Perennial hybrid of the Saxifragaceae family, 'Dawn Frost' belongs to the Kabschia saxifrages group, Porphyrion section. It was obtained in the Czech Republic in 1990 by Jan Burgel, from a sowing of Saxifraga × anglica 'Winifred', another cultivar with pink flowers. It is therefore a recent hybrid within a group whose some representatives have been cultivated for over a century.
The plant forms a dense and tight cushion, with dark green foliage, sometimes with brownish hues on exposed parts, not exceeding 5 to 8 cm in height. The rosettes are compact, with small and rigid leaves, typical of alpine cultivated Kabschia.
The flowers, borne on very short peduncles, are bright pink to soft pink, with five well-rounded petals and contrasting golden stamens. They abundantly cover the cushion to the point of sometimes completely masking the foliage. In cultivation, flowering occurs from late winter to early spring, depending on the climate, from February to April.
Like all Kabschia, it requires perfect drainage and good air circulation, essential conditions to prevent rot. It is cultivated in well-drained rock gardens, in crevices, or planted in tufa, a poor substrate that promotes a particularly compact habit. Protection against prolonged winter rains is recommended but not essential in all climates.
