European Polypody | Polypodium Vulgare ‘Cornubiense’

This Fern is indigenous to Europe, Asia as far afield as Japan, Southern Africa and even central regions of North America: in damp areas -like the South West of Britain – it is often found growing on tree trunks, but mostly it clothes steep and shady banks. The European Polypody will tolerate dryish soil as well as damp conditions: for optimum growth, provide some protection from any drying winds in Spring. The European Polypody makes a good patio Fern for those regions of the country where soils and water supplies are very alkaline, and makes an effective ground-cover plant under shrubs. In a large pot, it makes a striking display throughout the Summer, but perhaps is at its best in a woodland setting. Numerous mutants have arisen, and P. v. ‘Cornubiense’ comes originally from Cornwall; the fronds are divided into small segments to give the characteristic lacy effect.

Grow the frost-tolerant European Polypody where it will be protected from any searing winds in late Spring when the new fronds are just emerging. The fronds last until late Winter when they should be removed: in extremely cold regions, fold the fronds over to protect the crown of the plant.

Place this Fern where it will receive light or half shade: as it is at its best from mid Summer to late Winter, position container-grown plants out of sight for the early Spring, or grow it among early Spring bulbs for a year-round effect.

Polypodium vulgare ‘Cornubiense’ is tolerant of both dry and damp growing conditions. Pot-grown plants are best kept just moist: water thoroughly, then wait until the surface of the compost dries before the next watering.

If grown out of direct sunlight, this Fern is remarkably tolerant of low levels of humidity.

Soil-grown plants will require no additional feed: container-grown Ferns should be fed every 2-3 weeks with a liquid plant food from late Spring to Autumn.

Repot and divide Polypodium vulgare ‘Cornubiense’ only when the Fern ceases to show any visible growth; use a loam-based compost and repot the plant in late Spring.

If this mutant produces any fronds which are not divided and lacy, it indicates that the plant is ‘reverting’ to the parent species: any reverting fronds must be removed at once.

Pests & diseases: This tough fern is rarely effected by any pests or diseases and is very tolerant of most cultural growing conditions.
