This young plant has grown well and will soon bloom, but there is a slight drawback: it cannot tolerate the sun during the hottest hours of the day, between 11 am and 2 pm (even though it is in the shade before 11 am and after 2 pm). Its leaves have burned and turned yellow, so we will either need to protect it or move it.

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.
