Asplenium nidus is an epiphytic fern and part of the Aspleniaceae family. Its native range is Malesia to N. & NE. Queensland, it is often called 'Birds nest fern'. It’s lanceolate-shaped fronds are extremely stiff and curvy. ‘Crispy Wave’ is a product of a planned breeding program conducted in Yaku Island, Kagoshima Prefecture, Japan; it is naturally occurring whole plant mutation of the unpatented Asplenium nidus ‘Osaka’ discovered by Haruo Sugimoto, in 1961. However, it wasn’t until after many more years of selection and spore propagation that his grandson, Yuki Sugimoto became the inventor.
The genus name is from the New Latin for ‘spleenworts’ and the specific epithet nidus is from the Latin for nest.
Light: Bright indirect light, meaning the plant sees the sun for 0-4 hours per day - this could be through trees or a translucent curtain, it’s important for the plant to see the sky in order to thrive.
Water: Asplenium nidus prefer their substrate to be consistently moist, allow the top inch of the mix to dry out. Pour water slowly over the top of the substrate and allow the water to pass through the drainage holes; avoid pouring water into the heart of the plant.
Potting mix: A rich well draining mix with amendments of leaf mold, sand and grit. These plants only have shallow root systems so it is important to keep the rhizomes at the substrate surface.
Fertilising: Feed your plant every few waterings during the growing season or when you observe active growth. You can dilute fertiliser to half the recommended amount but never add more.
Temperature: Ideally 18-28°C, no cooler than 15°C.
Humidity: Asplenium would prefer higher humidity. You can increase humidity by placing the plant on a watered pebble tray or using a humidifier.
