Description
Thalictrum 'Splendide Album', with its pure white flowers, completes the delightful collection of giant meadow rues. It is a variety of beautiful stature, with finely cut and chiselled blue-green foliage, and a generous summer flowering, which crowns its vegetation with a cloud of small pure white flowers. An elegant but hardy and robust perennial. Wonderful in partially shaded or sunny beds, in moist soil.
Thalictrum delavayi, also known as Thalictrum dipterocarpum and sometimes called Delavay's meadow rue, is a rhizomatous perennial plant native to the Himalayan region of Asia, from eastern Tibet to western China. It belongs to the Ranunculaceae family. It is found in the wild at high altitudes, in forests, scrubland, and grassy slopes. 'Splendide Album', also known as 'Splendide White', is a white-flowered clone of the beautiful cultivar 'Splendid'. It is an herbaceous perennial, with an upright and erect habit, forming a bushy clump, from which flexible stems rise, reaching a height of about 1.5m (5ft) (sometimes more), with a width of 30 to 40cm (12 to 16in). Its finely cut and very light deciduous foliage resembles that of a columbine. It is composed of pinnate or ternate leaves, 15 to 35cm (6 to 14in) long, with entire or trilobed leaflets. They are glaucous green on top, with a bluish hint below. In July-August, large, loose, well-branched, terminal and axillary panicles appear, composed of small star-shaped flowers with four pure white sepals, enhanced by prominent yellowish-green stamens. They do not like competition from nearby roots so respect a planting distance of 40cm (16in) around its base. Meadow rue is quite slow to establish, but will become increasingly beautiful over time.
Thalictrum delavayi 'Splendide Album' provides the same ornamental function as baby's breath, but it prefers the cool and shaded areas of the garden. With its size, its delicate and elegant foliage, and its airy appearance, it will be perfect for adding height and lightness to beds. Despite its size, it can be planted at the front of flower beds. It will be particularly effective in contrast with less delicate perennials (rodgersia, hosta), as well as on the edge of shrub beds. It will naturally find its place alongside hostas, hydrangeas, shrub or climbing roses, fuchsias, Japanese anemones, aconites, astilbes, campanulas, alder buckthorn, snowberries, ferns, hellebores, foxgloves, grasses, perennial geraniums, elderberry, and Sacred Bamboo.

Planting and care
Thalictrum delavayi 'Splendide Album' is a hardy and low-maintenance perennial. It simply needs to be planted in partial shade or even full shade, in moist to damp soil that is rich in organic matter and well-drained, without too much limestone. It is possible to establish it in the sun, as long as the soil remains moist and there is ambient humidity surrounding the plant. Planting can be done in spring or autumn. Ideally, plant it at the base of a north or east-facing wall. It is advisable to add compost to the soil every year to improve drainage in winter and facilitate root development. Regular watering is also necessary during dry and hot periods. Regularly deadhead the flowers to prolong the flowering period. The plant loses its leaves in autumn and completely disappears in winter, only reappearing quite late in spring. Therefore, do not cut the plant back in autumn so you can find it again in spring! As it can grow quite large, staking may be necessary, especially if it is used as a standalone plant or in a windy location. To avoid this inconvenience, it is advisable to plant it among other plants and bushes that it can lean on for support. Divide the clumps in March-April by cutting the clump into several pieces with a spade. However, the divisions take a long time to establish. Although highly resistant to diseases, it may be susceptible to powdery mildew during dry spells, and slug attacks at the start of the growing season.

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.
