Weird law, weird country, weird BN. (In the Netherlands, seriously?).
I can understand the law, though nothing like it exists (well it's possible that it does, but NO one heeds it) here, but vegetables?! Here it's a *really* common thing to grow vegetables in one's garden, regardless of the area and environment one lives in and regardless of wealth and plot size. This has been the case since WW2, and vegetable growing is actively encouraged. There are also lots of allotments; council owned land that you can lease a plot of (really cheap, but incredibly popular - in London the average waiting time is 30 years) to grow your daily bizzle on. Many people keep chickens on them to, though this is technically a no-no in most places.
It's such a popular, practical and encouraged thing in the UK. I doubt many people would regard it as aesthetically problematic either, the opposite in fact.
For example, in my family homes garden we grow all the basic herbs
we need, apples, pears, plums, tomatoes, strawberrys, black + red currants, plus a greenhouse which has more tomatoes, peppers, chillis, aubergines and sometimes cucumbers in (tomatoes and cucumbers don't grow well together for some reason). We also have three grape vines and a peach tree, though the climate is a bit shit for these.
Then, behind the garden we have an allotment. Potatoes, leeks, onions, runner + broad + green beans, peas, spinach, lettuce, cabbage, sprouts, brocalli (some years), beetroot, radishes, globe artichokes, asparagus, rhubarb, marrows/courgettes, pumpkins (some years), sweet cprn (some years), more herbs, lots more strawberys, currants, gooseberrys, apples, pears and a HUGE raspberry patch (which means we eat raspberrys almost everyday between May and October). Oh and loganberrys too. What we don't grow ourselves, we barter off of other allotment holders. Then below the allotments there are a ton of blackberry brambles and wild fruit trees. To top it all of there are numerous pheasants, rabbits and pigeons, hated by all growers and thus fair game for the table.
We don't really care about 'organic' food (I hate the expression as well), and indeed some of our crops aren't entirely organic (GM experiments baby!), it saves a *lot* of money though over the course of the year. Plus I personally enjoy gardening, so it's eaze.
I'm really surprised at your post BN, would have thought the Netherlands being the densely populated, sensible country that it is would share our roughly nationwide love of vegetable growth.
My family is a bit beyond typical in what we grow (Lincolnshire only really has two industries - farming and tourism), but the country is full of allotment holders from all walks of life who grow as much or more and it's extremely common for people who don't have one to grow vegetables in their back garden (even if that's no more than a balcony!).
Hope this helps.
