Description
The Geranium sylvaticum 'Birch Lilac', also known as Wood Cranesbill, is adapted to the damp shade of the undergrowth. It is a lush deciduous herbaceous perennial, a large spreading bush, which is adorned with abundant lilac-blue flowers with white centers in spring and summer. Resembling the meadow cranesbill, it differs from it by its slightly less dissected foliage. Ideal in cool and shady areas of the garden, in natural gardens, it is not afraid of the harsh winter cold and thrives in heavy and moist soils. This simple and grand plant will find its place in any garden.
Geranium sylvaticum 'Birch Lilac' belongs to the Geraniaceae family. It is a selection of the Wood Cranesbill, native to Europe, where it grows in undergrowth and damp meadows. This large herbaceous perennial, very hardy, forms a bushy and spreading mass of 40 cm (16in) when in bloom, with a spread of 30 cm (12in). Its growth is quite fast. It blooms in summer, from May to July, with open trumpet-shaped flowers, in a fresh and bright color, between blue and pink, illuminated by white in the center. The flowers, 2 to 3 cm (1in) in diameter, are grouped in compact cymes. The anthers are dark blue, the pistil is pink. Its basal leaves are compound with 7 lobes, deeply dissected and dentate, carried by ramified stems. The foliage is deciduous. The plant is pubescent, glandular at the top, and shows a thick and oblique stump.
Perennial and vigorous, this variety thrives in shade, it enjoys coolness and self-seeds spontaneously in humus-rich soils, forming magnificent colonies that are spectacular in the undergrowth in spring. Beautiful in the undergrowth, combine it with golden foliage; Millium effusum 'Aureum', Carex elata 'Aurea', Carex oshimensis 'Evergold', the yellow-blue contrast is, as usual, superb.

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.
