Tree ferns are perfect for what may be your more difficult garden areas because they prefer shady, sheltered and moist locations.
Tree ferns do like neutral to acidic humus-rich soil, so our alkaline rocky gardens might need supplementing, preferably with compost. To encourage root growth, avoid fertilizing your fern during its first year.
Fairchild Tropical Botanic Garden has many on display, including the Australian tree fern ( Cyathea cooperi), Hawaiian tree fern (Cibotium glaucom), Mexican tree fern (C. schiedei), Caribbean tree fern (Cyathea arborea) and the rare native Florida tree fern (Ctenitis sloanei).
Australian tree ferns can grow to about 20 to 30 feet tall and 10 to15 feet wide. Trunks can grow to about one foot in diameter. They are usually inexpensive, so if you have the proper space, try growing one of these lacy, languid plants
In general, any fern that grows with a trunk elevating the fronds (leaves) above ground level can be called a tree fern. However, the plants formally known as tree ferns comprise a group of large ferns belonging to the families Dicksoniaceae and Cyatheaceae in the order Cyatheales.
Tree ferns are found growing in tropical and subtropical areas, as well as temperate rainforests in South Africa, Australia, New Zealand, and other island groups nearby; a few genera extend further, such as Culcita in southern Europe. Like all ferns, tree ferns reproduce by means of spores developed in sporangia on the undersides of the fronds.
The number of tree fern species is likely to be around a thousand. Although new species are discovered in New Guinea with each botanical survey, many species throughout its range have become extinct in the last century as forest habitats have come under pressure from human activity.
Ferns - Medicinal uses in New Guinea
Fevers, headaches, colds, etc.: Blackwood (1935) mentions that in Bougainville, Selaginella flabellata is used to control feverish headaches and menstruation. The leaves are applied externally and the roots taken internally. In the Mt Hagen area the petiole sap of the common bracken Pteridium aquilinum is used to treat toothache and mouth infections (Powell 1976b). For colds Cyclosorus leaves are used in the Northern Province and for nasal infections the smoke of a species of Polypodium (=?) is inhaled in Mt Hagen (Powell 1976b).
Boils, ulcers, wounds: In east New Britain, Futscher (1959) reports Gleichenia linearis (=Dicranopteris linearis) being bound externally onto wounds. On Bougainville, Blackwood (1935) reports the leaves of Pteris ensiformis and Aspidium latifolium (=Pronephrium menisciicarpon, but possibly a species of Tectaria) and the leaves and roots of Dryopteris milneana being applied to boils, ulcers and arrow wounds. The last two species are probably misidentified. Holdsworth (1980) gives a review of Blackwood's medicinal plant results. In the Northern Province a species of Athyrium is used to treat sores and in New Britain a poultice of boiled fronds of a species of Cyclosorus is used for the same purpose (Powell 1976b). Hot fronds of a species of Polystichum are applied to groin swellings in the Mt Hagen area (Powell 1976b). In Morobe Province, a poultice is prepared from Pityrogramma calomelanos for an unspecified purpose
Stomach pains: Holdsworth & Giheno (1975) record that a species of Lycopodium is chewed in the central highlands to induce vomiting after food poisoning or acute stomach pain. For stomach ache and diarrhoea, in the eastern highlands they report the chewing of fresh fronds of Lygodium longifolium with ash salt ( from Asplenium acrobryum or from the grass Coix gigantea).
Menstruation, childbirth, contraception: Pteris tripartita is used in childbirth in Bougainville, the fronds being taken internally. Pteris ensiformis is used to control menstruation, as is Selaginella flabellata. Lygodium dichotomum is used as a contraceptive, the root and stem being taken internally; it is also used to treat children's illnesses (Blackwood 1935). Peekel (1910) records a species of Dryopteris (most likely to be a species of Thelypteridaceae) being used in New Ireland as an abortifacient (Holdsworth, Hurley & Rayner 1979), however he does not mention the species in his illustrated flora of the island (Peekel in press, ms. completed c. 1947). In the Koiari area of the central province of Papua New Guinea Holdsworth et al. (1980b) note that total sterility in women can be achieved by eating the new leaves of Blechnum orientale each day for three successive days, waiting a fortnight and then repeating the treatment.
Diseases: Holdsworth (1974) reports that on Dobu Island in the D'Entrecasteaux Archipelago, a sorcerer claims to cure leprosy with a draught prepared by shaking the crushed leaf of a species of Lygodium in water.
Native uses: According to Gunther: Rhizome is roasted by the Makah, peeled, chewed and the juice swallowed for coughs; Cowlitz crush the rhizome, mix it with young fir needles, boil it, and drink the infusion for measles; the Quinault either bake the root on coals or use it raw as a cough medicine. Chewed for flavour and used as medicine for colds and sore throats; also used with bitter medicine as a sweetener (Pojar). Method: Strong Decoction from rhizomes, 2-4 ozs, up to 3x daily (Moore); make Licorice
syrup by adding honey to the decoction (Tierra).
Cherokee used Maidenhair for rheumatism (the effect on contracted muscles likened to the uncurling fiddleheads)- the compound decoction or decoction of root applied with warm hands as external rub, or infusion internally. Infusion or decoction of whole plant was used as an emetic for fever and ague (fever with chills).
Powdered leaves are smoked for heart trouble and snuffed or smoked for asthma. They used it for paralytic attacks, as from pneumonia in children. Sacred preparation of whole plant was used specifically for women’s irregular heartbeat.
Cherokee considered Maidenshair a powerful medicine for the heart, and as such it is associated with the direction of East.
Costanoan of California used the decoction to purify the blood and for stomach troubles.
Hesquiat of western Canada mixed the ashes in formula for shortness of breath, and to produce strength and endurance. They likewise used the green fronds.
The northwestern Makah chewed the fronds for weak stomach.
Menomini (Wild Rice People) used a compound decoction of the root for dysentery.
They used the blade, stem, and root in gynecology.
Micmac, Algonquian of eastern Canada, used in decoction for fits.
Potawatomi of the upper Mississippi River used an infusion of the root for caked breasts.
Natives applied poultice of plant to sore back of babies. Wet fronds poulticed for snakebite.
Native American medicinal uses of ferns can be categorized into five major groups: those used
Australian tree fern is a popular ornamental in temperate areas. The pith from the centre of the trunk is rich in starch, and was once used as food by Tasmanian Aborigines. The uncurled leaves (croziers) are also edible, but have a slimy, sometimes bitter taste. The trunks are often used as a medium for growing epiphytes, particularly orchids. Trunks can also be used for fencing, while the central vascular material has been dried and carved to make craft items such as bowls and plant pots.
