This plant has sleek, narrow, blue-green leaves with red and yellow margins, and is armed with needle-sharp points. Locate this plant away from pedestrian traffic but close enough for folks to admire the color and symmetrical, rosette form. This hybrid grows to about 1 to 1.5 feet high and 2 to 3 feet wide. Provide with afternoon shade in low desert climates. Leaves “glow” when backlit by the sun, thus its name. The canopy coverage is 7 square feet.
