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.) |
