Renga renga lily Arthropodium cirratum
ABOUT
The plant commonly referred to as the Rengarenga lily or New Zealand Rock Lily is a distinctive perennial that is well-known for its lush, clumping foliage and attractive flower displays. It features long, leathery green leaves that have a glossy appearance and are strap-like in shape. The leaves arch gracefully from the base of the plant, creating a dense and spreading habit that is often described as tufted or clumping. During its blooming period, which generally occurs in late spring to early summer, the Rengarenga lily produces tall flower stalks topped with clusters of star-shaped flowers. These blossoms are typically white, with intricate markings on the petals and a sweet, delicate fragrance. After flowering, small blue-black berries can develop, adding further interest to the plant's appearance. The overall look of the Rengarenga lily is one of elegant simplicity and a soft, textured presence in the garden.

ToxicityTo humans
The rengarenga lily (Arthropodium cirratum) is not generally considered toxic to humans. It does not pose a significant risk if accidentally ingested and is not known for causing poisoning or adverse symptoms in people. However, as with any plant, individual allergies or sensitivities are possible, so it is prudent not to consume this plant unless it is deemed safe by a knowledgeable source.
To pets
The rengarenga lily (Arthropodium cirratum) is also not generally considered toxic to pets such as cats and dogs. It does not typically cause poisoning if pets come into contact with or ingest the plant. That being said, individual animals may have different sensitivities, and eating non-food plants can sometimes result in mild gastrointestinal upset due to the novelty of the material, rather than specific toxicity. Owners should always monitor their pets for any adverse reactions after ingestion of any plant material.

WaterThe Renga Renga Lily should be watered deeply once every week during the growing season; the soil should be allowed to dry out slightly between waterings. Use approximately one gallon of water for each plant to ensure that the water reaches the root zone. In the cooler months, reduce watering to every two weeks, adjusting for rainfall, as the plant's water needs decrease. Always avoid waterlogging as this can lead to root rot, which is detrimental to the Arthropodium cirratum.
LightRenga Renga Lilies thrive in bright, indirect light, but they can also tolerate partial shade. They should be placed where they will receive dappled sunlight for part of the day, ideally receiving morning sun and afternoon shade. Avoid exposing the plant to direct afternoon sun, especially in hotter climates, as this can scorch the leaves and cause stress to the plant.
TemperatureThe ideal temperature range for Renga Renga Lilies is between 50-75 degrees Fahrenheit. They can withstand a minimum temperature of around 30 degrees Fahrenheit but should be protected from frosts. Prolonged exposure to temperatures below this range can damage or kill the plant. Renga Renga Lilies prefer a cooler climate and do not tolerate extreme heat very well.
PruningPruning Renga Renga Lilies is mainly done to remove dead or damaged foliage and to keep the plant looking tidy. The best time to prune is in late winter or early spring before new growth begins. Prune sparingly, as the plant does not require heavy cutting back, and do so annually or as needed to remove spent flowers and leaves.
CleaningAs needed
SoilRenga Renga Lily thrives in well-draining, fertile soil with a slightly acidic to neutral pH of around 6.0 to 7.0. For an optimal soil mix, combine two parts garden soil, one part compost, and one part perlite or pumice to ensure good drainage.
RepottingRenga Renga Lily should be repotted every 2 to 3 years or when it outgrows its current pot. It's best to do this in the spring or early summer during its active growing period.
Humidity & MistingRenga Renga Lily prefers moderate to high humidity levels. Achieve this by placing the plant in a naturally humid environment or by using a humidifier.

Life cycleThe life cycle of the New Zealand Rock Lily (Arthropodium cirratum) begins with seed germination, where the plant emerges from its seed and starts to develop roots and shoots in suitable soil conditions. The seedling then grows into a juvenile plant, developing a rosette of strappy green leaves. As the plant matures, it forms a clump with multiple leaf fans, reaching its reproductive stage where it produces tall flowering stems adorned with clusters of star-shaped flowers, predominantly in spring and early summer. After pollination, typically by insects, the flowers develop into capsule-like fruits that release seeds when mature, completing the life cycle. The New Zealand Rock Lily also has the ability to propagate vegetatively through division of its rhizome, creating clonal offspring that contribute to the expansion of the plant in its ecological niche. Throughout its life, this perennial plant goes through periods of active growth and dormancy, usually in response to seasonal variations in weather and climate.

Spring to Summer
Arthropodium cirratum, commonly known as the rengarenga lily or New Zealand rock lily, is typically propagated by division, which is the most popular method for this species. The best time to undertake division is during the late winter or early spring, just before the plant begins its active growth for the season. To propagate by division, carefully dig up the clump of rengarenga lilies and gently separate it into smaller sections, each with at least one growth point or shoot. These individual sections can then be replanted directly into the garden or into pots using well-draining soil. Water the newly planted divisions adequately to establish them in their new locations. This straightforward method helps to maintain the characteristics of the parent plant and allows gardeners to rapidly increase their stock of rengarenga lilies.
