From “Heavy Metal” Plants to Plant Clocks. A common theme for the most popular plant news stories from my February, 2017 HPW Twitter feed appears to be evolution – from the genes involved in the evolution of parasitic plants to common evolutionary traits of carnivorous plants. And the most popular…
Happy New Year! And the Winners Are…. For the past five years, I’ve started the new year here at the How Plants Work blog by taking a look back at the previous year’s plant-related news from my HPW Twitter feed and sharing a few of the “tastier” tidbits, month-by-month. This…

(If you’re interested in such metaphysical aspects of plant physiology, please see here, for example.) What I’m referring to is the notion…
When No Really Means No (In Plants) When it comes to sexual reproduction, nearly half of all flowering plant species are self-incompatible. That is, the pollen (male parts of flowers) produced by an individual plant is somehow recognized by the plant and rendered ineffectual in self-fertilizing the ovules (female parts…
A recent story about how some of our Washington state lawmakers hate the sight of dandelions reminded me that it’s time for an encore of this post. Hope you enjoy it….again? Dandelions – Much Maligned. Some people become upset when they see dandelions (please see here, for example). Few plants…
