This strikes me as something with the potential for anither “Crowley tried to inconvenience everyone else and instead inconvenienced himself” situation.

“Who did this,” the demon demanded, digging into the earth with a pitch fork and turning up the soil in a vain effort to get at the roots. He could have just torched the lot, but fire tended to attract a lot of attention, and he was loathed to risk taking out the wisteria and climbing roses and other vines that clambered along the walls and over the decorative trellises, not when they were doing such a good job of spitefully devouring the house one brick at a time. “Who the heaven plants mint, in the ground.”

“Anathema says lawn culture is harmful to the environment,” Adam piped up from where he was sitting on the garden wall, absently playing with a stick that currently had Dog’s full attention. “She says it’s a product of class and cultural division started by the capitalist bourge…bour…by rich people who had no need to live off the land and use it as a form of status. And it’s killing the bees. Is it killing the bees?”

Of course, the witch. Crowley paused to glare at the former Anti-Christ over his shoulder.

“No,” he said at last, driving the fork back into the ground with the help of his boot and heaving over another layer of dirt. “Well, yes. Partly.”

“What’s the other part?”

“Pesticides,” Crowley muttered darkly, pausing to wipe at his brow, surveying the damage around him. “And global warming.”

“Did you cause that?”

“What?! No! I like the earth, why would I want to see it broiled to a crisp?”

“I dunno, you like lawns.”

“I do not like lawns! I just…it’s mint. It’s an invasive species. It’ll take over everything.” And Zira won’t let me shout at them… “See, look there, it’s throttling the delphiniums, and those poor hollyhocks… If she’d wanted to get rid of the grass should could have, I dunno, planted clover or something, dug it all up and made vegetable patches, but not mint. If she wanted to use mint as ground cover she should have protected the rest of the plants with some bedding and dug in some lining. This is just spiteful.”

“You sure know a lot about plants for a demon,” the boy said, throwing the stick and sending Dog rampaging after it through the geraniums. “Why is that?”

“I find it soothing!” the demon hissed between gritted teeth, all evidence to the contrary.

Wait, I thought Mint was English?

Some mints are, but there’s also like 18 species of the damn thing and it’s got serious boundary and personal space issues.

In England you’ll find mentha growing naturally near lakes and other bodies of water and other cool, shady places, but they’re generally not a plant you want next to your house or in the ground you’re trying to cultivate unless it’s in a plant pot.
