Waratah flowers: Australia's national flower, they come in red, orange and yellow

Waratah flowers, Australia's national flower, are a stunning Australian native with a beautiful heart shape and a vibrant palette of red, orange, and yellow. The name 'Waratah' comes from the Eora Aboriginal people, the original inhabitants of the Sydney area, and means 'red flowering tree'. The flower is strongly featured in Indigenous Australian legends and was used in a variety of ways, including as a medicinal tonic for children and to infuse water with a sweet floral flavour.

Waratahs are native to the south-eastern parts of Australia, including New South Wales, Victoria, and Tasmania, and are most commonly found in the Sydney area of NSW. They typically grow to around 3 metres in height and thrive in sandy clay areas, where they are mainly pollinated by birds attracted to their nectar and brilliant colour. While the majority of waratahs are red, there is also a commercially available white variety, 'Wirrimbirra White', which has a creamy yellow or greenish hue.

The Waratah has become arguably the most famous and recognisable Australian plant, with its bold and artistic presence in company logos, architectural designs, town names, steamships, and even football teams. New South Wales made the Waratah its state emblem in 1962, and it is now symbolically instated as the floral emblem of the state. The Waratah is also a popular choice for cut flowers, adding a touch of texture and sophistication to vase arrangements and bouquets.

Waratahs are best grown away from plants that require regular feeding, and special care should be taken to avoid fertilisers and composts with high phosphorus or salt content, as these can be harmful to the plant. When planting, ensure that the top of the root ball is level with the top of the garden bed, and gradually reduce watering as the plant becomes established after about two years. Waratahs make a stunning feature plant in the garden and are ideal for low-maintenance gardens and pots, providing lots of spectacular flowers in spring.

Banksia: large flowers loved by insects, butterflies and birds

Banksia is a genus of around 170 species of flowering plants native to Australia, with one species found in northern Australia, New Guinea, and the Aru Islands. They are characterised by their flower spikes, woody fruiting "cones", and large, showy flower heads. Growing as trees or woody shrubs, they can reach heights of up to 30 metres (100 ft) tall.

Banksias are heavy nectar producers, making them a vital food source for insects, butterflies, birds, bats, rats, possums, stingless bees, and various invertebrates. The nectar has been used by the Indigenous people of southwestern Australia, who would suck it directly from the flower spikes or soak them in water to make a sweet drink. The Noongar people of southwestern Western Australia also used infusions of the flower spikes to treat coughs and sore throats.

The flowers are also a source of insect larvae, which are consumed by birds such as cockatoos, who break off the cones to feed on both the larvae and the seeds. Banksia flowers are popular in floristry, often used in large floral installations and bouquets, and are economically important to Australia's nursery and cut flower industries.

The most well-known species of Banksia is the Spinulosa, commonly known as the "hairpin banksia", which can grow up to 30 metres tall. Banksia species are primarily propagated by seed in home gardens, although commercial nurseries often utilise cuttings or grafting methods. Dwarf cultivars and prostrate species are becoming more popular for smaller urban gardens.

Grevilleas are incredibly versatile and can be used as decorative ground cover, shrubs, or trees, making them a perfect addition to any garden or potted plant collection. With their bright and vibrant colours, Grevilleas are a popular choice for those looking to add a bold statement to their garden.

Grevilleas are known for their unique bicoloured flowers, which are produced in abundance all year round. The 'Peaches and Cream' variety, for example, is renowned for its beautiful two-tone blooms. Grevilleas are also loved by native birds and insects due to their nectar-rich flowers. This makes them an excellent choice for those wanting to attract wildlife to their gardens.

The versatility of Grevilleas extends beyond their colour and form. They are well-suited to the Australian climate and can thrive in various soil types. This makes them a low-maintenance option for gardeners, as they can easily establish themselves and are not too demanding in terms of care. Grevilleas are also known for their adaptability, making them suitable for different garden styles and potted combinations.

When choosing Grevilleas for your garden, it is important to consider the specific variety and its characteristics. Some Grevilleas may be better suited to certain climates or soil types than others. Additionally, the size of the plant should be taken into account, as some Grevilleas can grow quite large and may not be suitable for smaller gardens or pots.

Overall, Grevilleas are a popular choice for Australian gardeners due to their vibrant colours, low maintenance, and versatility. With their ability to attract wildlife and add a bold statement to any garden, Grevilleas are a true Aussie icon that can be enjoyed by everyone.

Kangaroo Paw: unique fuzzy foliage in bright pink, red, yellow and green

Kangaroo Paw, also known as sword lily, is a vibrant and unique plant native to Australia. With its tall, fuzzy flowers and long, narrow leaves, it is a striking addition to any garden. The Anigozanthos species, commonly known as Kangaroo Paw, encompasses a wide range of sizes and colours, including bright pink, red, yellow, and green shades.

One of the most popular varieties is the Anigozanthos 'Big Red', which boasts stunning, fuzzy, tubular red flowers that resemble the paws of a kangaroo, hence its name. These vibrant flowers, held on sturdy stalks, can reach up to 5 feet in height. The dark green, iris-like leaves of the 'Big Red' variety are narrow and fold at the midrib, growing up to 3 feet long. This variety is not only visually appealing but also low-maintenance and hardy, making it a perfect choice for gardeners seeking to add a splash of colour to their gardens.

Another variety, the Anigozanthos 'Bush Pearl', showcases pink, fuzzy flowers atop narrow green linear leaves. This variety typically grows to a height of 1-2 feet, making it a charming addition to any garden. For those seeking a bolder statement, the Anigozanthos 'Bush Ranger' is an evergreen perennial with vibrant red flowers on red stems, reaching a height of 2-3 feet.

The Kangaroo Paw plant generally thrives in warm temperatures and prefers full sun, requiring at least six hours of direct sunlight daily. While it can tolerate partial sunlight, full sun exposure will encourage more abundant blooms. Moist, well-drained soil is essential for the plant's health, as soggy soil can lead to root rot. Additionally, the plant benefits from good air circulation, which helps prevent fungal diseases.

With its unique appearance and relatively low maintenance requirements, the Kangaroo Paw plant is a popular choice for gardeners in Australia and beyond, adding a touch of native Australian beauty to landscapes and gardens.
