Plant Description

Identification and Physical Characteristics

Bush Lawyer ( Rubus cissoides ), also known as tātarāmoa, is a species of flowering plant in the Rosaceae family, native to New Zealand Discover more aboutNew Zealand. It is a perennial scrambling or climbing vine that can reach lengths of up to 10 meters or more, sometimes climbing over 15 meters high in forests. Young stems are covered in hooked, reddish prickles, especially on the underside, while mature stems are typically unarmed and hairless. The main stems can be stout and reach up to 150 mm in diameter. The leaves are compound, either palmately or ternately, and are smooth and hairless. They have 3-5 leaflets, which can vary in size and shape depending on the plant's age and geographical location. Leaflets are generally lanceolate or oblong, 6-15 cm long and up to 6 cm wide, with sharply toothed edges and pointed tips. Petioles and petiolules also have hooked prickles. The plant produces white (rarely cream) flowers in much-branched panicles, which can be up to 800 mm long. Flowering occurs from September to November. Rubus cissoides is dioecious, meaning individual plants have either male or female flowers. From December to April, it bears orange-red to red berries, which are drupelets up to 12 mm in diameter.

How to Grow Rubus Cissoides

Cultivating Rubus cissoides(Rubus cissoides) 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 Rubus Cissoides 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.

  1. Collect seeds
  2. 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.

  1. Take cuttings
  2. Use rooting hormone

Additional Methods

Depending on the growth habit of Rubus cissoides, 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.

  1. Divide clumps
  2. 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

Rubus cissoides, commonly known as Bush Lawyer or tātarāmoa in Te Reo Māori, holds significant cultural importance, particularly for the Māori people of New Zealand. Its cultural significance stems from a variety of traditional uses. Māori historically usedRubus cissoidesfor a wide range of medicinal applications. Infusions and decoctions made from its bark and leaves were used to treat abdominal pains, diarrhea, stomach aches, sore throats, chest congestion, and colds. It was also valued for its affinity with the female hormonal system, used to address painful menstruation, induce menses, and assist in expelling the placenta after childbirth, sometimes involving vapor baths. Modern applications in traditional Māori medicine (rongoā Māori) include calming an agitated nervous system, promoting sleep, and soothing teething babies. The plant's edible red berries were a food source for Māori and were also used by early European settlers to make jams and stews. The vines can also yield a juice-like beverage. The strong, flexible stems ofRubus cissoideswere traditionally utilized by Māori for binding and construction. Its branches could also be fashioned into traps. The crushed berries of the plant can produce a blue or purple dye. Beyond human uses,Rubus cissoidesis vital to forest ecology, offering food and shelter for native birds. The plant's distinctive thorny nature, which causes it to cling tenaciously, is believed to be the origin of its English name, "Bush Lawyer." In Māori poetry and proverbs, tātarāmoa can also symbolize formidable obstacles.

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

Bush lawyer (Rubus cissoides) is common from lowland to montane forest margins and is assessed asNot Threatened. As a vigorous native bramble it typically benefits from light and disturbance, and conservation concern is low. Nevertheless, retaining native shrub and forest edges, limiting stock access, and controlling invasive vines preserves the mixed tangles where bush lawyer naturally forms. Its flowers and fruit support native invertebrates and birds, so maintaining continuous habitat promotes healthy, self‑sustaining populations.
