Cut back foliage after flowering to promote a flush of new growth. Propagate through division. Hardy in USDA Zones 8b(15°F) to 11.

Noteworthy Characteristics

Arthropodium cirrhatum, commonly known as renga lily or New Zealand rock lily, is a herbaceous perennial endemic to rocky slopes and woodland margins in the coastal regions of New Zealand. Mature plants can reach 2-3' tall with a similar spread. The glossy, arching, strap-like foliage can reach 1-2' long and 1.5-2.5" wide and emerges from a thickened, fibrous rootstock in tufted clumps. Loose, branched panicles of pendent, white to pink-blushed flowers are held atop 1-2' tall scapes from late spring into summer. The flower stamens are showy, with woolly white and purple filaments adorned with curved, yellow spurs. May be sold under the scientific name A. cirratum.

The genus name Arthropodium means "jointed foot" in reference to the jointed pedicels (individual flower stems).

The specific epithet cirrhatum means "having tendrils or appendages", in reference to the showy stamens of this species.


Snails and slugs can be problematic.
