Silver Fern Plants

Silver Fern Plant Information

The Silver Fern plant (Cyathea dealbata) is a distinctive tree fern native to New Zealand. It has a tall, slender trunk covered in remnants of old fronds. The fronds are large and feathery, with a bright green upper surface and a striking silvery-white underside.

How Do You Grow A Silver Fern Plant?

Growing a Silver Fern tree, also known as Cyathea dealbata or ponga, requires specific conditions and care for them to thrive:

Choose a good location:

• They prefer filtered sunlight or partial shade. Avoid direct sun exposure, especially harsh afternoon sun if possible as it can scorch the fronds.
• They thrive in moist, well-drained, acidic soil rich in organic matter. You can add compost or similar organic matter to improve the soils fertility and biological activity.
• Silver ferns prefer cool to mild temperatures ideally between 10-21°C (50-70°F). They can tolerate light frost but are not suitable for hot or dry climates.

Planting:

• In colder climates or for when growing them indoors, ensure you plant it in a large pot with good drainage holes. Use a potting mix suitable for ferns.
• When grown outdoors, choose a sheltered location protected from strong winds. Dig a hole slightly larger than the root ball and incorporate organic matter. Gently place the fern in the hole, backfill and firm in gently to remove large air pockets.

Watering:

• Water regularly to keep the soil consistently moist, but avoid overwatering which can lead to root rot. You will need to adjust the watering frequency based on your climate and season.

Fertiliser:

• Apply Native Plant Fertiliser during spring to the soil surface and let the natural rain wash it through the soil.

Additional care:

• Mulching around the base of the fern with organic matter like bark chips helps retain moisture and suppress weeds.
• Remove old or brown fronds as needed to improve aesthetics and encourage new growth.
• Pests and diseases: Silver ferns are generally pest and disease resistant, but keep an eye out for any problems like scale insects or fungal diseases, and address them accordingly.

Remember, patience is key when growing silver ferns, as they are slow-growing plants.

Silver Fern Plant Care

The Silver Fern plant can be challenging to grow outside of its native environment. The best ways to care for your Silver Fern plant is to provide its key requirements.

• Silver Ferns thrive in shady or partially shaded conditions. Avoid direct sunlight, as it can scorch their delicate fronds. Never move a silver fern from a shaded position to full sun without any acclimation as this can causer serious plant injury.
• The soil should be consistently moist but well-drained. Avoid overwatering, as this can lead to root rot.
• High humidity is essential. Regularly misting the fronds can help increase humidity.
• Use a well-draining potting mix rich in organic matter, such as a mix of peat moss, perlite, and compost.
• Silver ferns prefer cool to mild temperatures ideally between 10-21°C (50-70°F). They can tolerate light frost but are not suitable for hot or dry climates.
• Fertilise lightly during spring with native plant fertiliser.
• Watch out for pests like scale insects and mealybugs.
• If you are growing the fern indoors, avoid drafty positions such as beside doors or along thoroughfares.
• Start with a good-sized plant as this will increase your chances of success.

Why Is The Silver Fern Associated With Sports Teams?

The Silver Fern's association with New Zealand sports teams has a rich history and deep meaning, linked to its symbolism as a national emblem:

• Historical Significance: The fern's association with national pride grew further when it was adopted by the New Zealand Army during the Boer War (1898-1902). It later became a symbol of remembrance on the headstones of fallen soldiers in both World Wars, solidifying its link to bravery, sacrifice, and national unity.
• Early Adoption in Sports: As early as 1888, the silver fern was worn by players on the New Zealand Native football team (rugby) during their tour of Britain. This early adoption helped establish the fern as a symbol of national sporting spirit.
• Widespread Use and Nicknames: Today, the silver fern is used by most national sports teams in New Zealand, often incorporated into their jerseys or logos.
• Many women's teams have adopted nicknames incorporating "ferns," such as the Silver Ferns (netball), Black Ferns (rugby union), and Tall Ferns (basketball).

Why Is The Silver Fern NZ’s National Emblem?

The silver fern (Cyathea dealbata) is New Zealand's national emblem due to a few key elements:

• Māori Significance: Māori, the indigenous people of New Zealand, have long revered the silver fern. The silvery-white underside of its fronds would reflect moonlight when they laid fern fronds on the ground to mark trails in the forest, especially when hunting at night. The fern thus symbolized guidance, resilience, and strength.
• European Adoption: Early European settlers were drawn to the fern's unique beauty and its association with New Zealand. It became a common motif in art, design, and literature, further solidifying its place in national iconography.
• Military Symbolism: New Zealand soldiers used the silver fern as an emblem starting in the Boer War (1899-1902), wearing it on their uniforms. It became a source of pride and identity, and later, a symbol for honouring fallen soldiers as it was used on the headstones of those killed in World Wars I and II.
• Sporting Symbol: The silver fern's adoption by the 1888-89 New Zealand Native football team (rugby) solidified its connection with sporting achievement and national pride. Most of New Zealand's national sports teams now proudly wear it, including the world-famous All Blacks.
• Symbol of Unity: The silver fern represents the coming together of Māori and European settlers, embodying a shared sense of belonging and national identity for all New Zealanders.
