Perfectly suited to indoor growing.

It sometimes appears on its own in unexpected places.

• It grows just as well in full shade as it does in part sun.

• It does best in neutral to lightly alkaline soils.

It won’t need much soil, and is a great addition to a flowered stone wall.

Harts tongue fern in a pot

To grow this fern in a pot, indoors, you’ll simply need to make sure it gets enough water.

However, at the same time, the soil must drain extremely well. A great option is to grow it as a hanging fern and to dunk it in water twice a week, then letting it drip dry.

Pruning Hart’s tongue fern

They don’t need any pruning. Eliminate dead leaves after they’ve withered away, once they’re dry.

Removing invasive hart’s tongue fern

Removing a Phyllitis scolopendrium fern that has taken up too much space might be a bit difficult: roots are usually firmly wedged in nooks and crannies on walls and rocky terrain.

Just keep coming back at it for a few more times, removing any growth and coaxing a bit more roots out. Eventually the fern’s root ball will deplete its nutrient reserves and will die off.

This small fern execrates full sun and will always prefer shaded, often more damp areas.

Its growth is relatively slow, and it won’t grow any taller than 20 inches (50 cm). Ideal for an indoor wall garden! As an indoor plant, water it regularly to ensure the soil doesn’t dry off.

The term “hart’s tongue” comes from the appearance of each leaf: like a little tongue of the male deer. The name for a male deer is “hart”.

To reproduce, hart’s tongue produces spores that are lined up on the underside of leaves. These lines look like small millipedes or centipedes: this is where the botanical name “scolopendrium” comes from. Indeed, it’s the old latin word for those two insects!
