Hemionitis arifolia
Heart fern
Compact fern with glossy heart-shaped fronds on dark stems — a striking humid-case focal plant.
An epiphytic tropical fern from Southeast Asia with distinctive heart-shaped leaves rather than feathery fronds. It needs high humidity, bright indirect light, and even moisture with an airy mix. Typically 15–25 cm tall in cultivation. Rated intermediate mainly for humidity sensitivity and pest attraction (scale, mealybugs, aphids), not for complex pruning. Quarantine new plants carefully.
Why it works
Unmistakable leaf shape teaches fern care at a beginner-friendly size, and closed cases solve its humidity demand.
Watering notes
Finger-test the surface; water when the top starts to dry but the lower mix is still lightly damp. Soft water preferred where possible. Never leave the crown sitting in standing water.
Care tips
- Use a chunky, well-aerated mix — dense soil invites rot.
- Keep evenly moist; never leave the crown in standing water.
- Aim for high humidity; closed glass is often kinder than open room air in UK heated homes.
- Quarantine new plants — this fern attracts scale, mealybugs, and aphids.
Common problems
- Crispy, curling fronds from low humidity
- Root/crown rot in soggy dense substrate
- Scale / mealybug infestations
