Cultivar selected from Geranium cinereum, a perennial of the Geraniaceae family native to the Pyrenees and northern Spain. This cultivar, obtained by Alan Bloom in Bressingham in the 1970s, is one of the most widespread rock garden geraniums in European gardens.
It forms a compact and dense cushion 10 to 15 cm in height, with finely cut gray-green foliage, semi-evergreen depending on the winters. The floral stems, slender and spreading, hold the flowers well above the foliage.
The flowers are large relative to the size of the plant, with rounded petals slightly overlapping, of a pale lilac pink traversed by a tight network of purple-magenta veins intensifying towards a very dark, almost black-purple central eye. This combination of a light veined background and a deeply colored heart is the immediate hallmark of this cultivar, more contrasted than the type species.
Its flowering in cultivation extends from May to September, with remarkable generosity and continuity for a plant of this size.
It requires very well-drained soil, poor to moderately rich, in full sun. It perfectly withstands summer drought and limestone. A light pruning after the first wave of flowering encourages reblooming. Ideal plant for rock gardens, walls, and containers.
