Horticultural selection of Scutellaria alpina, a perennial from the Lamiaceae family, this form is distinguished by a floral coloration quite unusual in the genus. Like the type species, it shares the same European mountainous origins and the same cultural requirements.
It forms upright clumps 10 to 20 cm in height, with well-branched stems bearing oval, crenate leaves of a medium green, slightly rough texture, arranged in opposite pairs. The general habit is similar to that of the type species, bushy and generously flowered in full season.
The bilabiate flowers feature a pale yellow to sulfur yellow lower lip, and an upper lip of a delicate pinkish lilac, sometimes slightly more pronounced depending on the individuals and light conditions. The light green bracts, clearly visible between the flowers, enhance the impression of softness and discretion of the whole. This unusual combination of yellow and pinkish lilac is the most distinctive feature of this selection within the alpina group, and clearly sets it apart from white or purple forms.
In its natural habitat, the flowering of the type species extends from July to August. In cultivation, 'Flava' blooms from June to August depending on exposure.
It should be noted that the exact status of this cultivar name is not documented in the main horticultural references consulted; it could be a garden selection or a natural form brought into cultivation. It is grown in full light, in well-drained and rather poor soil, in a sunny rock garden or wall.
