Fields of Arum lilies

Driving through the south west of WA in the spring, the fields of Arum Lillies are breathtakingly beautiful. Growing with wild abandon absolutely everywhere, they create displays that must surely rival Wordsworth’s Daffodils. Beautiful, but not wanted in WA.

A perfect specimen of a flower – if only it was wanted


The Arum Lily, from South Africa,was introduced as a plant to glorify our gardens. The flowers are beautiful and indeed, glorious, albeit poisonous to both humans and animals. However, that’s not where the real problem lies. No-one could have anticipated how rampant it would become once it escaped the confines of the household garden. It’s now classified as an invasive pest, and you only have to drive through the Margaret River region in the Spring, knowing it’s not a native, to understand why

The 2011 bushfires that ravaged the area around Margaret River had an additional devastating consequence. The open soil left in the wake of the fires provided ideal conditions for the lilies to multiply, dare i say it, faster than wildfire!

In open areas, birds are spreading the seeds, and individual clumps are sprouting up, only to later multiply into visually stunning fields of toxic green and white. They’re taking over the land faster than our our own natives can regenerate, and are consequently making it difficult for the native bush to compete.

This years clumps become next years fields

Despite an eradication program, the banks of Arum lilies don’t seem to be diminishing. One day, hopefully they’ll be gone, but until that day, with reservations – I’ll still enjoy the stunning (albeit hopefully temporary) display they create in the spring.
