All digital cameras contain an IR (Infrared) filter in front of the chip, be they CCD or CMOS. By having the IR filter removed, the naturally occurring infrared produced by vegetation emerges. (A custom white balance is required to restore the color balance of non-IR emitting objects, such as the rocks in the background. I'm still working on that.)
Some astronomical objects, such as emission nebulae, also emit Hydrogen Alpha (Ha) and an IR modified camera picks up that signal more so than a standard camera. The photo on the right shows what the plant should look like, appropriately named a Blue Agave. Tequila anyone?
