Last Friday night I planted up another unusual veg brought from eBay - Chinese artichokes. To be honest I was expecting them to be bigger, like the size of Jerusalem artichokes but these are the size of large grubs! I planted up two raised beds with these and I'll report later in the year how they do.
A good friend of mine accuses me of collecting vegetables like "an American prepper collects guns" - his words not mine!
I think having a large variety of fruit and veg is key to being self sufficient in food. That way you have things to fall back on should crops fail. Something like this is pretty easy to grow as well (so I'm told) needing very little input (like Jerusalem artichokes) but they're there in the ground if you need them over winter, or stored in a frost free place.
Is anyone else expanding their collection of unusual fruit and veg this year?
