In a 1 litre pot. This unusual and rare house fern looks delicate but it’s as tough as old boots. This one is classed as the most attractive in the genus as it has blue-green leaflets with wavy edges. It has upright leaflets which don’t look familiar fern like as when mature they have only 5 fingers. It requires average warmth above 50F in a location with good indirect light. The compost must be kept moist at all times, but do not overwater as waterlogging will lead to rotting. Mist regularly.
