PSB - experiment!

I have another PSB experiment for this year!! You may recall that I've been given 2 trays of seedlings - labelled Purple Sprouting broccoli and Green Sprouting Calabrese. There are lots of both. 



I read, in one of Vinny's posts, that 4 plants are enough for him, which means I must have at least 40 plants that are too many. At the moment, I'm thinking of planting them, randomly, around the garden, in the hope that some will not be spotted by the "One eyed, one horned, flying purple broccoli eaters" (for those of you old enough to remember the song).
What are the chances of growing a PSB Forest or will it be some useless stumps? What do you think?

Been there done that!  I had a potager type allotment once where I developed 'pocket' planting into the regimental  beds.Each bed had the same stuff in it, a PSB,a soft fruit bush, onions,leeks,carrots,beetroot,flowers etc etc etc.
I think they have a fancy name for it now "summat culture".  My long narrow beds now are planted up with blocks of various veg & flowers which are I suppose elongated pockets?

By growing more PSB plants than you need I would imagine you and the chooks would soon get sick of them!
