A North American perennial with dark violet flowers in clustered upright spikes. Easy from seed (which is how I happen to have it).
Although these short lived, seeding perennial Verbena are very popular in dryer gardens, it is unlikely to succeed here. Plants of the World Online says: "The native range of this species is Canada to U.S.A. It is a biennial or perennial and grows primarily in the temperate biome." Writing in JRHS in 2016, Derry Watkins says: "By contrast, North American verbens, such as Verbena hastata (from the East coast of the USA and Canada), all seem to hold their flowers on vertical spikes. Growing to 1.5m (5ft) or taller, its clusters of upright flower spikes are utterly unlike the flat topped V. bonariensis, more like a handful of pencils; vertical accents of colour. Rings of tiny flowers open from the bottom of the spike gradually moving upward to leave behind the pencil-shaped seedheads that stand well into winter, providing food for birds." |
