When I'm working on the nursery I get asked about this humble weed that we allow to remain in a few spots in the garden, almost more than any other plant. I do love it, but I also think its crime to hear about Sarah raven charges money for it....as an act of rebellion i usually remove some of its copious seeds and put them in my customers hands for nothing they always leave with a smile. so I vow to have this beautiful weed in my garden.
