How to read these values
These care values are quick reference points for indoor growing. Use them as a guide, then adjust for pot size, substrate, temperature and how quickly the substrate dries.
For more detail, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” shows how far the substrate should dry before watering again.
- Substrate: structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks the cold-stress threshold.
- Humidity: target range; steady conditions usually matter more than exact numbers.
- Growth habit: how the plant grows, such as upright, climbing, trailing, clumping or rosette-forming.
- Support: whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: expected pace under suitable indoor conditions; use as a guide, not a promise.
- Max size indoors: realistic long-term indoor size under good conditions.
- Toxicity & safety: irritation, toxicity or physical hazards such as spines or bristles.
- Origin & habitat: native range, hybrid background or typical habitat where relevant.
- Outdoor growing: when a potted indoor plant can be placed outside and what outdoor protection it needs.
Asplenium antiquum 'Osaka'
Asplenium antiquum 'Osaka' grows as an upright bird’s nest fern with narrow, glossy fronds and strongly rippled edges. The bright green fronds give the rosette a ruffled edge.
Fresh fronds rise from the middle, then lengthen into firmer blades. The ruffled margins become clearer as each frond matures.
What stands out
- Ruffled bird’s nest fern with an upright habit
- Narrow glossy fronds with rippled margins
- Visible central growing point
- Fresh green colour with a clear midrib
- Best with filtered light and steady substrate moisture
Background and naming
Asplenium antiquum comes from East Asia. The 'Osaka' form is grown for narrower fronds and wavy margins, which give the rosette its ruffled edge.
Growing Asplenium 'Osaka'
- Light: Bright indirect or medium filtered light keeps growth steady.
- Watering: Keep the mix evenly moist and let excess water drain fully.
- Substrate: Use a loose fern mix with bark, coco fibre or coir, and perlite or pumice.
- Humidity: Moderate humidity helps the ruffled edges open cleanly.
- Temperature: Keep it in stable warmth, around 16–25 °C.
- Feeding: Use a weak fertiliser during active growth.
- Repotting: Repot when the mix is tired or roots need more space. Keep the centre above the mix.
- Propagation: Spores are slow, and plants grown from spores may not keep the same ruffled form.
Common trouble signs
- Brown edges: Dry air, irregular watering or mineral residue can mark the rippled margins.
- Soft centre: Clear out old debris and water the substrate instead of the rosette.
- Flat new fronds: Give brighter filtered light and keep the centre clear.
- Yellowing fronds: One older outer frond is normal ageing; several at once can point to poor drainage.
Pot growth
Give the rosette room so new fronds can open without rubbing against older growth. Young plants stay compact, while older rosettes can widen when the roots have enough room.
Safety and name note
This fern is generally treated as non-toxic. Place it where curious pets or small children cannot pull at the fronds. The genus name Asplenium comes from the old spleenwort name, and antiquum means old or ancient.
