The plight of Cordyline australis in the Sudden Decline epidemic drew attention to another widespread threat to the tree in rural areas throughout New Zealand. It is one of the easiest exotic plants to grow. Flowering takes place over a period of four to six weeks, giving maximum exposure to pollinating insects. It is very popular in the Morecambe area … ... cordylines do also produce a spectacular cluster of white flowers (followed by small red or purple berries), during particularly good summers. ID: TA880W (RF) Tricolor Hawaiian Ti Plant, cordyline fruticosa, used for thatching and clothing. These plants have panicles of flowers and berries adding to their garden appeal. Right: Cordyline indivisa Endlicher 1836 (Mountain or Broad-Leaved Cabbage Tree) has much wider glaucous leaves than Cordyline australis. [12] It is more common in Southern England and in Ireland where it is grown all over the island. [78] The seeds of Cordyline australis are high in linoleic acid, one of the essential fatty acids. The leaves were rubbed until soft and applied either directly or as an ointment to cuts, skin cracks and cracked or sore hands. Monday—Friday: 9:00AM–5:00PM Registered Company No.05695741 Online Resource for Backyards & Gardens. [81], In the North Island,[82] Māori cultivated selected forms of C. australis for food. Cordyline Purple Cabbage Palm, From Amazon. Cordyline australis, commonly known as the cabbage tree or cabbage-palm,[3] is a widely branched monocot tree endemic to New Zealand. The foliage turns yellow, and the oldest leaves wither and fall off. 61 Mosley Street, Manchester, Torbay Palm is a popular choice for coastal and urban gardens in the warmer parts of Britain because it gradually sheds the older leaves giving it an exotic palm-like appearance. If you intend on growing cordyline outdoors, the best time to plant this hardy evergreen tropical plant is in the spring, but after the risk of any potential frost has ended. [26] In Taranaki, cabbage trees generally have a compact canopy with broad straight leaves. C. australis ‘Albertii’ has wonderful green cream and white variegations in its leaves. Once established, these tropical plants are relatively easy to care for and do not require a lot of maintenance. Though its flowers generally bloom in the late spring to early summer, if you're planting your cordyline indivisa in a pot or container, these plants will rarely flower. [52] Because it takes about two years for a particular stem to produce an inflorescence, cabbage trees tend to flower heavily in alternative years, with a bumper flowering every three to five years. It can renew its trunk from buds on the protected rhizomes under the ground. In Marlborough's Wairau Valley, cabbage trees tend to retain their old, dead leaves, lending them an untidy appearance. Removing any dead leaves, spent flowers, and damaged stems are really the only things that you will need to attend to. [64], Cases of sick and dying trees of C. australis were first reported in the northern part of the North Island in 1987. The leaves of the small specimen shown here were about 4 inches wide in the middle compared with around 2 inches wide for those of C. australis. AH & AW Reed. As young plants, they look great in pots and beds. Just remove any spent blooms and dead leaves from the plant as you see them. [80] It is easily grown from fresh seed — seedlings often spontaneously appear in gardens from bird-dispersed seed — and can be grown very easily from shoot, stem and even trunk cuttings. [74], The kōata, the growing tip of the plant, was eaten raw as medicine. The single stemmed trees then develop branches and flower even more prolifically. It produces impressive panicles of small, sweetly scented white flowers in late spring to early summer, on mature plants. Press Esc to cancel. Given the fact that they are a tropical plant, they should only be grown outdoors in the warmest climates (in the United States, they’re only hardy outdoors through zone 9); otherwise, they should be grown indoors as houseplants. If you are interested in adding some color to your tropical outdoor garden or you’d like to bring some interest to your indoor garden, you might want to consider cordyline. Showy and vigorous, Cordyline australis 'Red Star' (Cabbage Palm) is a palm-like, sub-tropical tree with arching, sword-like, dark burgundy leaves. [24] When growing in the open, tītī can become massive trees with numerous, long thin branches and relatively short, broad leaves. With its tall, straight trunk and dense, rounded heads, it is a characteristic feature of the New Zealand landscape. Cordyline australis has many ecological associations in its native New Zealand but these plants and animals are usually not found on this continent significantly lowering its ecological impact. The generic Māori language term for plants in the genus Cordyline is tī, and names recorded as specific to C. australis include tī kōuka, tī kāuka, tī rākau, tī awe, tī pua, and tī whanake. [4][14] The leaves grow in crowded clusters at the ends of the branches, and may droop slightly at the tips and bend down from the bases when old. [38] These include what the plant looked like—whether it was a large tree (tī rākau, tī pua), the whiteness of its flowers (tī puatea), whether its leaves were broad (tī wharanui), twisted along the edges (tī tahanui), or spiky (tī tarariki). Cordyline australis ‘Red Star’ is a compact plant, with evergreen long, thin, arching, bronze-red leaves. At the same time, the bark on the trunk becomes loose and detaches easily. Flowering spikes of Cordyline australis in Cornwall, UK.

