Description

The Achillea ptarmica 'Boule de Neige' is a wonderful variety of sneezeweed with double flowers, vigorous and highly floriferous throughout the summer. Sprinkled with fluffy white pom-pom flowers, this rounded tuft-shaped perennial appears covered in snowflakes. Unlike many other yarrows, this one prefers moist to even wet, non-limestone soils. Very hardy and charming, it thrives in full sun or partial shade, in flower beds, and near water sources.

The Achillea ptarmica 'Boule de Neige' is a deciduous perennial herbaceous plant belonging to the Aster family with a creeping rhizomatous rootstock. Its above-ground growth emerges in spring, dries up and disappears in autumn. Its ancestor, sometimes called silver buttons, sneezewort, marsh yarrow, sneezeweed or stone-breaker, is a species widespread in northern Europe and Asia. Its natural habitat consists of meadows and wet areas. This 'Snowball' variety has a bushy and carpeting habit. The slightly creeping stems bear slender, lanceolate, dark green leaves. Flowering occurs from July to September. At the end of 60 cm (24in) tall stems, numerous pure white, double flowers with a diameter of 1 cm (1in) appear.

The Achillea ptarmica 'Boule de Neige', which is highly frost-tolerant (-20°C), makes a lovely companion for other perennials that prefer moist to wet soils. For example, you can pair it with ragged robin, astilbes, plume thistle, and meadowsweet (Filipendula). Aphids often attack sneezewort to the point that it is known in organic gardening to prevent or avoid other plants from being invaded by aphids. It is ideal in herb gardens, flower beds, wildflower meadows, or as a cut flower. It pairs well with Caucasian scabious and phlox.

Achillea : planting, growing and care

Read article

Easy to cultivate, <a href="https://en.promessedefleurs.eu/perennials/perennials-by-variety/achillea.html" target="_blank" rel="noopener">Achillea</a> or Yarrow is a wonderful perennial plant that with its summer flowering brings an irresistible natural and wild touch to the garden! Moreover, it is an excellent medicinal plant with multiple properties. It also allows for the creation of stunning bouquets of fresh or dried flowers. A good companion plant to place near the vegetable garden, it attracts pollinators and repels pests! The type species, common yarrow or Achillea millefolium, features delicate white flowers. If it proves too pale for your taste, discover the horticultural varieties, which offer a wide range of colours, often in warm tones! It can take on bright yellow, red, pink, or mauve hues. Common yarrow is very widespread, but whatever the colour, it fits perfectly into naturalistic gardens, wild meadows, sunny rockeries, or borders. It is unmatched in adding a splash of colour and dynamism to flower beds. We love it for its natural and wild character! Yarrow is an excellent perennial to plant in hot and dry conditions. Hardy, it is not very susceptible to pests and diseases, and it is also resistant to heat and drought! It requires no special attention. In fact, it is even advisable to install it near a vegetable garden, as it will repel harmful insects. It is a top choice for dry, poor and sunny soils! It requires little attention and will charm you with its generous summer flowering. It can cover ungracious or difficult-to-cultivate areas, neglected spots where other plants do not thrive. Once established, it spreads easily thanks to its rootstock and self-seeds spontaneously. So if your land is dry and poor, take advantage of it! Rich soils might, on the contrary, make it more fragile.
