Raleigh-based writer Patrick Jonsson had an interesting piece last week in The Christian Science Monitor about new research, some of it at NC State University, probing the concept of ?intelligence? among plants.

I know, it sounds absurd, but the argument isn?t really that plants are conscious and sentient but that they exhibit some of the classic definitions of intelligence:

Hardly articulate, the tiny strangleweed, a pale parasitic plant, can sense the presence of friends, foes, and food, and make adroit decisions on how to approach them.

Mustard weed, a common plant with a six-week life cycle, can’t find its way in the world if its root-tip statolith – a starchy “brain” that communicates with the rest of the plant – is cut off.

The ground-hugging mayapple plans its growth two years into the future, based on computations of weather patterns. And many who visit the redwoods of the Northwest come away awed by the trees’ survival for millenniums – a journey that, for some trees, precedes the Parthenon.

As trowel-wielding scientists dig up a trove of new findings, even those skeptical of the evolving paradigm of “plant intelligence” acknowledge that, down to the simplest magnolia or fern, flora have the smarts of the forest. Some scientists say they carefully consider their environment, speculate on the future, conquer territory and enemies, and are often capable of forethought – revelations that could affect everyone from gardeners to philosophers.

Indeed, extraordinary new findings on how plants investigate and respond to their environments are part of a sprouting debate over the nature of intelligence itself.

The whole piece is worth a read.
