Ariane Boston Fern
Nephrolepis exaltata 'Ariane'
The 'Ariane' is a refined cultivar of the traditional Boston Fern, grown for its especially dense and compact growth habit. Its sword-shaped fronds are a deep, bright green and feature a slightly more rigid structure than other cultivars, allowing it to maintain a tidy, rounded shape that is perfect for smaller indoor spaces and decorative containers. Give it bright, indirect light, higher humidity, and steady moisture in a planter with drainage holes.

Care Notes
Light
Position your Ariane Fern in a spot that receives bright, filtered light.
An east-facing window is often ideal. Avoid direct afternoon sun, which will quickly scorch the delicate foliage.
Water
The soil should remain consistently moist but never waterlogged. Water when the very surface of the soil feels barely dry to the touch. If the plant dries out completely, it may begin to drop its leaflets (pinnae) rapidly.
Humidity and Temperature
This plant thrives in high-humidity environments (50% or higher).
If your home is dry, especially in winter, use a humidifier, a pebble tray, or group it with other plants. Avoid placing it near air vents or heaters.
Maintenance
Regularly trim away any brown or yellow fronds at the base using sterilized shears to encourage fresh growth and maintain the plant’s look.
Soil and Planter
Use a well-draining, peat-based potting mix with a slightly acidic to neutral pH. Choose a planter with drainage holes so excess water can escape.
Common Issues
Brown edges often point to dry soil or low humidity. Yellowing can follow waterlogged soil, so check moisture and drainage before watering again.
