well...
I rumaged around the afore mentioned "far corner" looking for some thing like sandys legs ( poor you sandy to have legs so hairy that they bring people out in a rash
) and took a pick but it was breezy and I couldnt get enough detail in focus.
It dosent look like the ones in the link Daisy but I will explore the site further and see if I can find it.
I think the plant he is reffering to is a narrow stemed plant about 18 inches high. the stems are hairy and cause irritation to the skin. The leaves are a couple of inches long and have smooth edges tapering to a point like a spear head. the shoots growing out from the main stem curve out and up gracefully and at the end of them is a cluster of 4 tiny yellow flowers with 4 petals. It didnt seem to have a distinctive smell.
The pest man said to cut it down to stop it seed ing but I would also like to spray it. Any thoughts?
