Iberis taurica

Perennial of the Brassicaceae family, Iberis taurica is native to Crimea and the Pontic regions of southern Ukraine and northern Turkey. It occupies rock gardens, stony slopes, and sunny limestone cliffs, in conditions of marked summer drought.

It forms a dense and spreading cushion, woody at the base, 15 to 25 cm in height, capable of covering a generous area over the years. The foliage, evergreen, consists of small dark green spatulate leaves, which almost entirely disappear under the flowers at the time of blooming.

It is the color of its flowers that immediately distinguishes this species in the Iberis genus: the corymbs, abundant and tight, display a soft lilac pink to white, varying according to individuals and the stage of flowering. The contrast within each corymb is particularly striking: the still-closed buds, a deep purplish-brown almost chocolate, very tight at the center, sharply contrast with the open petals on the periphery, white barely tinged with pink, creating a very lively bicolor effect that renews throughout the flowering as the buds open. In its natural habitat, its flowering extends from April to June. In cultivation, it generally occurs in April-May.

It thrives in full sun, in well-drained soil, preferably limestone, poor to moderately rich, and perfectly tolerates summer drought. Its longevity and naturally compact behavior make it a reliable choice for the spring rock garden.
