A Plant Needs Its Mother

…Plants grown in the same setting as their maternal plant performed almost 3½ times better than those raised in a different environment — indicating that maternal plants give cues to their offspring that help them adapt to their environmental conditions.

How Green IS your green roof?

Stephan Brenneisen, a Swiss green roof specialist and ecologist, claims that many of the thin substrates on sedum roofs lose their effectiveness over time… [he] also found that many sedum roofs have minimal positive effects on storm water retention, energy use, or the urban climate — core arguments that have been used to justify the implementation of green roofs. Moreover, ecologists attribute rather limited biodiversity values to sedum roofs and prefer roofs that offer a secondary ha

Plant Extinctions Leave Permanent Gaps

The results showed that ecosystems with fewer plant species produced up to 50 percent less plant biomass than those with more natural levels of plant diversity. You might think extinctions would just mean other plants would take over and fill in the gaps, but that is not the case, the scientists found.

Testing Botanical Intelligence

If you define intelligence as the capacity to solve problems, plants have a lot to teach us… Not only are they 'smart' in how they grow, adapt and thrive, they do it without neuroses. Intelligence isn't only about having a brain.

Invasive Plants Have An Edge

We’ve seen this capability in a number of invasive plants that have come from Eurasia, such as garlic mustard… The roots exude a toxin that kills native plants.

Insects Manipulated By Plants For Sex

The plants heat up and emit a toxic odor to drive pollen-covered insects out of male cycad cones, and then use a milder odor to draw the bugs into female cones so the plants are pollinated.
