About this plant
This graceful fern has deep-green, rather erect, evergreen fronds, a brighter green in spring. It is a native plant which may be seen in hedgerows and woodland. It would make a splendid feature in a shaded part of a large rock garden, where it will make a beautiful contrast to the run of rock garden plants. If planted in a niche or crevice a couple of feet above ground level the fronds will be more easily observed.

Spring
Spring-Autumn · Outdoors
Water during drought
In drought conditions where established plants in the ground have had no water for a month, do a deep watering. If drought continues repeat after a fortnight. Plants only need watering during spring to autumn growth. Check plants in pots more often.
Established plants have a good degree of drought tolerance. Water after a prolonged period of drought. Many drought tolerant plants can rapidly revive, even when much of the foliage has died. They will respond with new growth.
Spring - early · Planting
Prune to the ground
Cut foliage to the ground before new growth starts.
Where stems are grown for their ornamental value, old stems should be removed either before new growth starts in spring, or during winter when they begin to look ragged or untidy.
Winter
Winter · Planting
Apply a protective mulch
Protect with a mulch so that the plant does not become too wet in winter.
A mulch is a covering that can: protect the soil surface from rain, heat and cold; deter weeds; provide nutrients. Organic indicates that material has vegetative origin e.g. manure, compost. Synthetics i.e. plastics, or stones are often called mulches.
