A perennial of the Plantaginaceae family, this variety of Veronica schmidtiana shares the Japanese origin of the type species, growing on rocks and rocky slopes at altitude in the mountains of Honshu. It differs from the type by its foliage deeply cut into narrow, linear lobes, giving it a finely chiseled, almost thread-like appearance, very different from that of the type form.
It forms a compact and dense tuft, 6 to 12 cm in height, with a rounded and well-ordered habit. This cut foliage, of a dark green, constitutes in itself a remarkable ornamental feature, even outside of flowering.
The flowers are a fairly strong lilac-mauve, slightly streaked, gathered in short spikes that emerge above the tuft. The long white stamens clearly exceed the corolla, giving the spikes an airy and ethereal appearance. The hue here is more pink-mauve than the type, which leans more towards blue.
In its natural habitat, its flowering extends from June to August depending on altitude. In cultivation, it generally blooms in June-July.
It requires a very well-drained, gravelly soil, a sunny exposure, and protection against stagnant moisture in winter. Like the type species, it readily reseeds near the mother plant.
