The base of verbena bonariensis is not that big here, where it is not a perennial. It reseeds freely, but stays pulled out, so is not invasive. I have had some live over the winter, but the base didn't get much bigger. I'm new to growing common milkweed, but I'm thinking that sounds like a good idea. I don't know if the verbena is as tall as milkweed, though. I have a blog, where I have some photos of my verbena, but I'm not sure if I'm allowed to put a link to it here. If I find out it's OK, and you are interested, I'll give you the address. The name of the blog is A Corner Garden, and it is a Blogspot blog, so you could find it by doing a search.
I was able to locate your blog and so enjoyed visiting your gardens. What a treat! You've done a great job with sharing your gardens via your blog. I found the photos of your Verbena bonariensis and now have a much better idea of the plants structure when growing among other plants. The seeds I started this year are now planted out in my bed where I planted them among newly planted coneflowers. In front of the coneflowers I have tropical milkweed and to one side is my large planting of Salvia B&B, which the hummers adore. I'm rather limited in sunny spots so this became my first year planting site to try growing this plant.
I also recently planted a very large bed of swamp milkweed and I may try growing the Verbena bonariensis among it, too, to provide more nectaring blooms. Most of my plantings are directed toward host and nectaring plants for the butterflies and hummingbirds.
My thanks again for the invitation to visit your lovely gardens.
