Description and General Information:
The species Geranium cinereum is native to alpine areas of the Pyrenees. The selection 'Ballerina' is perhaps the most popular. While the wild species has plain pink flowers, 'Ballerina' has pink flowers heavily veined with dark purple. Plants form low mounds, 10-15 cm high and with a spread of 30-45 cm. The leaves are small and a unique grey-green colour. The 2 cm diameter flowers are produced all season, on prostrate stems.
Cultivation:
This is a classic rock garden Geranium. It requires a well-drained site in full sun. It is not fussy about the soil pH. Once established, it is quite drought resistant. It is not bothered by deer or rabbits. It is hardy from zones 5-9.
Blooming Season:
Depending on the latitude, anywhere from May to September.
Propagation:
The straight species may be grown from seed but the cultivar 'Ballerina' must be propagated from divisions which are generally taken in spring.
