My father used to day "Any fool can grow vegetables, it takes experience
and skill to have fresh veg all year round and not lots of excesses."
As I have difficulty growing some veg I guess that puts me in my place.

Two of several vegetables which can be cropped fresh all year round are
leaf beet( perpetual spinach) and curly kale. They are grown as annuals,
but plants from one year's spring sowing will crop on until the next
year's sowing are ready to be picked. We are never without them.
