Perennial hybrid of the Saxifragaceae family, 'Peach Melba' belongs to the Porphyrion horticultural group, which includes the Kabschia saxifrages, these cushion alpines characteristic of mountain rock crevices. This cultivar has received the Award of Garden Merit from the Royal Horticultural Society, a distinction that attests to its qualities in cultivation.
The growth is slow and the habit strictly in a tight cushion, with evergreen foliage composed of small rosettes with short, medium green leaves, not exceeding 8 to 10 cm in height for a progressive spread of about fifteen centimeters.
The flowers are remarkable for their generous size given the plant's size, with flared petals of a very pale peach pink, almost pearly white when opening, with a well-visible cluster of yellow stamens in the center. This delicate, soft, and luminous shade is one of the most subtle of the group. In cultivation, flowering occurs in spring, generally in March-April.
It is cultivated in full sun or light partial shade, in a well-drained substrate, calcareous or neutral, with the roots kept fresh without excess moisture. Rock gardens, alpine troughs, or gravel gardens are also suitable, provided the drainage is impeccable. Propagation is done by cutting individual rosettes.
