Sophora molloyii Dragons Gold is a compact and hardy NZ native evergreen shrub that stands out for its vibrant golden-yellow flowers. This unique variety blooms even earlier than its relatives, gracing gardens with its prolific flowers in winter. The fern-like, bright green foliage complements the radiant colours, making it a visual treat throughout the year. Growing to an approximate height and width of 2 metres, Dragons Gold is versatile and fits perfectly in border plantings and pots, and can even be trimmed into an attractive hedge.
Not just a treat for the eyes, this Kowhai variety is a favourite amongst native birds such as tui and kereru, who are drawn to its nectar-rich flowers. It thrives best in well-drained soil and can tolerate sunny and semi-shaded spots in the garden.
Astelia fragrans is a hardy, evergreen perennial native to New Zealand, featuring arching, sword-shaped leaves in shades of green with a soft silvery underside. In Spring, it produces small, fragrant flowers hidden among the foliage, followed by orange berries on female plants, adding subtle seasonal interest.
Ideal for native gardens, woodland plantings, or shaded borders, this Astelia thrives in part shade with moist, well-drained soil. It tolerates wind and light frost, making it suitable for exposed sites. Space plants approximately 80–100cm apart to allow their natural form to develop.
Matures to around 1m tall and 1.2m wide, creating a soft yet structured presence in the garden.
Phormium cookianum, more commonly known as mountain flax or wharariki, is endemic to New Zealand and is a very useful plant for any native planting project. Despite its common name, it is found throughout New Zealand from coastal slopes to alpine treelines.
Phormium cookianum is smaller than the New Zealand flax Phormium tenax/harakeke, rarely reaching more than 1.6m, and its leaves and seed pods droop and twist more. The flowers are a source of nectar for the native birds, especially tui and bellbird/korimako.
Carex secta, commonly known as Pukio, Makura or swamp sedge, is a robust perennial grass native to New Zealand, renowned for its lush, bright green, strap-like leaves and dense clumping habit. It naturally occurs in wetlands and swampy areas, indicating its preference for moist, boggy conditions.
In the garden, Carex secta is ideal for creating naturalistic plantings, especially in wetland or water garden settings. It can be used for erosion control, along waterways, or in areas where water accumulates, providing both aesthetic appeal and environmental benefits.
Makura prefers full sun to partial shade and thrives in wet, boggy soils, making it a perfect choice for areas that are difficult to plant due to excessive moisture. It can also adapt to drier conditions once established, but it truly excels in environments that mimic its natural wetland habitat. When planting, a spacing of about 50-70cm apart is recommended to allow the plants to spread and form a thick, lush mass.
The mature: Can reach heights of up to 1-2m with a similar spread.
Coprosma Hawera is a fast-growing, low-lying New Zealand native that creates a dense mat of small, narrow olive-green leaves. Its hardy nature allows it to thrive in various conditions, though it has a preference for dry areas. Its cascading growth habit is especially stunning over walls or down banks. When fully grown, Coprosma Hawera typically measures around 50cm in height and can spread up to 1m wide, offering excellent ground cover. A great native for supressing weeds.
Pittosporum Golf Ball is a neat forming, rounded New Zealand shrub. This plant is ideal for adding structure and architectural interest to the planting scheme and also makes a great low hedge. Small purple flowers appear in late spring and early summer with a sweet, honey-like scent. Frost hardy and likes a spot in the full sun and partial shade with a moist, well-drained soil. Grows to a height of 1m but can be trimmed to retain a smaller shape.
