As you might be able to guess from its name, the tall kangaroo paw is a plant that is native to Australia. These plants can range in color from yellow, orange, red, pink, or purple. Interestingly, the flowers on the tall kangaroo paw plant vary with the temperature, and are more vibrant in cooler temperatures.
I. Appearance and Characteristics
Anigozanthos flavidus is a species of plant found in Southwest Australia. It is member of the Haemodoraceae family. It is commonly known as the tall, yellow, or evergreen, kangaroo paw. The specific epithet, flavidus, refers to the yellow flowers of this plant.
A member of the genus Anigozanthos (kangaroo- and cats-paws) that has an evergreen clump of strap-like leaves, up to 1 metre long and 0.02 m wide, growing from an underground rhizome around 0.05 m in diameter. The rhizome allows the species to regenerate after drought or fire. Each plant may produce over 350 flowers, on up to 10 long stems, these appear during the summer of the region. Pollen is distributed by birds as they plunge into the flowers to reach the nectaries. Flowers are frequently yellow and green, but may present in shades of red, pink, orange, or brown. It is found along roadsides, along creeks, and in forests and swamps, and other unshaded winterwet habitat.
The species occurs in a range from Two Peoples Bay in the southeast, throughout the Warren and southern Jarrah Forest, to Waroona on the Swan Coastal Plain. It was previously endemic to the region, but is now naturalised in New South Wales. This kangaroo paw is now widely cultivated in the Eastern states of Australia and the United States of America. Anigozanthos flavidus hybridises with other members of the genus, and is used in the development of cultivars. It is a hardy plant, tolerant of a wide range of soil types and condition, that may live for around 30 years in a garden. It is propagated from seed or sections of the rhizome.
The first description of the species was by Augustin Pyramus de Candolle in 1807. This was published in Redouté’s Les Liliacees with an illustration by that artist.
II. How to Grow and Care
Sunlight
Tall kangaroo paw thrives in conditions offering full sun exposure, which bolsters its growth and augments its flowering potential. Though a tall kangaroo paw tolerates partial sun, any substantial reduction in light could diminish both vibrancy and the abundance of blossoms. In outdoor settings, tall kangaroo paw prefers a position that bathes in sunlight for most of the day, ensuring its distinctive flowers and foliage develop optimally.
When placed indoors, a location that simulates such luminosity, like a south-facing window, is most beneficial. Adaptive traits, such as leaf orientation, may manifest to maximize light absorption in suboptimal conditions.
Temperature
As a native to Australia, tall kangaroo paw is highly drought-tolerant and can be expected to continue flourishing even if summer temperatures are very high. If your local climate experiences frost at any time of the year, it is best to grow your tall kangaroo paw in a container under the eaves of a building or under the canopy of a tree. The optimum growing temperature for the plant is between 15 to 35 ℃. Several of the more commercial varieties are highly tolerant of saline maritime conditions.
Watering
Tall kangaroo paw thrives in well-drained soils, typical of its origins in the arid regions of Australia. This species exhibits a high drought tolerance and prefers dry conditions over excessive moisture. Watering should be sparse, aligning with its adaptation to infrequent rainfall, translating to once every two weeks. Tall kangaroo paw is predominantly an outdoor plant, flourishing under direct sunlight which intensifies its need for thorough but infrequent watering, ensuring that roots remain healthy without waterlogging – a crucial balance for this sun-loving perennial.
Soil
Tall kangaroo paw thrive in well-aerated soil that ensures proper drainage to prevent water-logging. A suitable soil mix consists of 60% potting mix combined with 40% sand or perlite for enhanced drainage. If sand isn’t available, gravel can be a substitute. Incorporate a slow-release fertilizer at the start of the growing season. Monitor watering to maintain soil moisture without oversaturation. This blend promotes healthy root development and optimal growth.
Fertilizing
For optimal growth, tall kangaroo paw benefits from regular fertilization with high-nitrogen formulas, particularly during its active growth in spring and summer. Monthly applications of diluted, balanced fertilizer support lush foliage and vibrant blooms, enhancing plant vigor. Use quarter-strength recommendations to prevent root burn. Seasonal adjustments are critical, with reduced feeding in autumn and a rest period in winter. Always water tall kangaroo paw before applying fertilizer to safeguard the roots. Following these guidelines ensures a robust tall kangaroo paw with prolific flowering.
Pruning
Tall kangaroo paw responds really well to heavy pruning. After blooms have faded, all plant parts should be cut back to 15 cm above the ground. This will not only help the plant to overwinter, but may even enable a second, smaller bloom before the end of the current growing season. Plants can also be divided in the spring to ensure that there are new plants available for the following growing season.
Propagation
Tall kangaroo paw propagates best through division in Spring or Autumn. Propagation is moderately easy; success is indicated by new shoots and root growth. Ensure adequate moisture to encourage healthy plant development.
Transplanting
The perfect time for transplanting tall kangaroo paw is between mid-spring and early summer, when the weather is warming and plants flourish. Choose a sunny, well-drained location to replicate its native habitat. Carefully transplant your tall kangaroo paw to avoid damaging its long taproot system.
Repotting
Repot tall kangaroo paw in spring, every 2-3 years to accommodate its growth. This tall, bushy perennial thrives in a slightly larger pot to support its long, fibrous roots. After repotting, place it in well-draining soil and offer plenty of sunlight. Water moderately, as tall kangaroo paw is hardy but appreciates consistent moisture post-transplant. A friendly reminder – be gentle, tall kangaroo paw’s roots are delicate!
III. Uses and Benefits
Tall kangaroo paw is a popular perennial prized for its height and uniquely shaped colorful blooms. It is commonly used as an ornamental garden plant and is essential in summer flower gardens. Plant it with wattle and Scaevola for texture and contrasting color.
