ANOTHER Weed?

       Technically - yes.  An Oenathera (Another I had to Teach the Spill-Chucker) AKA Evening Primrose.  One of these nights I'll have to sneak out and sniff it; I'm led to believe they are scented, NOT that I've ever smelt one.  Then again Alice could smell a Box Plant (Buxus sempervirens) at 5m when I have to stick my nose into the Hedge to smell anything.
       Weed?  Like I said technically; it was last seen about 10yds/metres away in a Border which disappeared over a decade ago.
