Nine Star perennial broccoli

I've grown it before too and it lived for about 5 years - in a netting covered GH. Here's a photo to prove it https://gardenandgossip.org/showthread.p...=nine+star
I don't get on with netting/mesh in the garden. Its always in the way, get blown about and tangled around things it shouldn't.
Thanks for your advice, folks, I'm still thinking!!

I've just checked out your photograph Veggie. Mine were more prostrate than yours and probably half the height? The netting must have caused a micro climate to make them grow upward instead of outward like mine. (Or maybe you just have better weather where you live?) Upside with your method was they were clean heads,whereas mine being close to the ground were quite mud splashed at times.
