennial Vegetable Garden

[ElderflowerTonic]

I have a fenced off part of my garden that I use for growing vegetables. However the last few years I've been working more hours so I have less time for it. Also the early dry spells this year and last year meant that a lot of things didn't grow well at all.
I want to make the patch simultaneously less work and more productive. I'm going to put in rows of asparagus, rhubarb, chives and strawberries. I'm still going to grow onions and lettuce as they always do OK. Any other ideas for plants would be much appreciated.

I think two other low maintenance options would be Kale (few pests vs other brassicas) & spinach

What about fruit bushes (raspberries, currants) if you have space?

Cut and come again salads from RHS

Both Globe artichokes and Jerusalem artichokes grow well year on year - great sculptural foliage on the globes, and lovely late summer flowers on the Jerusalems.

We have a couple of lines of sorrel to add into salads and love it. One is the French variety and one giant Russian and both going strong several years on.

Tree cabbage - should grow for a few years.

Chard isn’t perennial but is low maintenance. Doesn’t mind when it’s picked and you can still pick after it’s bolted. Currants are easy to ignore too.
