Description
The Perennial Geranium cinereum 'Rothbury Gem' is a delightful selection of the ashy geranium, renowned for its adaptation to rocky and poor areas. It is adorned with eye-catching flowers, in cups of lavender pink veined with deep magenta. They bloom all summer, on a cushion of finely cut leaves in a slightly grayish green, as long as the soil does not dry out too much in summer. Plant this small perennial amongst rocks in the rockery, on slopes and above stone walls. Also cultivate it in a pretty pot on the terrace!
The Perennial Geranium cinereum is a member of the Geraniaceae family. It is native to grassy rocky areas in the mountains of Southern Europe to the Balkans. The 'Rothbury Gem' variety is a recent introduction, awarded in England by the Royal Horticultural Society for its ornamental qualities and performance in the garden.
'Rothbury Gem' is a herbaceous perennial with a woody base forming a cushion 12 cm (5in) in height with a minimum diameter of 30 cm (12in). Its growth is quite rapid, reaching full development in two or three years. The foliage, usually evergreen in winter, is arranged in a rosette. It is composed of 5 to 7 cm (2 to 3in) diameter leaves, deeply lobed and divided, dark green with grayish reflections, and quite soft to the touch. The flowering is renewed from May-June to September if the soil does not dry out too much, in the form of 3 cm (1in) diameter flowers, in open cups. Their color is a brilliant duo of lavender pink and magenta. They are grouped in clusters of 2 or 3, carried above the foliage by 20 cm (8in) stems. This geranium spreads slowly, without ever becoming invasive.
The Perennial Geranium cinereum 'Rothbury Gem' is a rewarding small perennial that requires little maintenance. It naturally finds its place in rockeries, at the front of perennial beds, in sunny borders, in partial shade in the afternoon, in a light, well-drained soil. It will be very effective in a flowering pot or container. It pairs well with plants with similar needs such as the Perennial Geranium renardii, the Perennial Geranium dalmaticum, ibises, statice, bushy asters, catmint and whorled coreopsis. It is an ideal perennial for mountain gardens and highly mineralized landscapes.

Planting and care
Plant the perennial Geranium cinereum Rothbury Gem in a perfectly well-drained soil, even stony and slightly chalky, not too dry in summer to support flowering. It tolerates poor soils and dreads stagnant moisture in winter, which sometimes causes its roots to rot. It requires a very sunny exposure in the morning but partially shaded in the afternoon to flower well and display a compact habit.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
