Discussion | Veronica catenata seems to be a relative of V. anagallis-aquatica that is more cold-adapted, as seen in Europe (R. Götte 2007), and native to the flora area. Although no specimens were seen it may be found in Alaska, Connecticut, and Kentucky. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Veronica spicata is widely distributed in horticulture and a multitude of cultivars is available. Some specimens may also be derived from a related species, V. barrelieri Schott ex Roemer & Schultes, differentiated from V. spicata by glabrous calyx lobes, and in its typical variety, by eglandular pubescence. Another closely related species, V. incana Linnaeus, has a dense white woolly indumentum and is native to northern Asia and eastern Europe; it has not escaped from cultivation in the flora area.
