...a small proportion of whats there...if the flowers are ready. (I think). Try not to take it all. I was trying to plant some stuff this year deliberatly for people to find! Just the odd plant near car parks and stuff (country). On plant was right by a (ok a very little used woodland car park)...still there at harvest. Other stuff happens that I don't really wanna take about - but try and keep a sense of homour in your response if the landowner on where your weed is growing finds and destroys it.
