Description
Veronicastrum sibiricum, or Siberian Speedwell, is a tall, spectacular perennial with proud upright mauve flower spikes during the summer. The remarkable foliage is arranged in whorls around the stems. The plant eventually forms a dense clump, which will bring lightness and height to partial shade borders, in moist to wet soil.
The Siberian Speedwell is a plant in the Plantaginaceae family (it was previously classified among the Scrophulariaceae). It also grows in China, Mongolia, Korea, and Japan, where it can be found in ditches along roads, on grassy slopes, or woodland edges. This impressive plant produces tall upright stems, adorned with lanceolate medium green leaves, arranged in successive rings, or whorls, around the stems. Between July and September, each stem produces a mauve-pink "candle" (occasionally white in its natural habitat) at its tip, an elongated, 20 cm (8in) spike of many small nectar-rich flowers with prominent stamens, giving it a very distinctive airy appearance. Overall, the species closely resembles Veronicastrum virginicum, its American cousin, but can be distinguished by slightly wider leaves and a little branched or unbranched inflorescence which accentuates its airy character. In autumn, the foliage turns a beautiful yellow before drying out. In good conditions, the plant will reach between 1.20 and 1.50 metres (4 and 5 feet) high, eventually forming a clump with a diameter of 50 to 80 cm (20 to 32in) after a few years.
Very hardy Veronicastrum sibiricum can withstand temperatures as low as -20°C. It prefers well-drained, rich, and moist, even wet soil. If the soil is too dry in summer, the plant fades and flowering can be compromised. The steep bank of a pond or a sunny border are excellent places to plant speedwell, which still needs several hours of (non-scorching) sun per day. The clump slowly expands through its non-invasive small rhizomes, so give it some space.
Pair it with other lush waterside perennials, such as Ligularia stenocephala, another tall plant, or its low-growing cousin Ligularia dentata 'Desdemona', as well as marsh spurge for a contrast of foliage and colour. You can also play contrast using tall fountain grasses like Molinia arundinacea 'Windsaule'.

Planting and care
Plant Veronicastrum sibiricum in close to neutral, moist, humus-bearing, deep and fertile soil, in spring or autumn. It prefers dappled sun or partial shade, but can tolerate more sun if its base is always moist. Water regularly in dry and hot summers. Avoid moving once established.

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.
