Nephrolepis cordifolia (Sword Fern) – An evergreen fern with tufts of erect finely-toothed sword-shaped fronds that rise grow to 2-3 feet tall from short hairy somewhat tuberous rhizome stems that spread out at or just below soil level. The leaves are a deep green with brown spores visible on the underside of the leaf.

Plant in shade or part sun (will take coastal full sun with regular watering) and tolerate drier, poorer soil than most ferns. Hardy to 20°F but rebounds from the ground after a frost so useful in USDA zones 8b-10b. A fern long-cultivated in California that is useful in gardens for its toughness and ability to survive in relatively dry conditions. It is impressive as a tall groundcover for woodland areas and useful as an accent plant or in hanging baskets and containers.

Nephrolepis cordifolia is native to northeastern Australia north into Asia where it is found growing in swamps, low lying wet areas and sometime as an epiphyte, but it is well established throughout the world in the tropics and subtropics. The name for the genus comes from the Greek words 'nephros' meaning "a kidney" and 'lepis' meaning a 'scale' for the shape of the specific epithet means "heart-shaped leaves". It is related and similar looking to the so-called Boston Fern, Nephrolepis exaltata, that is widely used as an indoor plant. We also have grown the dwarf form with light green rounded leaves that is called Nephrolepis cordifolia 'Lemon Buttons'