[56], Animals and birds associated with C. australis include lizards which forage among the flowers, including the gold-striped gecko which is well camouflaged for life among the leaves of the tree. The liquid from boiled shoots was taken for other stomach pains. The stamens are about the same length as the tepals. [40], Cordyline australis occurs from North Cape to the very south of the South Island, where it becomes less and less common,[41] until it reaches its southernmost natural limits at Sandy Point (46° 30' S), west of Invercargill near Oreti Beach. While much of that specialised knowledge was lost after the European settlement of New Zealand, the use of the tree as food and medicine has persisted, and the use of its fibres for weaving is becoming more common. Rubra means red, and boy, it's red all right but right next door to it is a lovely cordyline with yellow colouring. Trees in the southern North Island and northern South Island are generally unaffected with few dead branches and no symptoms of Sudden Decline. Genotypic variation of dead leaf retention by Cordyline australis (Lomandraceae) populations and influence on trunk surface. [25], In north-west Nelson, there are three ecotypes defined by soil and exposure. As they mature, they become stunning specimen plants with tall trunks, topped by pineapple like tufts. In the Stewart Island region, it is rare,[42] growing only on certain islands, headlands and former settlement sites where it may have been introduced by muttonbird collectors,[43] while on the Chatham Islands it is also largely "a notable absentee". Harris, W. (2004). The greatest number of dead trees (18 to 26 percent) was recorded around Auckland.[65]. [68], In traditional times, Māori had a rich knowledge of the cabbage tree, including spiritual, ecological and many practical aspects of its use. Tips for planting and caring for Cordyline Plants. [12] It does not do well in hot tropical climates like the Caribbean, Queensland, Southeast Asia or Florida. Rees-George, J., Robertson, G. I., & Hawthorne, B.T. [53] Each inflorescence bears 5,000 to 10,000 flowers, so a large inflorescence may carry about 40,000 seeds, or one million seeds for the whole tree in a good flowering year—hundreds of millions for a healthy grove of trees. [30] The type locality is Queen Charlotte Sound. With ist unusual and palm-like appearance cabbage trees are a feature of the NZ landscape. Fine specimens are found along the upper Whanganui River. It does well in pots and tubs. However, it is more probable that the name arose from it being moved around its native land as a domesticated plant. Like terminal cuttings, set the suckers into containers filled with a mixture of potting soil and horticultural grit to establish well-drained soil. How to Propagate Cordyline Australis. Cordyline australis flower in summer, the picture above is from a young Cordyline australis and this is the first time it has flowered. Water the suckers as needed; they like moist, but not completely wet, soil. After the first flowering, it divides to form a much-branched crown with tufts of leaves at the tips of the branches. Easily grown from fresh seed (seedlings often spontaneously appear in gardens from bird-dispersed seed), emergent shoot, stem and even trunk cuttings. Several cordyline species are native to Australia and at home in native foliage or rainforest gardens. Populations of C. australis were decimated in some parts of New Zealand because of Sudden Decline. This variation can alter the overall appearance of the tree, canopy shape and branch size, the relative shape and size of the leaves, and their colour and stiffness. The nectar produced by the flowers contains aromatic compounds, mainly esters and terpenes, which are particularly attractive to moths. Cordyline do not usually flower and set seed until they are 15 to 20 years old. [60] Juice from the leaves was used for cuts, cracks and sores. If you are planting it outside, adding a layer of mulch around the base of your cordyline plant; doing so will help to retain moisture and will also prevent weeds that could potentially drain the moisture the plant needs from growing. Cordyline australis is the tallest of New Zealand's five native Cordyline species. [84], Cordyline 'Ti Tawhiti' was "the subject of an intense discussion amongst the leading botanists of New Zealand at a meeting of the Royal Society ... in Wellington 100 years ago. [14][36][37] Each tribe had names for the tree depending on its local uses and characteristics. In: Oates, M. R. ed. Eventually the tissue in the centre of the stem rots away and a cavity forms along its entire length. [41], Cordyline australis is a light-demanding pioneer species, and seedlings die when overtopped by other trees. Most of these trees will slowly die out because livestock eat the seedlings and damage the trunks and roots of adult trees. Cornish Palm tree / Cordyline australis at Newquay, Cornwall, set against bright blue summer sky. It was saved from extinction because its dwarf form found favour with gardeners and it came to be known as Cordyline 'Kirkii' recording the interest Thomas Kirk had in the plant. [28] Europeans used the plant to make alcohol, and the often fearsome brews were relished by whalers and sealers. The leaves were "[61] As the native birds have vanished from much of New Zealand with the clearing of forests, it is now flocks of starlings which descend upon the fruit. This cultivar is a showy and vigorous plant with very dark reddish-bronze sword-like leaves. Each branch may fork after producing a flowering stem. [68] Once the trunk has been damaged by animals, it seldom heals and the wounds get bigger over time. Terribly well known spiky exotic from New Zealand. To grow well, young plants require open space so they are not shaded out by other vegetation. Astelia species and Collospermum often establish in the main fork of the tree, and one tree can host several species of native orchid. As mention, as long as the right conditions are met, cordyline is pretty easy to grow and requires very little maintenance and care. Tender