You might want to contact some of the community gardens or perhaps gardening groups? There are groups that take care of gardens in public places and parks, or who have xeriscape demo gardens. Some schools might be interested, or perhaps there will be groups holding plant sales this summer/fall who would be interested in having Angelina available for sale. You can also call the Botanic Garden or the Extension people to see if they know of any groups who would be interested.

If you want to wait until fall, you can give away cuttings at our plant swap. But many of us have already discovered the good points of Angelina and have healthy patches in our yards. You'd probably get some takers, though!

Craigslist! Put it in both the "Free" and the "Farm & Garden" sections.

You can give away (and get) anything on Craigslist.

You could also post a notice on nextdoor.com. That's how I give away plants in my neighborhood.
