Adiantum raddianum 'Fritz-Lüthi' at a glance:
Adiantum raddianum 'Fritz-Lüthi' keeps the airy maidenhair look but packages it in a denser, slightly sturdier form, with larger triangular fronds and firmer black stipes than many standard selections. New growth opens bright green and matures to a softer blue-green tone, which gives the plant more depth than a flat green fern.
It prefers bright indirect light, constant but not stagnant moisture, and humidity around 60–80%, paired with warmth between 18–24 °C. Letting the root ball dry even briefly can set it back quickly. A light organic mix with fine bark or perlite works well, and regular stability matters more than heavy feeding if you want the fronds to stay fine, full, and evenly coloured. Repotting is best done before the roots become dense and felted.

How to read these values
These care values are practical reference points for indoor growing. Use them as a starting point, then adjust for your room, pot size, substrate, temperature and how quickly the plant dries.
For more context, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” is the trigger before watering again; a lower % means the mix stays more evenly moist.
- Potting mix: a quick profile of structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks where stress risk increases.
- Humidity: target bands (Normal/Moist/Humid); consistency usually matters most.
- Growth habit: growth form (rosette, trailing, climbing) for placement and training.
- Support: shows whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: fast/average/slow under decent indoor conditions—expectations, not a promise.
- Max size indoors: realistic long-term potential; format differs for climbers vs. trailers.
- Toxicity & safety: irritating or toxic compounds and physical hazards such as spines or bristles.
- Origin & habitat: native region and typical habitat context.
