Someone of another Ng has posted a photo of a weed we used to have on a
previous allotment, but do you think I can remember the name!!!
Perennial, too deep rooted to dig out, reddish roots ( we called it Red
Root), hairy/spiny stem to 2 metres, leaves alternate with spines underneath
on the midrib. Possibly with yellow flowers but we never let it flower.
