About This Plant

Crispy Wave Fern (Asplenium nidus Crispy Wave) is a Japanese-bred cultivar of the Birds Nest Fern, native to tropical and subtropical Asia, Australia, and East Africa. It grows in bright, deep green and reaches 30 to 60 cm tall and wide indoors.

The ruffled wavy edges make it visually textured. The flat frond of the regular Birds Nest Fern is elegant but simple. The Crispy Wave version adds dramatic crinkled ridges that run from midrib to frond edge, creating a sculptural, almost pleated look.

Safe for cats and dogs. The ASPCA confirms Asplenium nidus is non-toxic to cats and dogs. The Crispy Wave, as a cultivar of Asplenium nidus, carries the same confirmed pet-safe status. The Austral Gem Fern is another confirmed pet-safe Asplenium fern with a very different glossy, deeply divided frond.

It handles average Canadian indoor conditions better than most ferns. Like its parent plant, the Crispy Wave tolerates lower humidity and moderate indirect light better than Boston Ferns, Maidenhair Ferns, or most other fern varieties commonly sold in Canada.

Winter Slowdown

Growth slows from November onward but the Crispy Wave stays green and holds its fronds well through winter. The main challenge is dry air from forced-air heating. Keep the soil consistently moist, keep temperatures above 18 degrees C, and keep it away from heating vents.

Toxicity

Non-toxic to cats and dogs, confirmed by the ASPCA (Asplenium nidus). As a cultivar of Asplenium nidus, the Crispy Wave carries the same confirmed safe status. Safe for homes with pets and small children.

Pests

Scale insects are the most common pest on Asplenium ferns, appearing as small brown bumps on the undersides of fronds or along the central stem. The Crispy Wave is also occasionally affected by mealybugs where the fronds emerge from the central rosette.

Other Plants You Might Like

Not sure this is the right fit? Here are three other plants our Canadian customers love. All ship across Canada and thrive in Canadian homes.

Birds Nest Fern. Same family, smooth fronds.

For the same Asplenium nidus plant with smooth, flat fronds instead of ruffled ones, the Birds Nest Fern has broad, wavy fronds in a classic rosette and the same low-maintenance character and pet-safe status.

Austral Gem Fern. Glossy and tough.

For another pet-safe Asplenium fern that handles dry Canadian indoor air even better, the Austral Gem Fern has thick glossy deeply divided fronds and is one of the most low-maintenance ferns available.

Blue Star Fern. Distinctive blue-green.

For a pet-safe fern with a very different blue-green colour and wide lobed fronds that also handles average indoor humidity well, the Blue Star Fern suits the same lower-light spots in Canadian homes.

Common Questions

How often should I water the Crispy Wave Fern?

Keep the soil consistently moist. Water around the rim of the pot when the top inch feels slightly dry, roughly every five to seven days in spring and summer. In a Canadian winter, every seven to ten days. Never pour water into the central rosette as this causes crown rot. Our indoor plant watering guide shows how to check moisture correctly.

How is it different from a regular Birds Nest Fern?

The Crispy Wave is a cultivar of the same species (Asplenium nidus) but with dramatically ruffled or crinkled frond edges that give it a much more textured, three-dimensional appearance. The care is identical. The main choice between them is visual: flat and elegant versus ruffled and sculptural.

Is the Crispy Wave Fern safe for cats and dogs?

Yes. As a cultivar of Asplenium nidus, which the ASPCA confirms is non-toxic to cats and dogs, the Crispy Wave carries the same confirmed pet-safe status. Safe for homes with pets and small children.

What light does it need in a Canadian home?

Medium to low indirect light works well. A north- or east-facing window is ideal. It handles lower light better than most tropical plants. Direct sun bleaches and scorches the fronds. Read our guide to light requirements for indoor plants to find the right spot.

Will it survive a Canadian winter indoors?

Yes. Keep it above 18 degrees C, away from heating vents, and keep the soil consistently moist. It handles average indoor humidity better than most ferns, making it one of the more practical fern choices for Canadian winters. Read our tips on keeping plants alive in winter for more.

Good to Know

Sun: Indirect

Medium to low indirect light works well. A north- or east-facing window suits it year-round in Canadian homes. The ruffled fronds are more textured than a smooth fern and catch available light from multiple angles. Direct sun scorches the fronds.

Light: Medium to low indirect

A north- or east-facing window is ideal year-round. One of the better ferns for lower-light Canadian conditions. From October to February, keep it in the brightest indirect spot available without exposing it to cold drafts from the glass.

Water: Keep soil consistently moist

Water when the top inch of soil is slightly dry. Keep soil consistently moist but not waterlogged. Water around the pot rim, never into the central rosette. Every five to seven days in spring and summer, every seven to ten days in a Canadian winter.

Humidity: Moderate to high

Handles average indoor humidity better than most ferns. A pebble tray nearby helps during the dry heating season in Ontario and Quebec from November to March. A full humidifier is not required but is beneficial if the room is very dry.

Pet Friendly: Yes

Non-toxic to cats and dogs, confirmed by the ASPCA (Asplenium nidus). As a cultivar of that species, the Crispy Wave is confirmed pet-safe. Safe for homes with pets and small children.

Pro Tip

The fuzzy brown central rosette of the Crispy Wave serves the same function as in the regular Birds Nest Fern: it collects falling debris in the rainforest, not water. Pouring water into it indoors causes crown rot from the inside out. Always direct water onto the soil at the pot rim.
