Persicaria amplexicaulis 'Blackfield'

Persicaria amplexicaulis ‘Blackfield’ – Mountain Fleece

Persicaria amplexicaulis ‘Blackfield’ is a strong, long-flowering perennial with striking dark wine-red to almost black-red flower spikes. The intensely coloured flowers rise elegantly above the fresh green foliage and provide a beautiful splash of colour from summer well into autumn.

‘Blackfield’ forms a compact, bushy clump of around 70 cm high. During flowering, the flower spikes rise clearly above the foliage, bringing the plant to approximately 100 cm in height. This creates an airy vertical accent without making the plant look heavy or bulky.

🌸 Striking dark flowers and a long flowering period

The almost black-red flower spikes are the main attraction of this Persicaria. From summer onwards, new flowers continue to appear, ensuring a long flowering period and keeping the plant attractive well into late summer and autumn.

The flower spikes move gently in the breeze, giving the plant a natural appearance. ‘Blackfield’ is therefore an excellent choice for both colourful borders and more naturalistic planting schemes.

🐝 Valuable for pollinating insects

The numerous small flowers are attractive to bees, bumblebees and other pollinating insects. Thanks to its long flowering period, this perennial provides a valuable food source for insects over a large part of the growing season.

Persicaria amplexicaulis ‘Blackfield’ is therefore an excellent choice for a biodiverse garden.

🌿 Strong and versatile

This mountain fleece is a reliable perennial that grows back from the base each year. It is particularly suitable for borders, larger planting beds, prairie gardens and naturalistic planting.

The dark flower colour combines beautifully with ornamental grasses and perennials in soft, light or contrasting colours. It pairs particularly well with Echinacea, Rudbeckia, Anemone, Salvia, Verbena and various ornamental grasses.

☀️ From full sun to partial shade

Persicaria amplexicaulis ‘Blackfield’ grows well in full sun to partial shade. Flowering is generally most abundant in a sunny position, but this strong perennial also performs well in somewhat shadier conditions.

It prefers a humus-rich, fertile and sufficiently moisture-retentive soil. Even moisture during the growing season promotes strong growth and abundant flowering.

✂️ Easy to maintain

‘Blackfield’ requires little maintenance. After flowering, the spent flower spikes can be left standing to provide a natural winter effect. Cut the plant back in late autumn or early spring.

The plant will emerge again from the base in spring.
