Panicum 'Heavy Metal'

Panicum 'Heavy Metal': Metallic Blue Posture From Spring to Snow

Stiff, metallic blue-grey blades standing bolt upright like they've got a mosh pit to get to. 'Heavy Metal' does not sway politely in the breeze. THIS GRASS OWNS A BAND T-SHIRT.

• Features: Fall and winter interest, RHS Award of Garden Merit

Where to Plant: Its strict, upright shape makes it a vertical accent in a sunny border, a soft screen in a row or a tidy specimen in a large container. It copes with clay and sandy soils and tolerates some road salt, so it's a sensible pick near driveways and sidewalks.

Companion Plants: Use the metallic blue blades of 'Heavy Metal' behind a sunny, dry bed of soft pink and blue. Sempervivum 'Red Beauty' tucks in at the front at 8 to 10 cm with deep pink summer flowers. Armeria Dreameria® 'Daydream' adds soft pink globes at 25 to 30 cm from May to September. Salvia 'Blue Hill' brings clear violet-blue spikes at 45 to 60 cm from June to September. Nepeta 'Walker's Low' adds lavender-blue spikes at 60 to 90 cm from June to September.

Plant Care: Plant in full sun in average, well-drained soil. Once established it handles both dry spells and the odd wet patch. Skip the fertilizer, because rich soil makes switch grass softer and more likely to lean. Water regularly through its first season. Leave the foliage up through winter. Cut the clump back to about 10 cm (4 in) in early spring, before new growth starts. Switch grass is a warm-season grass, so it wakes up late. Don't give up on it in May. Divide in spring every few years if the centre starts to thin out.

History: 'Heavy Metal' is one of the oldest named selections of switch grass, a defining grass of the North American tallgrass prairie. It was introduced by Maryland nurseryman Kurt Bluemel in the 1980s and holds the Royal Horticultural Society's Award of Garden Merit.

Final Thoughts: Low maintenance, deer resistant and still headbanging through the winter. Plant three and call it a REUNION TOUR.
