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. Striking flower spike. The single stemmed trees then develop branches and flower even more prolifically. It is absent from much of Fiordland, probably because there is no suitable habitat, and is unknown on the subantarctic islands to the south of New Zealand, probably because it is too cold. Cordyline do not usually flower and set seed until they are 15 to 20 years old. Harris, W. (2003). Adding drama year-round with its bold color and tropical look, this beautiful palm introduces substance to the garden. If the plant is exposed to cold temperatures before it is established, it likely will not survive.

While coryline don’t specifically require a highly nutritious soil to thrive, to ensure the plant is as healthy as possible when planted in the ground, apply an evenly balanced slow release fertilizer during the start of the spring season. [63], There are nine species of insect only found on C. australis, of which the best known is Epiphryne verriculata, the cabbage tree moth, which is perfectly adapted to hide on a dead leaf. Salmon J. T. (1973). [24], Tarariki are found in the east of the North Island from East Cape to the Wairarapa. In parts of the Wairarapa, the trees are particularly spiky, with stiff leaves and partially rolled leaf-blades. Most are shorter than Cordyline australis; are clump forming; and have tall clusters of fragrant, white-to-pale lilac flowers in summer. The bracts which protect the developing flowers often have a distinct pink tinge before the flowers open.

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. Affected trees usually suffer total defoliation within 2 to 12 months. [70], Other mammals can be destructive.

Cordyline can crow in various types of soil, including clay, sand, loam, and chalk; it just needs to be well drained, yet moist, and relatively fertile. Cordyline stricta, also known as the slender palm lily, and C. petiolaris, which is the broad palm lily, are native to the rainforests of eastern Australia. Absent from much of Fiordland, it was probably introduced by Māori to the Chatham Islands at 44° 00′S and to Stewart Island at 46° 50′S. It provided durable fibre for textiles, anchor ropes, fishing lines, baskets, waterproof rain capes and cloaks, and sandals. Container-grown plants should be fed with liquid fertilizer on a monthly basis during the growing season, which usually begins in late spring and ends in late summer. [9][15] Good flowering seasons occur every few years only. Advertiser Disclosure: Few examples of this former abundance survive today—such areas were the first to be cleared by farmers looking for flat land and fertile soil. Full sun. Dracaena indivisa). Flowering spikes of Cordyline australis in Cornwall, UK. [41], Cordyline australis is a light-demanding pioneer species, and seedlings die when overtopped by other trees. The greatest number of dead trees (18 to 26 percent) was recorded around Auckland.[65]. With a sharp knife, cut the new stem from the mother plant at the base of the new stem. Different trees were selected for their degree of bitterness, which should be strong for medicinal use, but less so when used as a vegetable. "[33] Forster may have been referring to the cabbage palmetto (Sabal palmetto) of Florida, which resembles the Cordyline somewhat, and was named for the cabbage-like appearance of its terminal bud. [38], The stems and fleshy rhizomes of C. australis are high in natural sugars and were steam-cooked in earth ovens (umu tī, a large type of hāngi) to produce kāuru, a carbohydrate-rich food used to sweeten other foods. Seedlings often have leaves with red-brown pigmentation which disappears in older plants, and this coloration becomes increasingly common towards the south. 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.

They can infest young trees but seldom damage older trees, which lack the skirt of dead leaves where the parent moths like to hide. When young, tītī are generally very spindly, and are common in young kauri forests. [24] When growing in the open, tītī can become massive trees with numerous, long thin branches and relatively short, broad leaves.

[44], Generally a lowland species, it grows from sea level to about 1,000 metres (3,300 feet), reaching its upper limits on the volcanoes of the central North Island, where eruptions have created open spaces for it to exploit, and in the foothills of the Southern Alps in the South Island, where deforestation may have played a part in giving it room to grow. 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". If you plan on growing it indoors, a spot near a window or a greenhouse that gets plenty of sun would be ideal.

It's these new stems that I utilize to create new plants. Cordyline australis. [28] They reappear on the south coast at Waikawa, Southland, but they are not the wharanui type. [71][72] As well as stems, the rhizomes—extensions of the trunk below the surface of the ground shaped like enormous carrots—were also dug up to be cooked. However, it is more probable that the name arose from it being moved around its native land as a domesticated plant. Place a plastic bag over the pot to retain the moisture and set it in a warm, sheltered location. The tree can also be found in large numbers in island restoration projects such as Tiritiri Matangi Island,[8] where it was among the first seedling trees to be planted.[9].

The changes in shape—leaves getting narrower and more robust from north to south and from lowland to montane—suggest adaptations to colder weather. The nectar produced by the flowers contains aromatic compounds, mainly esters and terpenes, which are particularly attractive to moths. [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. 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. 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. Electric Pink grows 45 feet tall and wide. In many Northland parks, cabbage trees from the central North Island were growing and flowering within metres of natural forms. The climate there is an extreme one, with hot, dry summers and cold winters. The Royal Horticultural Society gave Cordyline australis their prestigious Award of Garden Merit in 1993. [4] Hybrids with C. pumilio and C. banksii also occur often where the plants are in close vicinity, because they flower at about the same time and share the chromosome number 2n=38, with C. Native to the Pacific Islands and some parts of Southeast Asia, there are about 15 species of this evergreen perennial. [23] In eastern Northland, C. australis generally has narrow, straight dark green leaves, but some trees have much broader leaves than normal and may have hybridised with the Three Kings cabbage tree, C. obtecta, which grows at North Cape and on nearby islands.
