Episode 74: Buzz Pollination and Soapwort

(audio coming soon)

It’s tomato season! Did you know that the flowers of tomatoes are self-pollinating? Fused petals surround the anthers and keep most pollinators from accessing their pollen. However, it doesn’t stop bumblebees. Casey describes how bumblebees perform an act called buzz pollination, which shakes the pollen loose from a tomato flower and allows them to collect and transfer it.

Daniel introduces us to a European plant that has proven useful for making soap, earning it the name soapwort. Its usefulness prompted Europeans to bring it to America, where it has also been planted for its ornamental value. One problem – despite its usefulness, its aggressive and resilient nature makes it a troublesome weed.
