Astilbe ‘Purpurlanze’, commonly referred to as Lilac Astilbe or Purple Lance Astilbe, is a striking herbaceous perennial known for its vibrant lilac-purple flower plumes and finely textured foliage. This robust plant thrives in moist, shaded areas, bringing bold colour and texture to borders, woodland gardens, and water features.

Description

Astilbe ‘Purpurlanze’ grows to a height of 60–80 cm (24–32 inches) with a spread of 45–60 cm (18–24 inches). Its dark green, fern-like leaves form a dense, attractive mound that provides a beautiful backdrop for its vivid flowers.

In mid to late summer (July to August), tall stems carry dense, upright plumes of rich lilac-purple flowers. These long-lasting blooms create vertical interest and add a vibrant splash of colour to shaded or partially shaded areas.

Growing Conditions

Astilbe ‘Purpurlanze’ thrives in partial shade to full shade and prefers consistently moist, well-drained soil. It performs best in rich, humus-rich soils with a slightly acidic to neutral pH. While it can tolerate full sun in cooler climates, too much direct sunlight may cause leaf scorch.

This variety is hardy in the UK, tolerating frost and returning reliably each year, making it a dependable choice for temperate gardens.

Propagation and Care

Astilbe ‘Purpurlanze’ is propagated by division:

• Division: Divide mature clumps in spring or autumn, ensuring each division includes healthy roots and buds. Replant divisions in prepared soil at the same depth.
• Spacing: Allow 45–60 cm (18–24 inches) between plants to accommodate their mature size and promote airflow.

Routine care includes:

• Watering regularly to maintain consistent soil moisture, particularly during dry spells.
• Mulching annually to conserve moisture, suppress weeds, and enrich the soil.
• Cutting back spent flower stems and foliage in autumn to tidy up and prepare the plant for winter dormancy.

Uses
