Veronica lavaudiana -DA-

Small shrub of the Plantaginaceae family, Veronica lavaudiana is a strictly endemic species localized to the Banks Peninsula on the South Island of New Zealand, where it is classified as declining and considered threatened. It grows on open rocky outcrops and exposed cliffs, in the sunniest and windiest habitats, where plant competition remains limited.

Spreading and low shrub, its prostrate to semi-erect branches reach 10 to 30 cm in height. The leaves, obovate to almost round, thick and leathery, measure 12 to 25 mm long; they are dark green, slightly glaucous, with crenate margins. Their bright carmine-red edging, sharp and precise, following each crenature of the blade, is the most immediately striking feature of the foliage. The branches are finely pubescent, a detail visible under a magnifying glass.

The flowers, gathered in compact clusters of 2 to 4 cm, are pink in bud then whiten after pollination; the stamens with white filaments and yellow anthers animate them with a slight contrast. In its natural environment, its flowering extends from October to November, sometimes until January.

The species is primarily threatened by the invasion of its habitat by European gorse (Ulex europaeus). In cultivation, it multiplies easily by semi-hardwood cuttings or fresh seed; it requires very well-drained soil, full sun exposure, and good air circulation, as it is sensitive to fungal diseases and poorly tolerates high atmospheric humidity.
