The Story
Plant Bio
Sorghastrum nutans, or Indiangrass, is a dominant species of the North American tallgrass prairie. It is a warm-season, clump-forming grass with upright foliage and distinctive, feathery flower panicles. 'Indian Steel' is a cultivar selected for its striking metallic-blue foliage and strong, upright habit that resists flopping. In fall, the foliage turns a beautiful golden-yellow to orange, and it produces large, coppery-gold flower plumes.

Planting
How to Grow
- Plant in full sun in average to poor, well-drained soil.
- This grass thrives in conditions that mimic its native prairie habitat.
- Dig a hole slightly larger than the pot.
- Place the plant in the hole, backfill, and water in.
- Water periodically during the first year; it is drought tolerant once established.
- Cut back to the ground in late winter or early spring.
Pro Tip
Avoid overly rich soils and excessive fertilization, which can cause this upright grass to become leggy and flop over.

Care Guide
Do
- Provide at least 6 hours of direct sun for strong stems.
- Plant in lean soil for the best upright habit.
- Allow it to self-sow a bit to create a naturalistic drift.
- Leave standing through winter for interest and wildlife value.
Don't
- Do not plant in shade, which causes weak, floppy growth.
- Do not overwater or fertilize.
- Avoid planting in overly rich, amended garden soil.
- Do not divide too frequently; it resents disturbance.
