Would like details on bear breeches near eucaplyptus.
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.
I live in RI where I believe it to be zone 5. Will this plant survive if I bring it indoors in the fall?
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.
What are the white spots and what do I need to do about them?
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
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?
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.
Acanthus mollis: to restrict its width growth, can it be planted in a 5 gallon container with the bottom cut out? It is for an area only 30" wide.Any other suggestions?
What I would do would be to plant an empty pot in the ground, and put the plant in a restricted container inside of this pot, so that it can be removed. This will take diligent trimming of the top and the roots each year, so this design will help it to be much easier for you. It will combine the aspects of container, and in ground gardening, so that you can control size, while still maintaining a professional appearance.
I recently purchased a Thunbergia grandiflora vine. It will remain in a pot since I live in zone 6a. There are a lot of ants on it. Can I spray it with insecticidal soap or is the plant sensitive to such treatment? I don't want to lose it. What is the best way to control the ants? Also, when it gets too cold to remain outside, can I cut it back and overwinter it indoors in an unheated garage or in my heated basement? Overwintering care? Thanks.
Ants are naturally attracted to the flowers on your vine.

Hello! I have an Acanthus Mollis Oakleaf that I accidentally (stupidly) fed with rose food. The leaves have yellowed which at first I thought was overwatering. Plant has been in same location, same watering schedule for 6 years and has always thrived. Finally hit me as to what I did. Any tips on how to revive it? Wondering if I should cut it back and let it recover? Thanks in advance for any advice. Kathy
It will recover on its own, likely. Chelating the soil would cause more damage to the plant than it would fix at this point, and is best done while nothing is planted in the soil.
