Dwarf tree fern, Blechnum gibbum, is a tender, evergreen fern which eventually forms a trunk, like a tree fern. Slow-growing, its shuttlecock-like fronds form a crown, giving the fern an exotic look. It’s ideal for growing in a container in a partially shaded conservatory or greenhouse.
Grow Blechnum gibbum in moist, acidic soil or ericaceous compost, in a sheltered spot away from draughts. To increase humidity levels place the container on a tray of pebbles half-filled with water. For best results keep the compost moist but not wet.
