About Heart Fern
Heart Fern (Hemionitis arifolia) is a diminutive tropical fern from Southeast Asia, prized for its heart-shaped glossy fronds on slender black stems and compact size under 12 inches. In NE Florida zone 9b it must be grown indoors, in a terrarium, or on a heated, protected lanai — it cannot tolerate temperatures below 60°F and is not outdoor-hardy in this zone. Starting at $14.95.

Care essentials
Heart Fern requires bright indirect light or filtered shade — never direct sun, which scorches the delicate glossy fronds. A north- or east-facing windowsill, terrarium, or shaded lanai is ideal.
Keep soil consistently moist but never waterlogged; root rot is the primary killer. Water little and often, ensuring excellent drainage. High humidity (60%+) is essential — use a pebble tray with water or grow in a terrarium.
Plant in a chunky, airy mix of orchid bark, peat, and perlite. Fertilize at one-quarter strength with a balanced liquid fertilizer every 4–6 weeks during the warm growing season only. In NE Florida zone 9b, grow as an indoor or terrarium plant — it is cold-hardy only to zones 10–11.
