Water Saving Tip:

Even though it's hot, your lawn only needs to be watered twice a week to stay healthy.

And don't water the whole lawn for a brown spot—drag out a hose.

  • Description

  • Notes

This switch grass has stiffly erect blades of metallic blue-green during the season, turning yellowish-orange in the fall, and buff in the winter. Tiny purple and orange flowers line wiry stems forming billows of color about grass clump. Grows 36 to 40 inches tall and 30 inches wide. Very attractive when planted in masses.
Panicums are Plains' natives, and they require full sun and well drained soils. Will grow in clay. Over-fertilizing or over-watering will cause the grass to flop. Cut back in late winter, see Guides. No serious pest or disease problems. Though clumping, it may slowly spread by rhizomes, but is not considered invasive. Deer and rabbit resistant.
