Mangogirl, the surprise for me with this plant was that it survived winter. Most verbenas are not hardy here and people generally only grow them as annuals. In fact, Verbena Canadensis (of which the Homestead Purple is one), is the only one I know of that's rated as hardy this far north. I had planted them twice before and they didn't survive winter.
I think that after I clean up this spot I might have a lot of new plants that formed as little satellites where it formed roots at peripheral nodes. I'm not trying to root cuttings. I don't have space for many plants this huge size in my yard.
I only rooted that one cutting in fall in case these in my garden didn't come back.
