nettle

In the midst of a mass – or "smack" – of Pacific sea nettles, Mr Pace coated any skin not covered by his wetsuit with petroleum jelly to protect himself from stings.

When questioned why he did that, he said: "The grass had been cut and there were nettles. But I know that's no excuse."

Leafy greens and herbs: arugula, spinach, beet greens, mustard greens, radish tops, kale, dandelion, nasturtiums, fennel fronds, nettles, lovage, microgreens.

But he said not much had happened since because politicians were too afraid to grasp the nettle.

He said the government would "finally grasp the nettle on social care reform" but that it "would take time" to devise a model fit for the future.
