Discussion | Veronica filiformis is self-incompatible. In the flora area, plants seldom produce capsules; it is dispersed by stem cuttings. The species is native to subalpine meadows in the Caucasus and northern Turkey. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
In the flora area, Veronica undulata was introduced near ports (Mobile, Alabama, and Portland, Oregon) before 1900 via ship ballast from trade with Asia, did not spread much, and may not have persisted. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
