The award this year goes to…
Ok, I chose this partly because of its name, so very topical this year! If there had been a Covid 19 weed, I might have chosen that instead. As it was, it was a toss up between Bidens pilosa and lantana camara, both of which plague me to death. This year we had a massive lantana clearance drive, and they’re already creeping back. But lantana we have always with us, while Bidens has burst upon us suddenly this year.
This Bidens has pretty daisy-like flowers, very like the cute Tridax Daisy, the one whose heads we would flick off as kids. Both are natives of the Americas. But the leaves of Bidens are more angular, darker, more sinister looking, and it has sharp, pointy so-called seeds (thorns is as thorns does) that pierce through your clothes and stick into your tender (and awkward) places for months afterwards, driving you mad. It’s very invasive, and has run amok in all my beds in the past year.
Take note: Mr. Biden is welcome, but Bidens pilosa is definitely not!
