sprouts tiny copies of itself
- Size
- Length: 30–90 cm
- Lifespan
- 20–50 years
- Diet
- Grows in damp, shaded forest understorey, particularly in gullies and along stream banks. Requires consistent moisture, rich organic soil, and protection from direct sunlight. Propagates via bulbils, which are small plantlets that form on the fronds, drop to the ground, and root.
- Habitat
- The hen and chicken fern haunts the damp, shady understorey of lowland forests throughout New Zealand. From Northland to Stewart Island. In the gullies, the stream banks, and the places where the sun is just a rumour. It is not a tree fern. It does not have a trunk. It grows from ground level.
- Range
- Found throughout the North and South Islands, Stewart Island, and the Chatham Islands in lowland and montane forests. Most common in damp, shaded understorey from sea level to 1,000 metres, from Northland to Southland, particularly abundant in wetter western forests.
- Endemism
- Endemic
- Main Threats
- None significant as this species is abundant and secure throughout its range. It is one of New Zealand's most common and widespread ferns, with stable populations in most native forests. Forest clearance has reduced some local populations in recent decades.
- Population
- Abundant and secure. The hen and chicken fern is one of New Zealand's most common and widespread ferns, found from sea level to 1,000 metres in a variety of forest types. It is also widely cultivated as an ornamental plant. No conservation concerns. It is not rare.
- Conservation Status
- Not Threatened
A fern that does not bother with spores. Or rather, it does bother. It produces spores like any respectable fern. But it also has a backup plan. A better plan. This plan involves growing baby ferns directly on its own fronds. It resembles a botanical kangaroo with a pouch full of joeys. The strategy is unconventional. It bypasses the usual risks.
That is the hen and chicken fern. The name tells you everything. The hen is the parent plant. The chickens are the tiny plantlets that sprout from the upper surface of its fronds. They start as small buds. Then they grow roots. Then they grow little fronds of their own. Eventually, they get heavy. The frond bends. The baby ferns drop to the ground. They root themselves. They become new hens. Which make more chickens. Which drop more babies. You see where this is going. The cycle is relentless.
The bulbils make it special. That is the technical term. Bulbils. They are not seeds. They are not spores. They are clones. These are genetically identical copies of the parent plant. They are produced without the need for sex, pollination, or any of that messy business. The hen and chicken fern can produce hundreds of bulbils on a single frond. Each one can become a new plant. It is the botanical equivalent of a photocopier with a jam. The output is consistent. The volume is high.
The fronds themselves are soft, bright green, and finely divided. They look lacy and delicate. They arch up from the base. They reach about a metre in length. The bulbils appear on the upper side of the frond. They are usually near the tip. They look like small green bumps. As they grow, they develop roots and leaves. The frond begins to droop under their weight. The burden is visible.
It reproduces. Relentlessly. The hen and chicken fern is a master of asexual reproduction. It does not need to wait for spores to germinate. It does not need to find a mate. It just grows bulbils. It drops them. It moves on. But it also reproduces by spores. Just in case. The fertile fronds are taller and narrower. They have sporangia on the undersides. The hen and chicken fern covers all its bases. The redundancy is strategic.
It grows in clumps. It forms dense patches on the forest floor. It provides habitat for insects. It offers shelter for small creatures. Its fallen fronds add to the leaf litter. It is not a showstopper. It is not a national symbol. It is just a fern that is very, very good at being a fern. It persists through volume.
In a world where reproduction is risky, where spores might not land in the right place, where seeds might get eaten, the hen and chicken fern has found a better way. It makes babies on its own body. It drops them at its feet. It surrounds itself with its offspring. The proximity ensures survival. The method is efficient.
It is the helicopter parent of the fern world. And it works. No one told it otherwise.
