Many plant authorities classify it as a subspecies of the spiked speedwell Veronica spicata, under the name Veronica spicata subsp. incana. It acts as a parent to two hybrids: Veronica × czemalensis, which it forms when crossed with V. porphyriana, and Veronica × grisea, which forms when crossed with V. longifolia.
