Plant Description
Identification and Physical Characteristics
Clianthus maximus , commonly known as Kākābeak or Giant Parrot's Beak (kōwhai ngutu-kākā in Māori), is a woody legume shrub native to New Zealand's North Island Discover more about native shrubs. It is a broadleaf evergreen perennial with glossy dark green, fern-like leaves, typically 15-25 cm long, with 15-30 pairs of leaflets. This striking plant is renowned for its large, dark scarlet flowers, about 80 mm long, which appear in clusters of 15-30 blooms between August and December. These flowers resemble a parrot's beak or lobster claws and are a significant source of nectar for native birds. It can grow as a sprawling shrub between 1.5 to 6 meters tall, with arching branches. The species is critically endangered in the wild, with only a small number of specimens remaining.

Plant Habitat
Natural Occurrence and Ecology
Clianthus maximus, commonly known as Kākābeak, is a woody legume shrub native to the North Island of New Zealand. It is primarily found in scattered populations along the East Coast, from Te Araroa south to northern Hawke's Bay, and in Te Urewera in the west. Its natural habitat includes early to mid-successional shrubland, often dominated by flax (Phormium cookianum and P. tenax) and tutu (Coriaria arborea). This species commonly grows on unstable cliff faces, rock falls, bluffs, coastal cliffs, riverbanks, lake margins, and rocky outcrops. It prefers open, sunny, and steep sites.Clianthus maximusthrives in warm, sheltered microclimates with well-drained, sandy soils that are neutral to slightly acidic and rich in organic matter. It is adapted to grow in infertile sites due to its nitrogen-fixing ability, and its seeds can germinate in response to light gaps created by disturbances like tree-falls or slips. Historically, some inland populations may have been influenced by Māori cultivation.

How to Grow Clianthus Maximus
Cultivating Clianthus maximus(Clianthus maximus) is a rewarding endeavor for any gardener interested in New Zealand's unique flora. This species can be propagated through several methods, each requiring specific conditions to ensure healthy growth and establishment. Successful propagation depends on mimicking the plant's natural environment and providing consistent care during the early stages of development.
From Seed
Propagation from seed is often the most effective way to produce a large number of Clianthus Maximus plants. Seeds should be collected when they are fully mature. Freshly collected seeds generally have higher germination rates than those that have been stored for long periods.
Sow fresh seeds in a seed-raising mix.
- Collect seeds
- Sow in trays
Keep moist until germination.
From Cuttings
For those wishing to replicate specific characteristics of a parent plant, vegetative propagation via cuttings is the preferred method. This technique ensures that the new plants are genetically identical to the source. Semi-hardwood cuttings taken during the appropriate season usually yield the best results for this species.
Take semi-hardwood cuttings in late summer.
- Take cuttings
- Use rooting hormone
Additional Methods
Depending on the growth habit of Clianthus maximus, other methods such as division or layering might also be viable options. Division is particularly suitable for plants that form dense clumps or have spreading root systems, while layering can be used for species with trailing or flexible stems.
Division can be done in early spring.
- Divide clumps
- Replant immediately
Pests & Diseases
Generally resistant to major pests.
While generally resilient, maintaining optimal growing conditions is the best defense against pests and diseases. Regular monitoring allows for early detection of any issues, which can often be managed through cultural practices or organic interventions. Ensuring good air circulation and appropriate watering will significantly reduce the plant's susceptibility to common environmental stresses and pathogens.
Cultural Significance
Kākābeak, or kōwhai ngutu-kākā, holds deep cultural significance for Māori. Its name, meaning "kākā parrot's beak," reflects its striking flower shape. Traditionally, the plant was admired for its beauty and was sometimes used in traditional medicine (rongoā) for its medicinal properties. Its rarity and unique appearance also make it a symbol of New Zealand's unique botanical heritage and the importance of conservation efforts.
- Traditional medicine
- Crafts
Bonus Tip
Excellent for low-maintenance gardens.
For an extra boost, consider applying a thin layer of high-quality organic mulch around the base of the plant. This helps retain soil moisture, suppresses weeds, and gradually improves soil structure as it breaks down. This simple step can make a significant difference in the plant's overall vigor and resilience, especially during periods of extreme weather.

Plant Conservation
Conservation Status
Clianthus maximus, also known as kaka beak or kōwhai ngutu-kākā, is classified as "Nationally Critical" in New Zealand. This conservation status has been in place since 2009.There are only 153 confirmed trees ofClianthus maximusremaining in the wild, a significant decrease from over 1000 in 1996. These wild populations are found in the East Coast and northern Hawke's Bay regions of New Zealand's North Island.The species faces numerous threats, including browsing animals (such as deer, goats, pigs, hares, stock, and introduced garden snails), disease, fire, erosion, habitat modification and loss, natural succession to forest, catastrophic events like floods and landslides, and competition from exotic weeds. Despite its critical status in the wild,Clianthus maximusis widely available in cultivation in New Zealand.
