Description
Astilbe Saxosa, nicknamed the Smooth Rock Astilbe is one of the smallest species in this genus. This adorable miniature perennial plant, which develops slowly from its crown, has glossy, finely cut, slightly crisped, bronze-green leaves with a touch of red. The pure white flower spikes that turn into seashell pink are infinitely graceful, and they bloom for several weeks in summer. Plant it in a shady rockery, in moist soil with small ferns and the beautiful Saxifraga stolonifera 'Cuscutiformis', for example.
Astilbe Saxosa (synonyms Astilbe japonica 'Saxosa', Astilbe glaberrima saxosa minor) belongs to the saxifrage family. It is a relatively rare form of Astilbe glaberrima, native to Yakushima Island, Japan. It is a small rhizomatous perennial plant that forms clumps about 10 cm (4in) tall and 20 cm (8in) wide. Its deciduous foliage emerges in spring and consists of deeply divided, shiny, finely crisped leaves. The flowering period occurs between June and late August and lasts for over 2 months. The flower spikes rise 10-15 cm (4-6in) above the foliage with tiny, tousled flowers with protruding stamens grouped in spikes about 10 cm (4in) long on reddish stems. They are white when they bloom and turn pale mauve pink as they mature. The above-ground vegetation dries up in autumn.
Astilbe Saxosa is a collector's plant that will delight enthusiasts of Asian woodland plants. This species is less cold-resistant than classic astilbes (Astilbes chinensis or A. arendsii) but still hardy down to -15°C (5°F). It thrives particularly well in humid and temperate climates, between stones, in a non-scorching exposure. For example, associate it with saxifrages, Corydalis, an elegant capillary, and other small gems that thrive in the same conditions.

Planting and care
Astilbe Saxosa will thrive in moist to wet, well-drained soil, partially shaded, in not too dense shade, or even in the sun if the soil remains consistently moist in summer. A humus-rich and clayey soil is suitable, acidic, neutral or slightly alkaline. This species is sensitive to heat and cannot tolerate any drought. Its foliage can be damaged by scorching sun. It can also be planted by the water's edge in regions with mild winters.

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).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
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 planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
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).
