Bear's breeches, or Acanthus mollis, is listed as a plant that can grow under Eucalyptus where many plants won't grow. This article will help with plant care:

Watering it sufficiently will be important because eucalyptus trees absorb a huge amount of water from the soil around them.

Acanthus White Water

I live in RI where I believe it to be zone 5. Will this plant survive if I bring it indoors in the fall?

ANSWERS

This plant is hardy in zones 7-10.

You should be able to winter over indoors. It will die back in the late fall or early winter.

That sounds like powdery mildew. You can remedy this with neem oil, rosemary oil, garlic oil, and/or lavender oil. Here is an article for more information: https://www.gardeningknowhow.com/plant-problems/disease/powdery-mildew-homemade-and-organic-remedies.htm

Unknown Plant

Hi there, I live on the Gold Coast in Queensland and found an unknown plant growing in the garden (see attached picture). It looks similar to Acanthus Mollis but has some serious looking thorns on its stems. Any ideas as to its common/botanical name?

ANSWERS

Acanthus literally means thorns and there is speculation that it is responsible for the Crown of Thorns in Christendom. It could be you are accustomed to cultivars that don't have thorns but I think you are spot on with your genus guess. It is invasive in some areas and spreads by underground rhizomes.
