Wild Plants as a Food Source

[Devonian]

Now this might seem a little strange and is only something that I have recently been thinking about, but has anyone ever given consideration to purposely planting/seeding wild plants which are known as a good food source??

I was thinking about things like Dandelions; Burdock; Sorrel.......

The idea would then be to spread the seeds around local hedgerows; wasteland; protected edges of fields etc etc, basically anywhere close to your home or BOL where they could grow freely during normal times without being damaged/cut down on a regular basis. This would then mean you have a well established natural larder in place if ever needed as these plants will largely just keep growing year after year and will also reseed providing an increasing number of plants over the years.

The great thing then is that if your main garden is ever raided and cleared by your hungry neighbours or others, you have a back source which is likely to be overlooked by most people, even if they are walking straight past it!

A quick look on amazon shows many of these seeds are available to buy and are very cheap:

So has anyone else considered this and if so, what would or have you planted?
