Tall Verbena, Purple Top Vervain
(Verbena bonariensis)
Nearly every garden design book I've read mentions Verbena bonariensis. This lovely perennial blooms the first year from seed with clusters of rosy-purple flowers that attract butterflies and hummingbirds.
Verbena bonariensis is a nice companion plant for roses, ornamental grasses and all sorts of flowers. But it self-sows prolifically, which can be a problem in warm climates where it's hardy.
Verbena bonariensis is grown as an annual in the north. It's hardy in zones 7-10, but it often overwinters in my zone 5 garden.
