I love my perennial kales! I planted perennial rocket seeds this year but was told you can grow them perennially anyway.
Chillis last for years as long as there is enough temperature.
Other plants are like perennials in that you don't have to plant them each year because they just seed themselves lol!
eg Aztec broccoli, magentaspreen etc
That is besides berries and fruit and nut trees ...
I feel that as much perennial as possible gives you a buffer of production and more time = more security of crop
Plus the benefits of no dig!
