Perennial Veg?

That's OK then, Danny.
These plants cost real money to buy and take time to establish themselves. They're not a quick fix but for the long term. I've seen too many disappointed people who think they are a magic solution - plant these and you'll never have to buy another plant/packet of seed or work your plot again.
Fruit bushes and trees, perennial herbs and rhubarb, kale, maybe asparagus, are the perennials that I think are worth growing. I've tried many other "perennial" veg but most of them I wouldn't bother with again.

If I can last as long as a 5 year perennial I'll be happy Veggie.

I agree regards Rhubarb, Kale, and Asparagus and also intend to give 3 - 4 more a go
