Blunt-lobed cliff fern is a North American native. They tolerate temperatures as low as –35°C. Identification: Leaf stalks are scaly, with hairs. Fronds are lacy, 24" (60 cm) × 3" (8 cm), bipinnate. The sterile fronds are evergreen, while the fertile fronds are not. Fronds are light green to gray-green. Sori, the structures that contain the fern's spores, are located on leaf undersides. They form a regular array of dots that are circular or kidney-shaped. Online References:
