Arthropodium cirratum

Rengarenga, Renga Lily, New Zealand Rock Lily


Arthropodium cirratum, commonly known as renga lily or New Zealand rock lily, is a perennial herb native to New Zealand and rarely offered for sale in the UK. It grows as a clump of long, wide green leaves and produces fragrant, star-shaped white flowers on tall, slender stems in late spring to summer.

The plant prefers well-drained soil and full sun to part shade, thriving in coastal and forest environments. Although not reliably hardy, it can take a couple of degrees of frost so could be tried outdoors year-round in the mildest microclimates.

Plant Biography

Arthropodium cirratum, known as renga lily or New Zealand rock lily, is native to New Zealand, where it thrives in coastal and lowland forest habitats. Traditionally, the Māori utilised its rhizomes as a food source.

The plant was first described scientifically in the early 19th century, contributing to botanical studies of the region’s unique flora. Its ornamental value has led to its cultivation in gardens worldwide. Adapted to a range of conditions, it exemplifies the diversity and adaptability of New Zealand’s native plants.

Care & Size Guidance

Care & Size Guidance

To care for Arthropodium cirratum, select a sheltered spot, such as near a south-facing wall, to protect it from cold winds and frost. Ensure the location receives partial to full sun and plant in well-drained soil enriched with organic matter to prevent waterlogging. Water regularly during dry periods, but avoid overwatering, and reduce watering in winter when the plant is dormant. Apply a thick layer of mulch around the base in autumn to insulate the roots against frost. In regions with severe frost, cover the plant with horticultural fleece or a cloche during the coldest months, or consider growing it in a container that can be moved indoors or to a greenhouse during winter.

Feed with a balanced fertiliser in spring to promote growth and flowering. Arthropodium cirratum typically grows to about 50-100cm in height and has a similar spread. Remove old, yellow leaves to keep it looking its best. The plants will form a clump over time and can be easily divided every few years.
