Description
Astilbe myriantha (Syn. A. rivularis var. myriantha) is similar to the A. rivularis species, but it produces later, pale pink inflorescences instead of white ones, which are more flexible and branched. Its growth is also more significant, making it a magnificent plant for the moist locations it loves. Its tall floral stems dominate a bunch of finely cut green leaves, giving it a beautiful elegance. A perennial plant that will delight Himalayan flora enthusiasts!
Astilbe myriantha, from the Saxifragaceae family, originates from Southwest China and the Himalayas, specifically Nepal. It is an herbaceous perennial plant with a rhizomatous root system that is adapted to humus-rich and moist soils, and is quite water demanding. Within a few years it forms a beautiful clump of foliage that somewhat resembles a fern. This foliage, which emerges in spring, is composed of a group of leafy stems. The leaves are compound, with deeply toothed large leaflets, of a medium green colour. In moderate climates, flowering begins in July-August. Slender floral stems, reaching a minimum height of 1.50 m (5ft) (up to 2 m (7ft) in optimal conditions), emerge from the foliage. Abundant, this flowering takes the form of long, branched and pyramidal spikes, with a feathery appearance, where numerous tiny flowers cluster together. Their salmon-pink colour becomes lighter at full bloom, then they turn brown as they fade. It is a deciduous plant, with aerial vegetation that dries up and dies in winter, and regrows in spring.
This Astilbe myriantha thrives near a water source that serves as a mirror, giving it a unique charm. This very beautiful plant also enjoys gently shaded beds where the soil remains moist even in summer. It can be associated, for example, with lovely shade companions such as ferns and Giant Hostas. Its pink plumes contrast pleasantly with the large flowers of Hydrangeas. Planted in ribbons, Astilbes highlight shaded paths along with Liriope muscari and saxifrages. Their fern-like foliage lightens that of their opulent neighbors. Also, consider pairing them with rhubarbs. Their feathery blooming complements that of persicarias or bugbanes. Astilbes can tolerate exposure to the sun if it is filtered and the soil remains consistently moist.

Planting and care
Astilbe rivularis var myriantha prefers to be planted in moist and heavy soil, in partial shade. It will tolerate moist soil but not dry, and a sunny exposure if it is filtered. It does not tolerate very chalky soils well and particularly appreciates soils rich in humus. Optionally add compost in spring, or a complete fertiliser rich in potash, to promote abundant flowering. It is a perennial that is not afraid of the cold, being perfectly hardy down to at least -20 °C. Furthermore, it is not sensitive to diseases and has few natural enemies. At the end of flowering, you can cut the faded stems to allow the clump to regenerate.

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.
