Cordyline obtecta ‘Albatross’ (Superstar)

A New Zealand selection raised from ‘Falcon’

Gordon Scott selected ‘Albatross’ in Whenuapai, New Zealand, in 1999 from seedlings raised after open pollination of ‘Falcon’; the pollen parent is unknown. He chose the seedling for its broad, glossy purple-red foliage. Tissue-culture propagation began in Hastings in 2005. The selection therefore originated within cultivated nursery stock.

The cultivar received United States Plant Patent 23,715 under the older botanical placement Cordyline baueri. That name is now treated as a synonym of C. obtecta, which places the cultivar with Cordyline obtecta.

The species behind the cultivar is native to Norfolk Island and northern New Zealand, including the Three Kings Islands.

How to care for Cordyline obtecta ‘Albatross’ (Superstar)

Light for the deep purple-red crown

Place Superstar directly by a bright south-, west- or east-facing window. Its broad dark purple-red crown is best developed under strong daylight and can be acclimated to several hours of direct sun. The full crown needs to see the window, and established foliage may receive several hours of direct sun after acclimation. Shield a newly moved plant from abrupt midday heat. In shade, leaves lengthen and soften and the trunk grows towards the light. The dark pigment is inherited and should not be forced through drought or harsh sun.

Soaking the roots beneath a broad dark rosette

Use pot weight and a check several centimetres down to water Superstar. When the upper layer is dry, saturate the complete mix and empty any collected runoff. The plant tolerates modest dryness. A neglected, shrunken root ball causes root and leaf damage. Persistent wetness is especially risky. A dark crown in hot sun, a deep root-filled pot and terracotta accelerate drying; a cool room or newly upsized container slows it substantially.

Drainage for the heavy purple-red crown

Choose a deep but only modestly sized pot for Superstar, filled with a freely draining blend of potting substrate, bark and pumice, lava or perlite. Its anchoring roots should be able to grow down without being pressed into dense material. Keep the crown above the mix, use a proper drainage hole and rinse visible salt deposits away before they begin damaging the leaf tips.

Winter protection for Superstar

Keep it at approximately 10–26 °C, allowing a bright, relatively cool winter around 8–15 °C if the root ball is not kept wet. A container-grown Superstar should remain above approximately 5–7 °C and out of contact with freezing panes. Bright cool conditions are acceptable when watering is reduced. Sudden alternation between cold draughts and heated air can mark the broad dark leaves, so change its position gradually.

Fresh air around wide leathery blades

Average room humidity suits Superstar; a humidifier is normally not required. The crown benefits more from clear space and gentle air exchange, especially after a shower. Avoid misting the broad strap-shaped leaves as a routine, since water and minerals can collect where they meet the trunk.

Nutrition for a broad dark crown

Give Superstar a complete balanced fertiliser at no more than half strength while it is growing, leaving roughly four to six weeks between doses. Match the dose to the available light, temperature and nutrients already present in the mix. Winter feeding can continue lightly when the plant stays warm and produces new leaves. Rinse the pot periodically because excess salts first show as brown leaf tips.

A heavier pot for a 1.5-metre specimen

Give Superstar a new container only after its deep roots have filled the existing one or the substrate no longer absorbs water evenly. The next pot should be 3–5 cm wider and heavy enough to support the crown. Disturb the central roots as little as possible, loosen only tightly circling roots at the edge and return the trunk to exactly the same level.

Managing an expanding fountain-shaped crown

The developing trunk should stand without a stake once rooted; use a heavy container if the crown becomes top-heavy. Remove spent lower leaves cleanly and shorten the trunk only when a permanent change to a branched, reshooting form is acceptable. Turn the container slowly as new leaves harden, because an established lean is difficult to correct without bending the trunk.

Handling Superstar’s broad outer leaves

Remove only dead lower growth and leave dry bases until they loosen. Dust can be rinsed away or wiped with several leaves supported together; never pull individual leaves through a tight grip.

Checking the fountain-shaped crown of Cordyline obtecta ‘Albatross’ (Superstar)

Dark purple-red leaves develop pale or greenish areas

Superstar should have broad, glossy dark purple-red foliage. A gradual greener cast in new growth usually points to insufficient light, while dry bleached patches on the window-facing side fit sun scorch. Increase light gradually if the new growth is firm, but move the plant away from hot glass if damage is crisp and localised. Uniform yellowing with softness calls for a root and temperature check.

Wide sword leaves fold or split across the blade

The fountain-shaped rosette needs clearance. A straight crease or tear usually comes from packaging, handling or a leaf pressing against glass and will not spread. Support the new crown and leave partly green blades attached. Soft irregular lesions or a damaged central spear are not ordinary mechanical wear.

The fountain opens out and leans towards one side

One-sided light draws the wide leaves away from the centre and can make the heavy rosette unstable. Increase overhead light gradually, rotate the pot and make sure the root ball is anchored. If the base itself is bending or soft, stop rotating and inspect for stem damage.

The central leaves collapse after cold exposure

The growing point is less replaceable than a damaged outer blade. Keep the plant warm, remove only tissue that is fully dead and watch for a firm reshoot below the injury. A brown, soft centre or foul ooze strongly suggests active crown or stem decay. Remove affected tissue promptly, cutting back to firm, clean tissue.

Pet safety for Superstar

Cordyline foliage can contain saponins, so treat Superstar as toxic to cats and dogs. Chewing may cause vomiting, drooling, poor appetite or unusual tiredness. Keep the broad leaves and shed foliage out of reach, and contact a veterinarian after any known ingestion.

The names ‘Albatross’, Superstar and obtecta

‘Albatross’ is the cultivar denomination, while Superstar is the selling name used for the same plant.

The Latin epithet obtecta means concealed or covered. It refers to the flower cluster being partly enclosed by the surrounding leaves.
