Comm<strong>on</strong> name: Cocos Palm Latin name: Syagrus romanzoffiana<br />

FAMILY: ARACACEAE<br />

ORIGIN:<br />

Noxious Weed Category: W5 (Envir<strong>on</strong>mental Weed)<br />

Descripti<strong>on</strong><br />

Habit: Tree to 15m with single, straight trunk, frequently planted in municipal areas and private yards.<br />

Leaves: Large (to 3m), whorled and compound with many l<strong>on</strong>g leaflets. Seedlings do not have divided<br />

cotyled<strong>on</strong>s as in Bangalow Palm (Arch<strong>on</strong>tophoenix cunninghamiana). Flowers: Cream to white in large,<br />

showy panicles. Fruit: is an orange, fleshy drupe (ie single seeded) 10mm in diameter.<br />

Ecology: Similar to that of Canary Island Date Palm (Phoenix canariensis). Well suited to <str<strong>on</strong>g>the</str<strong>on</strong>g> tropics and<br />

sub-tropics, it grows readily from seed which often originates from municipal and private amenity plantings.<br />

Large numbers of seedlings usually germinate beneath parent trees and particularly where seed has<br />

‘rafted’ into piles al<strong>on</strong>g stream banks. Dense stands are uncomm<strong>on</strong>, but large numbers can establish in<br />

forest types usually inhabited by o<str<strong>on</strong>g>the</str<strong>on</strong>g>r endemic palms such as Bangalow and Cabbage Palm (Livist<strong>on</strong>a<br />

australis).<br />

Dispersal: Seeds are eaten and spread by birds, flying foxes, possums etc.<br />

C<strong>on</strong>trol<br />

As for many woody <strong>weeds</strong>, c<strong>on</strong>trol is best undertaken as early as possible while <str<strong>on</strong>g>the</str<strong>on</strong>g> plant is as small as<br />

possible. HAND: Seedlings can be hand-pulled, but young plants quickly develop a str<strong>on</strong>g, fibrous root<br />

system making hand-pulling difficult. Juveniles can be chipped out. CHEMICAL: Juveniles can be cut close<br />

to ground level and immediately painted with undiluted glyphosate (eg RoundUp Biactive). Larger palms<br />

can be treated by chiselling or drilling around <str<strong>on</strong>g>the</str<strong>on</strong>g> trunk close to <str<strong>on</strong>g>the</str<strong>on</strong>g> ground 100mm apart and filling with<br />

2mm of undiluted glyphosate per hole.<br />
