Cyathea australis, Alsophila australis, Rough Tree Fern

Cyathea australis, Alsophila australis

Rough Tree Fern
Family: Cyatheaceae
Origin: Australia
Small tree 10-20 ftFull sunSemi-shadeKeep soil moistRegular waterOrnamental foliageSeaside, salt tolerant plant

C. australis is commonly known as the Rough Tree Fern due to the presence of adventitious roots, tubercles (knobbly bits) and masses of hair-like scales on its 'trunk'. The 'trunk' like structure on a tree-fern is actually a greatly enlarged rhizome! The horticultural appeal of C. australis is not only due to its beautiful looks but also because it is an extremely hardy species, even capable of tolerating direct sun when the roots are wet. It is also a robust tub plant and is unusual in that it is tolerant of salty winds. C. australis is thus a popular, cold-hardy tree-fern, adaptable to a variety of climates and soils.

Tree-ferns grow best in high humidity and high soil moisture conditions. It is therefore important to use good-quality mulches and to top them up regularly as this will not only keep the soil moist but also provide nutrients to the shallow root system. Tree-ferns usually respond well to organic fertilizers and well-rotted animal manures.

C. australis has a crown of similar size to C. cooperi

but the frond bases are covered in narrow dark brown scales and are quite prickly to the touch.

Cyathea cooperi, Sphaeropteris cooperi, Australian Tree fern, Hapuu Fern

Cyathea cooperi, Sphaeropteris cooperi

Australian Tree fern, Hapuu Fern
Family: Cyatheaceae
Origin: Australia
Small tree 10-20 ftFull sunShadeSemi-shadeKeep soil moistOrnamental foliageSubtropical, cold hardy at least to 30s F for a short time

Cyathea cooperi has a slender trunk usually about 3 - 6" thick, sometimes growing to 30' high, and puts on growth very quickly. The fronds typically will reach about 8' long on a mature specimen, but, as with most tree ferns, they will be significantly stunted if kept in a pot. It will grow well in dappled (but not deep) shade, but also does well in some sun, even in hot climates, as long as the moisture supply is adequate. It also does relatively well in exposed, windy situations. Propagation: Wind-dispersed spores.

Cyathea cooperi - Australian tree fern

Australian Tree fern - one of the most tropical looking plants. Adds "Hawaii" spirit to your garden. It puts on growth very quickly. The fronds typically will reach about 8' long on a mature specimen, but, as with most tree ferns, they will be significantly stunted if kept in a pot. It will grow well in dappled (but not deep) shade, but also does well in some sun, even in hot climates, as long as the moisture supply is adequate. It also does relatively well in exposed, windy situations.

Cyathea medullaris, Mamaku, Black Tree Fern

Cyathea medullaris

Mamaku, Black Tree Fern
Family: Cyatheaceae
Origin: New Zealand, Fiji, Polynesia
Small tree 10-20 ftFull sunSemi-shadeKeep soil moistRegular waterOrnamental foliageSubtropical, cold hardy at least to 30s F for a short time

In New Zealand it is possibly the most common tree fern, and it is found growing in a large range of microclimates and situations throughout the island. It is a rapid grower and makes a very imposing specimen even in less than perfect conditions. Unlike C. dealbata and C. smithii, it generally found growing in open places with full exposure to wind and sun. Its large size and black shiny leaf bases make it a most spectacular plant in cultivation. The ideal situation for it is where its fronds get full sun, but the trunk can remain moist.

Cyathea smithii, Soft Tree Fern, Golden Tree Fern, Katote

Cyathea smithii

Soft Tree Fern, Golden Tree Fern, Katote
Family: Cyatheaceae
Origin: New Zealand
Small tree 10-20 ftFull sunShadeSemi-shadeRegular waterOrnamental foliage

Cyathea Smithii needs total shelter from wind, sun and frost and can be prone to drying out.
It produces masses of very soft and delicate looking fronds which spread horizontally from the crown and reach 2 - 2.5m in length. The trunk is covered in chestnut colored scales, and while it can reach up to 8m in height is fairly slow growing. The old fronds hang down to form a skirt around the trunk, which helps protect it from pests and maintain some humidity.
