Deceptive ferns

Maidenhair and asparagus ferns may be of similar appearance and the names may suggest a close affinity to each other. But in reality they are members of two very different families. Maidenhair is a true fern of

American origin, whereas asparagus fern belongs to the lily family, and hails from South Africa. What they have in common is an aversion to dryness, and a liking for moisture, some humidity, and diffused light. Under conditions which suit them they will thrive, bush out, and have a light fresh green colour all over.

When they do not get the treatment they require, which is far too often, they look a sorry sight indeed, dried out, limp, and almost colourless, unrecognisable and for what they could be — a truly delightful picture.

Adiantum cuneatum, known as maidenhair fern, has attractive, feathery foliage, but is one of the most difficult ferns to maintain in the house. The secrets of success are not complicated: provide a good potting mixture containing plenty of well rotted leaf mould or finely shredded moist peat; keep away from polluted atmos-

pheres, such as smoke; do not place near heating units or in full sun; and avoid dry atmospheres. The bathroom is an ideal place for it, and the addition of rain water or, belter still, placing it out in the rain occasionally will do it good. Although this plant enjoys moisture it does not revel in soggy conditions for too long. Asparagus plumosus (asparagus fern) has a number of forms, mostly differing in the tone of green and width of frond. It is more of a rigid, climbing plant, with feathery foliage, and will pro-

duce bright red berries after it has become well established. The cut stems are used for floral arrangements. A. sprengeri is called Emerald Feather possibly because of its more drooping, reed-like stems, which make it an ideal plant for a hanging basket. Small, white, fragrant flowers, followed by red berries, are an additional feature. Cultural conditions similar to those for maidenhair fern are required, although the asparagus ferns are generally a little more tolerant and do not need humidity.
