Perennial of the Plantaginaceae family, this subspecies is widely spread in Central and Southern Europe, from the Iberian Peninsula to Ukraine and Asia Minor. It occupies dry to mesophilic lawns, sunny edges, grassy embankments, and calcareous meadows, from the plain level to the lower mountain stages.
It forms upright and vigorous clumps, with ascending stems that can reach 30 to 40 cm in height, adorned with oval to oblong, toothed, medium green leaves, slightly pubescent. The habit is frankly upright and the vegetation dense, forming tight clusters particularly neat at the time of flowering.
The flowers, gathered in elongated and very dense lateral clusters, are bright blue to intense blue-violet, with a well-marked white eye and fine dark veins on the petals. Their hue is one of the deepest and most saturated that can be found among large European veronicas.
In its natural habitat, its flowering extends from May to July. In cultivation, it generally blooms in May-June and can be stimulated by pruning after flowering.
It adapts to any ordinary well-drained soil in full sun or light partial shade, and is robust and undemanding. It is suitable both in large rock gardens and as a border of massifs.
