Panicum amarum is a native warm season grass prized for its ability to stabilize sandy soils and provide architectural structure to coastal and prairie landscapes. Its upright blue green foliage turns golden in fall and airy seed heads appear in late summer offering movement and texture. Drought and salt tolerant once established, it is a key species for erosion control and supports local wildlife.
Height & Spread: 36 - 60 in x 24 - 36 in
Bloom Time: Late summer to fall
Light Requirements: Full sun
Soil Preference: Tolerates sandy, poor, or dry soils; excellent drainage preferred
Watering Needs: Low once established
Deer Resistance: Not preferred by deer due to coarse texture and tough foliage
Native Status
Native to North America, especially coastal plains and sandy habitats of the southeastern United States. It plays a crucial role in native ecosystem stability and restoration plantings.
WILDLIFE & INSECTS
Birds
- The airy seed heads attract sparrows, finches, and bobwhites who feed on the seeds through fall and winter.
Beneficial Insects
- Provides habitat and cover for predatory ground beetles, spiders, and overwintering pollinators such as solitary bees.
Spacing & Landscape Use
Spacing Recommendations:
- Space 24 - 36 in apart to accommodate full mature width and allow air circulation.
Landscape Placement:
- Ideal for coastal dunes, prairie plantings, large sunny slopes, and rain gardens. Acts as a vertical anchor among flowering natives and other ornamental grasses.
Companion Plants
- Asclepias tuberosa (Butterfly Weed) - Orange blooms and sturdy habit complement the grass’s upright form in sunny habitats.
- Rudbeckia hirta (Black-eyed Susan) - Bright golden petals provide seasonal contrast against the soft grasses.
- Echinacea purpurea 'Magnus' - Broad flowers and sturdy stems mirror the resilience and bold texture of Panicum.
- Solidago rugosa 'Fireworks' - Explosive yellow blooms blend well with Panicum’s fall coloration.
- Liatris spicata 'Kobold' - Dense purple spikes echo the vertical rhythm of Panicum while attracting pollinators.
