Why Planting Steep Banks Matters

New Zealand’s hilly landscapes are picturesque, but they often come with their own set of challenges—erosion, runoff, and difficulty accessing sloped areas. By planting steep banks with hardy, spreading species, you can prevent soil loss, increase biodiversity, and create eye-catching garden features. Groundcover plants are particularly valuable for their root systems, which work to bind soil together and minimise maintenance.

Top Plants for Steep Banks

Choosing tough, resilient plants is key. Native and exotic varieties suited to New Zealand’s conditions can handle challenging slopes and create beautiful, layered foliage.

Aristea major

This striking perennial adds colour and texture to embankments. Aristea major is known for its upright blue flower spikes and robust grass-like foliage. It’s drought-tolerant and thrives in poor soils, making it a great solution for difficult hillsides.

Juniperus conferta

If you need a dense, spreading groundcover, Juniperus conferta is ideal. Its needle-like foliage forms a thick carpet over the ground, helping to suppress weeds and prevent erosion. Juniperus conferta is salt-tolerant and works well in coastal areas, too.

Brunfelsia Scent sational

For those seeking both colour and fragrance, Brunfelsia pauciflora Scent sational (Yesterday Today Tomorrow Plant) offers lovely purple, lavender, and white blooms. It works well on sunny banks, providing interest and stabilising the soil with its strong root system.

Muehlenbeckia axillaris

Native to New Zealand, Muehlenbeckia axillaris (Creeping Wire Vine) is a hard-working groundcover. Its wiry stems and small leaves snake along the soil, anchoring it and reducing erosion, even on steep slopes. It’s also a favourite for creating natural, low-maintenance embankments.

Pimelea mimosa

Another excellent choice for stabilisation and ground coverage is Pimelea mimosa. This low-growing shrub is well-adapted to New Zealand’s conditions, producing clusters of soft pink flowers and a matting habit perfect for steep banks.

Planting Tips for Steep Banks

Establishing plants for steep banks requires careful planning. The best approach is to start with robust groundcovers and low shrubs to anchor the soil, then layer in taller species for structure and visual interest. Mulching between plants can also help retain moisture and suppress weeds. Always consider sun and shade patterns, moisture levels, and drainage before you plant.
