Beware the Bidens! Kelly and I were naive when it came to this common plant. It looked innocuous so we let a few grow. We’ve never seen it before in our yard and had to post a picture to Facebook’s only useful group, Plant Identification, in order to identify it.
Bidens is in the Asteraceae family which includes sunflowers, daisies and asters. There are many different varieties of Bidens and an equal number of popular names, according to Wikipedia: “beggarticks, black jack, burr marigolds, cobbler’s pegs, Spanish needles, stickseeds, tickseeds and tickseed sunflowers.”
Those popular names should give some clues as to the plant’s behavior. Brush up against it and this happens:
It turns out that nature has brilliantly designed these seeds to hitch a ride on mammals. Just touch or lightly brush up against the seed pods, which resemble mid-century chandeliers, and you’ll be picking out seeds for the next hour. Plants can’t move on their own so they’ve got to enlist helpers. In the case of Bidens, we’re the Uber.
Do you have Bidens in your garden?
