Asplenium nidus 'Crispy Wave'

The Japanese selection history of Asplenium nidus ‘Crispy Wave’

Yuki Sugimoto selected Asplenium nidus ‘Crispy Wave’ on Yaku Island in 2000 from an unnamed offspring of ‘Osaka’. The breeding line began with a mutation of ‘Osaka’ selected by Haruo Sugimoto in 1961 and refined through repeated spore propagation and selection.

Wild Asplenium nidus ranges from Malesia to northern and north-eastern Queensland, growing on trunks, branches and rocks in humid forest.

Moisture and airflow for healthy fronds

Light

Stand Asplenium nidus ‘Crispy Wave’ near a bright east or north-east window, with no hot sun on its deeply waved fronds. In deep shade the crown grows slowly and new fronds are narrow; intense rays scorch the raised waves before flatter tissue.

Watering

Maintain steady moisture around Asplenium nidus ‘Crispy Wave’ without leaving it saturated. The fine roots and waved frond edges respond poorly to a hard dry-out. Water around the edge of the root ball when the surface begins to dry, keeping the crown dry and allowing surplus water to drain.

Temperature

Grow Asplenium nidus ‘Crispy Wave’ in stable indoor temperatures and protect it from chilling temperatures. Avoid abrupt changes while the central frond is unfolding, because soft tissue does not recover from a crease or chilled patch.

Humidity and airflow

Moderate to high humidity helps Asplenium nidus ‘Crispy Wave’ maintain clean frond edges, provided air can move around the crown. Ordinary room air may work, although the deep waves become crisp in a direct heater stream.

Fertilising

Use a complete foliage fertiliser for Asplenium nidus ‘Crispy Wave’ at a low dose during active crown growth.

Leaf care

The pronounced waves of Asplenium nidus ‘Crispy Wave’ are part of each frond and should not be flattened. Cut an exhausted outer frond at the base and leave soft central growth untouched.

When Asplenium nidus 'Crispy Wave' needs attention

• Glossy fronds have pleated, crimped edges and curled tips: These stiff, wavy margins are the intended ‘Crispy Wave’ shape. Drought damage is brown and brittle, whereas a healthy cultivar ripple stays green and flexible.
• New fronds flatten or lose much of their ruffle: A change in fresh growth can follow weak light, excessive sun or root stress. Stabilise bright filtered light and moisture, then judge the next few fronds; existing blades cannot be reshaped.
• A central frond blackens before it unfolds: Crown rot is a risk when water collects in the tight nest. Water around the mix instead, remove loose debris and avoid probing a firm living growth point.
• Crimped edges turn brown in fine lines: Root dryness, mineral salts or hot airflow may be reaching the extended margins first. Rehydrate evenly, flush the mix and move the fern away from heating vents; dead edging will not become green again.

Asplenium nidus ‘Crispy Wave’ is non-toxic to cats and dogs

• This plant is non-toxic to cats and dogs.
• Its effects on people are unclear, so keep it away from young children who may chew it.
• Eating a large amount can still cause an upset stomach. Seek medical or veterinary advice if symptoms continue.

About the name Asplenium nidus and the history of ‘Crispy Wave’

Asplenium comes from the old Greek name asplenon, linked with splen, spleen. The Latin epithet nidus means nest and refers to the nest-like rosette formed by the fronds.

Yuki Sugimoto selected ‘Crispy Wave’ in 2000 during a breeding programme on Yaku Island, Japan. It arose among descendants of ‘Osaka’ and received United States plant patent PP20982 in 2010.

Carl Linnaeus established the genus Asplenium in 1753 in Species Plantarum, page 1078.

Carl Linnaeus first described Asplenium nidus in 1753 in Species Plantarum, page 1079.
