A bit of scientific frivolity -- Thirsty Plants Text For Help

I ran across this tidbit on a science site that often features research on plants and their interactions with the natural world. Maybe someone will take this principle farther for large outside containers or even garden soil:

Interactive Telecommunications Researchers Develop A Device For Plants To Send Text Messages
January 1, 2009 Â Interactive telecommunications researchers designed a soil-moisture sensor device that can allow a house plant to communicate with its owner. The device can send short messages to a mobile phone or, by using a service called Twitter, it can send short messages to the Internet. The messages can range from reminders to water the plant, a thank you or a warning that you over- or under-watered it. To communicate, probes in the soil emit electric waves. A voltage level based on the moisture content is sent through two wires to a circuit board that compares the optimum moisture level with the current one. A local network receives this data and allows the plant to send a message through the device.
