Typically, we gardeners don't think of our favorite activity as something likely to make the nightly news. But we'd be wrong. Frequently, a number of environmental issues connected to plants hit the headlines. And this week so have some lighter garden-related stories that may make you smile. (Anyone for growing asparagus on Mars?)

I like to keep up with the environmental news as it relates to plants. And the best way to do that, I've found, is to read Science Daily.

The clear winner? An old favorite, blue flag iris. Other top performers included eastern gama grass and big blue stem.

The article reports: "Researchers at the Missouri Tree Ring Laboratory in the Department of Forestry discovered that trees submerged in freshwater aquatic systems store carbon for thousands of years, a significantly longer period of time than trees that fall in a forest, thus keeping carbon out of the atmosphere."

Everyone loves towering old trees. And what a delight to learn that all along they've been environmental do-gooders and keeping it a secret from us.

Since I've been following the issue of weeds and climate change, I took note of one more study on the subject: Elevated Carbon Dioxide Boosts Invasive Nutsedge Plants. The title says it all.
