Description
The hybrid Anemone Frilly Knickers is a medium-sized, floriferous and robust variety with very pretty semi-double flowers that are slightly ruffled. Full of charm, its delicate flowers, tousled, pure white, are infused with a soft lilac. The reverse of the petals is tinged with dark violet. It blooms from July to September, producing beautiful violet buds and numerous flowers, on medium green foliage. A simple beauty that complements other summer and autumn blooms. This perennial thrives in partial shade or possibly in the sun, in moist and rich soil.
The Frilly Knickers Anemone belongs to the Ranunculaceae family. This hybrid, obtained in 2020 by Hardy's, was immediately recognized for its robustness and beauty. Like other hybrids obtained from Japanese anemones, it is a perennial plant with fibrous 'tubers' that form large, vigorous, and rounded clumps. The foliage is deciduous to semi-evergreen in winter depending on the climate. Its leaves are deeply divided, strongly veined on the underside, and hairy. In this variety, the foliage is medium green, and the plant reaches 60 cm (24in) in height when in bloom, with a width of about 45 cm. The abundant flowers appear from early July to September, or even October, and the plants keep flowering as long as the soil does not dry out too much. The flowers are carried by sturdy, well-branched stems. They first appear as delightful oval and fluffy buds, violet in colour, then open up into semi-double cups, with a crumpled appearance, in this harmony of white, mauve, and deep violet. The golden yellow centre is densely filled with stamens. Anemones can live for years in the same spot, as long as the soil is rich.
The Frilly Knickers anemone brings flower beds alive from summer to autumn, in the company, for example, of the Fuchsia magellanica var molinae, the Rabdosia longituba, or asters such as Aster ageratoides 'Stardust', Aster sedifolium, or the Aster novae-angliae and their numerous varieties. It can also be paired with fine-leaved grasses for a contrasting effect, for example, with Carex morowii 'Ice Dance'. It proves to be excellent as a cut flower for your beautiful autumn bouquets.

Planting and care
The Japanese anemone Frilly Knickers grows in partial shade, in a moist, humus-rich, loose soil, without too much limestone. Plant it in a sheltered spot, away from strong winds, in spring or autumn, spacing them 30 cm (12in) apart, in a moist to wet, but well-drained soil. Once the young plants are established, they should not be disturbed. The flowering becomes more and more abundant as the years go by. In late autumn, cut the flower stalks to the ground. Every 2 or 3 years, add well-decomposed compost to their base to enrich the soil, as they are quite hungry.

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.
