Originating from South America, the delta maidenhair fern is a pretty delicate plant in its own right, but can be used to complement and soften other arrangements. The dark green triangular fronds are semierect at first, drooping gracefully with age and can be up to 8 in. (20 cm) long x 6 in. (15 cm) wide. To grow well, il needs moist air, warmth, and shade, preferring a conservatory or bathroom to a living room or hallway.
Size: Height 18 in. (45 cm), spread to 2 ft. (60 cm).
Light: Bright, but indirect.
Temperature: 60—70°F (15—21°C).
Moisture: Keep moist, but do not allow to become waterlogged.
Feeding: Benefits from monthly feeding throughout the growing season.
Propagation: Divide in spring, or break off new clumps from the rhizome with one or two fronds attached.
Special needs: Ferns cannot thrive if they are neglected. They need both moist air and soil; dry air, gas fumes, and cold drafts will harm them, as will allowing the soil to dry out and then soaking it. Remove older fronds as their appearance deteriorates, a few at a time, from right at their base in spring each year to allow space for new shoots to develop.
