This beautiful, warm season ornamental grass has metallic-blue foliage and a columnar form. The flower panicles with a slight pinkish tinge could bring the plant to a 6’ height when in bloom and form a visual cloud at the top. The foliage turns yellow in autumn and a tan-beige in winter. Plant these as an accent, group, mass, or as a small screen. These work in water or bog gardens and along pond edges.

Planting Care

Planting & Care for Heavy Metal Switchgrass

Preparation
  • Heavy Metal Switchgrass is an outstanding selection of Panicum.
  • The loose and open panicles (pyramidal shaped seed heads) appear in August or September, and remain attractive all winter.
  • The fall foliage is a tan-beige color, which looks beautiful in the landscape.
  • Mature height of 3-4' is common if grown in a sunny, well drained site.
  • This ornamental grass can be used in mass or as a specimen in the landscape.
  • Hardiness zone 5.
Opening Plant Material
  • Container - Completely saturate all container plants by putting in a larger container of water until stops bubbling, then remove the plant from the container. 
Planting Container
  • Dig a hole no deeper than the depth of the container and 6" or more wider on the sides.
  • Slide plant from pot by tapping on the bottom of the pot.
  • With shovel or knife trim bottom 2" off of the root ball for plants in plastic containers.
  • Rotate the plant to the proper position. Never lift or move plants by the tops.
  • Place the root ball in the hole.
  • Adjust the plant height so the root crown is slightly higher than the ground.
  • Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer
  • Back-fill the hole with soil, making sure the top of the root ball is visible and slightly higher than the soil around it.
  • Firm the soil around the plant. Water well to settle soil around the root ball.
  • Water frequently when newly planted. 
Pruning - After Planting
  • Container - Although it is not essential for container plants to be pruned after planting, a light pruning to remove any broken branches during shipment and improve shape will help the looks of your new planting.
Pruning - Through-out the Season
  • Cut back late in March if possible before new growth begins.
  • See our instructional video on pruning ornamental grasses in the landscape on our “videos” tab.
 Watering - After Planting
  • Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as oft en as every 2-4 days at the start and at least a minimum of once per week.
  • Beyond the 6 week establishment period, water once per week, unless rains occur.
Watering - Through-out the Season
  • After the first season, plants should only be watered during extended periods without rain.
  • How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it is dry, give it a good soaking with the hose end (no nozzle) watering the soil only, not the leaves.
