About this plant
A beautiful fern that makes a clump of leaves that arch up, outwards and then downwards. The fronds have a frilly appearance that give it something of an insouciant character. The fronds are closely packed with individual leaflets (pinnae) but each retains a separate identity. This was discovered growing in Dahlem Botanic garden in Germany. Note: there are a number of incorrectly named variants on the market.

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.
