This is the well-known wild Yarrow; it is, however, the typical form of
a fine variety, called A. m. roseum, having very bright rose-coloured
flowers, which in all other respects resembles the wild form. Both as a
border subject and for cutting purposes, I have found it useful; it
flowers for several months, but the individual blooms fade in four or
six days; these should be regularly removed. The freshly-opened corymbs
are much admired. Soil and mode of propagation, the same as for previous
kinds.
