About Southern Shield Fern
Southern Shield Fern (Thelypteris kunthii) is a Florida native semi-evergreen fern producing tall, light green triangular fronds 3–4 feet tall in shaded to partly shaded gardens. Drought-tolerant once established and deer resistant, it is an excellent low-maintenance groundcover for moist, shaded spots in NE Florida landscapes. Starting at $9.95.

Care essentials
Light
Grows best in part shade to full shade. Protect from hot afternoon sun in NE Florida, which can scorch the fronds. Ideal under tree canopy or on north- or east-facing exposures.
Water
Appreciates consistently moist soil but shows good drought tolerance once established — an important trait for NE Florida sandy soils. Water regularly during dry spells; mulch heavily to retain soil moisture.
Soil & Fertilizer
Tolerant of a wide range of soils including sandy, loam, and clay, provided moisture is adequate. Amend NE Florida sandy soils with compost to improve water retention. Apply a light balanced slow-release fertilizer in spring; this native fern generally needs minimal fertilization.
