Hello,

I am a garden question responder and can’t address your legal issues. However, I can provide you with accurate science-based information on milkweed.

There are several kinds of plants called milkweed. Common milkweed, scientific name Asclepias syriaca, is a plant native to North America. By definition it cannot be ‘invasive’. It can be an aggressive plant that needs to be managed in some gardens. See the details here, and compare what you have to the pictures.

The common milkweed is not on any invasive plants list in the USA. This statement from the Monarch Joint Venture Organization explains more-

And this link lists milkweeds best for each region. There are several for the northeast, and perhaps your Association wouldn’t have a problem with a different choice-

If you still need advice on the legal issues between tenant and association, please respond and I will try to find an Extension resource to help you.

Thank you.
