Lemon Button Fern
Nephrolepis cordifolia 'Duffii'
A compact fern featuring upright to arching fronds adorned with small, rounded, button-like pinnae that emit a subtle citrus scent when brushed.
- Light
- Bright, indirect light for 4 to 6 hours daily; protect from direct hot sun to prevent frond scorch.
- Water
- Water frequently whenever the top surface of the soil begins to feel slightly dry. Never allow the root system to dry out completely, and ensure excess water drains freely.
- Growth
- Perennial herbaceous fern with a compact, clumping growth habit, reaching mature heights and spreads of about 12 inches.
Care instructions
Provide bright, indirect sunlight and keep the soil consistently moist but never waterlogged. Maintain high ambient humidity levels and use a well-draining, organic potting mix. Feed lightly with a balanced liquid fertilizer during the active growing season.
