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 metrics
These metrics are standardised reference points. We compile them by reviewing and cross-checking multiple botanical and horticultural references, then refining them through real-world growing experience. Source links: Plant Care Resources.
Please use the values as guidance. Conditions vary by home, so the same plant can respond differently. For plant-specific context, read the full product description and browse our Plant Care Guides.
- Light: level + approximate lux at leaf level;
- Watering: “% dry” is the trigger before watering again; lower % stays more evenly moist.
- Potting mix: one-line profile (structure/drainage • moisture buffer • base • particle size).
- Temperature: “Ideal” comfort range; “Avoid below” marks higher stress risk.
- Humidity: target bands (Normal/Moist/Humid); consistency usually matters most.
- Growth habit: growth form (rosette, trailing, climbing) for placement and training.
- Support: needed/optional/none, whether stake, pole, or trellis improves structure and size.
- 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: chemical irritants/toxicity and physical hazards (spines, bristles).
- Origin & habitat: native region + typical biome/habitat as context.
