It has already been over a month since I received this cute photo in an e-mail from my boyfriend, saying that this is all that he grew this year and that if groceries were up to him, we would starve... He also mentioned that he wanted to take a picture of his hand holding it, but it looked "far too sad".
I think that - for a beginner - he did quite nicely. We will definitely try to grow some more next summer and maybe with a bit of supervision, he can become a really awesome gardener :)
By the way, I am thinking about growing lentils (not sure whether in out mid-European climate or on some adopted piece of garden on the British Isles yet), so if anyone has any advice, ideas or useful links about lentils, please do let me know, I will be very thankful.
