Verbena bonariensis blooms the first year from seed. The tall stems are topped with clusters of rosy-purple flowers that attract hummingbirds and butterflies. It's a host plant for the Common Buckeye butterfly. Verbena bonariensis is hardy in zones 7-10, but it often overwinters in my zone 5 garden. Grow it as a self-sowing annual in colder regions. It's very vigorous and may be considered invasive in warm zones.
