Why Choose Purple Ornamental Grass?

Purple ornamental grass stands out for its alluring colour and adaptability. Unlike traditional green grasses, purple varieties introduce extraordinary contrast that enhances surrounding plants and hardscapes. These grasses are also known for their resilience – most thrive in a range of conditions, from full sun to partial shade, and tolerate dry spells once established.

With its unique colouring, purple ornamental grass can:

Serve as a focal point in borders and gardens
Provide colour through summer and autumn seasons
Complement silver, gold, or green foliage
Enhance garden design with texture and movement

Top Purple Ornamental Grasses for New Zealand Gardens

Several beautiful species suit local conditions. One standout is the Liriope 'Royal Purple', an evergreen ground cover with lush, purple-tinted leaves and vibrant violet flower spikes. Its low-growing form is perfect for edging paths or planting beneath trees, making it a favourite for both shade and sun gardens.

Another option to consider is the Miscanthus Gracillimus, renowned for its elegant, arching foliage and striking plumes. While not fully purple, Miscanthus brings a subtle reddish-purple tint as the seasons change, adding depth and beauty to mixed plantings.

Complementary Plants to Enhance Purple Grasses

Purple ornamental grass pairs well with a variety of plants. For vivid contrasts and layered colour, try integrating these:

Acaena purpurea (Piripiri): This NZ native ground cover displays soft reddish-purple hues and interesting texture, making it ideal beneath purple grasses or in mixed beds.
Dodonaea viscosa purpurea (Purple Hop Bush): With glossy, vibrant foliage, this shrub brings rich purple tones that complement ornamental grass selections.
Calamagrostis 'Overdam': While predominantly variegated, its foliage offers a cool, creamy backdrop to show off purple hues nearby.

Tips for Growing Purple Ornamental Grass

Most purple ornamental grasses are easy-care once established. They prefer well-drained soil and regular watering until settled. Mulching helps retain moisture and suppress weeds. Fertilise lightly in spring to encourage healthy growth and vivid colour. Prune back older foliage as needed to keep the plant neat and vibrant.
