This plant is both pretty and deadly. So much so in fact that just brushing against it can cause serious irritation to your skin. Many Australians have burned these trees to clear the threat not realizing that inhaling the fumes is actually more dangerous. Pets have died from eating these leaves and websites warn against the use of this plant’s spikes as toothpicks. I’m sure there are some amazing stories there. Every part of this plant is poisonous, from the root, stem and leaf to the flower.
