Description
Astilbe x arendsii 'Spinell' is one of the largest red hybrids. Its early flowering in long crimson panicles will brighten up the surroundings of water features, moist areas of the garden, or a large container on the terrace. Its feathery plume-like panicles remain very attractive in dried flower arrangements and the foliage takes on beautiful hues in autumn. Suitable for moist soils.
'Spinell' Astilbe is a perennial plant with a dense crown, which forms an upright clump in spring. It is one of the many hybrids created in Germany by Georg Arends, obtained from four species native to the Far East (A. astilboides, A. davidii, A. japonica, A. thunbergii). The plant will reach 90 cm (35in) in height when in flower and will spread over 50 to 70 cm (20 to 28in).
This large astilbe forms a bushy clump and is a long-lived plant, with deciduous compound foliage and dentate dark green leaflets. Flowering occurs from late spring to early summer, in the form of large feathery panicles, 25 cm (10in) long, composed of tiny, soft, bright carmine-red flowers.
'Spinell' Astilbe can easily be grown in a container, as a bog plant, in a flower bed, as a border plant, and used as cut or dried flowers. It can also be grown in a woodland setting, in a hedge, and of course in a flowerbed. Combine with Hostas, Ferns (Athyrium filix-femina), Arums, Beardtongue, and Queen of the Meadows (Schizostylis coccinea 'Major') and Filipendula rubra ‘Venusta'. These plants can be forced in a greenhouse to obtain early flowering.
Arends hybrids have a lower risk of causing allergies, compared with other Astilbes. In Asia, dried leaves are sometimes used as a substitute for tea, and the young stems are cooked and eaten.

Planting and care
Plant Astilbe x ardensii Spinell in moist to damp, rich, neutral to acidic soil. This hybrid cannot tolerate a lack of water. The plant adapts well to clay soils if they are healthy and fertile. Note that Astilbes do not tolerate being flooded in winter. Plant Astilbe Spinell in partial shade or in a sunny, but not scorching, location: in nature, these plants grow in moist understory. Daily watering will be necessary in hot summers. Prune faded flowers to promote better leaf development. The flower stalks can also be left in place to decorate the garden during winter, simply remove them the following spring. Avoid digging near these plants as the rhizomes develop near the surface. These plants are disease-resistant and rarely attacked by insects.

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.
