Achillea ptarmica (The Pearl Group) 'The Pearl' (clonal) (d)

About this cultivar:

Achillea ptarmica (The Pearl Group) 'The Pearl' (clonal) (d) was apparently first intoduced in the late 19th C. in France by Victor Lemoine (1823-1911)- but I can't find much evidence for this! It is a seed raised cultivar that has become so variable a cultivar-group has been named (The Pearl Group) and selections made therein - such as 'Boule de Neige' (Snowball!). However it had to wait over 100 years before it got the RHS Award of Garden Merit in 1999. A favourite of the Edwardian garden guru Gertrude Jekyll, you will get pure white, double, flowers growing in large clusters for a long period of time. It also make a great dried flower or long lasting cut flower. Warning - may self seed a bit! (It doesn't with us but does with others I'm told).

The species name ptarmica comes from the Greek word ptairo meaning “causes sneezing”. Thus historically this species was used as a sneezing remedy.

About this genus:

Achillea, commonly called common yarrow, is a rhizomatous, spreading, upright to mat-forming perennial. Achillea is in reference to Achilles, hero of the Trojan Wars in Greek mythology, who used the plant medicinally to stop bleeding and to heal the wounds of his soldiers.

Often garden Achillea are members of the millefolium species. The specific epithet of millefolium means thousand-leaved in reference to the foliage being more intense than other Achillea. Achillea has a plethora of additional common names, including milfoil, thousandleaf, soldier’s woundwort, bloodwort, nose bleed, devil’s nettle, sanguinary, old-man’s-pepper and stenchgrass.

Yarrow ale was a popular choice for weddings because of its tendency to increase energy, act as an aphrodisiac and generally “make the guests crazy.” At Ballyrobert we use it solely for gardening purposes..... honestly.

There are many cultivars of Achillea in a variety of colours. It prefers to be grown in most soils that are reasonably well drained. Achillea is another versatile plant in the garden at Ballyrobert;  it looks great with all sorts of grasses and prairie style plants but the fern-like foliage and cow-parsley type flower heads also help it blend with some woodland or cottage style plants. When it dies back for the year Achillea dries out fully and gives great structure to the garden - it is often used for dry flowers and flower arranging.
