Coming up Cabbages: a few words on Cordylines
February 11, 2011 § 21 Comments
Ireland is often a green and misty land (although less greener than usual during this cold winter). And one of the things that surprises visitors is the sight of “palm trees” incongruously raising their mop tops through the Celticky fog. They decorate our towns and suburbs, they are blasted by the salt air on our seafronts, and they are often seen in pairs guarding the entrances to farmhouses. But, they are not palm trees at all: they are the New Zealand native, Cordyline australis. They enjoy the common name of “cabbage tree”, supposedly because settlers in New Zealand found the young leaves to be a tolerable substitute for cabbage.
Cordylines are much loathed. Partly it is because of the occasional and near-indestructible leaves that the trees shed (dried, they make great kindling) and partly — I think — it is because they have both lowbrow and suburban associations. It’s not unusual to see them sprouting out of a jolly carpet of summer bedding. In other words, in the eyes of a certain kind of refined gardener, the cabbage tree is a shining example of bad taste.
One of the first things that cordyline-haters do upon inheriting one in a garden, is to hack it down to the ground. The trees are unfazed by such insults, and regenerate eagerly, popping out several stems in the place of the previous single one. Good for them. This winter and the last, though, have not been kind to cordylines, and the inland parts of this country are littered with their still-standing, but mummified, corpses. I fear they may not rise again to annoy the better classes of gardeners.
Where I live, however, all these misunderstood New Zealanders are in the pink of health. Our barometer has not dipped lower than minus 5 degrees Centigrade (23 F), whereas elsewhere in Ireland, the temperature was ten or more degrees colder. In our mild climate, the cordyline blooms every year. The angular panicles are crammed with creamy flowers, which open in late spring, and go on for weeks. The scent — strongest in the evening — is powerful and lily-like. For me it is one of the exhilarating fragrances of early summer. Bees would seem to agree. They love the flowers, and work them all day. And in the autumn and early winter the thousands of ivory-coloured berries, which are full of fats, help to keep birds alive. My neighbours’ tree across the road is a busy re-fuelling point for blackbirds, thrushes, starlings, blackcaps and wood pigeons.
If you don’t like cordylines, or if they don’t do well in your colder area, then — as we say here in a very self-righteous voice — I’m sorry for you. And you’re not likely to be interested in knowing that they belong to the same family as asparagus, Asparagaceae, a clan that also includes lily-of-the-valley and hosta.
