They may be one of our most famous and iconic trees – but Australian gardeners have been warned to be extra careful with one species of Grevillea.

The silky oak – or Grevillea robusta – blooms on the east coast of Australia when spring comes to an end, and is the largest and tallest tree species, up to 30 meters tall.

Anyone who comes across one of the trees on their morning walk should, however, keep a safe distance: they also drip off hydrogen cyanide.

All Grevilleas « are literally dripping nectar, much to the delight of native birds and bees, » wrote Dr. Gregory Moore from the University of Melbourne in a piece for The Conversation in which indigenous Australians once enjoyed « the sweet nectar straight from the plant or » mixed with water – the original lollipop water « .

It’s not all « sucking water » however – the nectar in a silky oak could make you sick.

“Like other Grevilleas, the silky oak contains tridecylresorcinol, which causes an allergic reaction that leads to contact dermatitis. The chemical is similar to the toxicodendron in poison ivy, ”said Dr. Moors.

He advised anyone working with silky oak « to wear gloves, a face mask, safety glasses (or face shield) and long-sleeved clothing ». .

« Hand washing and showering at the end of the day is also recommended, » added Dr. Moore added.