species make good house or … [4][14] The fruit is a white berry 5 to 7 mm (3⁄16 to 9⁄32 in) in diameter[4] which is greedily eaten by birds. This variety is evergreen and performs best when planted in a sunny position. Place a plastic bag over the pot to retain the moisture and set it in a warm, sheltered location. When a bushfire has cleared the land of vegetation, cabbage tree seeds germinate in great numbers to make the most of the light and space opened up by the flames. They are thick and have an indistinct midrib. Rabbits can be more destructive, especially during periods of drought, when they have been seen to eat through the base until a tree falls, and then eating the fallen tree completely. [17][71][72][74], Evidence of large cooking pits (umu tī) can still be found in the hills of South Canterbury and North Otago, where large groves of cabbage trees still stand. [28], Large parties trimmed the cut stems, and left them to dry for days or weeks. All the leaves were very yellow so I have cut then all down. Māori valued the narrow spiky leaves as a source of particularly tough, durable fibre. While it can deal with small amounts of shade, the ideal setting is a location that gets plenty of sunlight. A quote from Philip Simpson sums up the wide range of habitats the cabbage tree occupied in early New Zealand, and how much its abundance and distinctive form shaped the impression travellers received of the country: "In primeval New Zealand cabbage trees occupied a range of habitats, anywhere open, moist, fertile and warm enough for them to establish and mature: with forest; around the rocky coast; in lowland swamps, around the lakes and along the lower rivers; and perched on isolated rocks. It’s important to note, however, that while Cordyline does like plenty of light, you should avoid setting it an area that gets direct sunlight; otherwise, the vibrant coloring of the leaves will fade. The right conditions can reduce the first flowering age to 3 years (Havelock North, 2015 mast year). Simpson reports that the names highlight the characteristics of the tree that were important to Māori. [17] In the far north of New Zealand, C. australis can be distinguished by its larger heavily branched tree form, narrower leaves and smaller seeds from C. obtecta, the Three Kings cabbage tree,[34] its closest relative. (1833), Prodromus Florae Norfolkicae: 29. It should be placed in a warm location that receives plenty of sunlight; a greenhouse would be the most suitable location. A favourite is Cordyline 'Rubra'. Naturally a tall single trunked, many branched tree, here in the UK Cordyline australis rarely reaches giant proportions as, inevitably, it will be cut back by cold. [45] This form resembles that found in the far south of the South Island, suggesting that they are both adapted to cold conditions. Flowering takes place on these palms after about 15 years at which point the growing tip splits to form two stems. Cordyline is a unique plant that belongs to its very own genus. When the leaves do break down, they form a fertile soil around the tree. Remove any dead plant matter from the cutting and allow it to air out before recovering. Cabbage tree leaves contain oils which make them burn readily. Some of the growing tips have changed from making leaves to producing inflorescences for the coming spring, and around these, two or three buds begin to produce leaves. Tricolor Hawaiian Ti Plant, cordyline fruticosa, used for thatching and clothing. To propagate cordyline from terminal cuttings, remove a stem from the plant that contains a terminal bud or that features a growing point on its tip and a collection of buds on the stem. As previously mentioned, cordyline does not need a lot of pruning. Prior to tying it up, make sure that the plant is fully dried; if any moisture is on the leaves before you tie it up, there’s a good chance that they will rot. [26], Wharanui grow to the west of the North Island's main divide. The strong framework of the inflorescence can easily bear the weight of heavy birds like the New Zealand pigeon, which was formerly the major disperser of the seeds. In western Northland and Auckland, a form often called tītī grows. Before it flowers, it has a slender unbranched stem. Bees use the nectar to produce a light honey to feed their young and increase the size of the hive in the early summer. Wellington. The stigmas are short and trifid. Cordyline likes a lot of light. [9] The kōata, the growing tip of the plant, was eaten raw as a blood tonic or cleanser. In New Zealand and overseas, hybrids with other Cordyline species feature prominently in the range of cultivars available. We may get paid if you buy something or take an action after clicking one of these. The latter two forms extend down the West Coast, with the lax-leaved forms growing in moist, fertile, sheltered river valleys while the bluish-leaved forms prefer rocky slopes exposed to the full force of the salt-laden coastal winds. In many Northland parks, cabbage trees from the central North Island were growing and flowering within metres of natural forms. Makes a great feature plant in patio pots or as part of a mixed herbaceous border. [50] The flowers produce a sweet perfume which attracts large numbers of insects. [20], The cabbage tree's year begins in autumn among the tight spike of unopened leaves projecting from the centre of each tuft of leaves. Possums tend not to eat the leaves of the tree, but are very fond of eating the sugar-rich flowering stalks as they emerge. [24], In Otago, cabbage trees gradually become less common towards the south until they come to an end in the northern Catlins. [47] In modern New Zealand, cabbage trees usually grow as isolated individuals rather than as parts of a healthy ecosystem. Often the growth layer dies and the injuries may lead to bacterial or fungal infections that spread into the branches until the canopy too begins to die. [4][9][14][15], The long narrow leaves are sword-shaped, erect, dark to light green, 40 to 100 cm (16 to 39 in) long and 3 to 7 cm (1 to 3 in) wide at the base, with numerous parallel veins.
