So far as we know the plant referred to in the following has not been introduced into our country, but is worth bringing in. The A. iomentosa is somewhat hoary, and makes a very good edging. This one is now common in American gardens: " If I were asked to name the most useful, and, at the same time, the most lovely of the dwarf white edging plants now in use, I should say Achillea umbellata. It is perfectly hardy, and certainly requires less manipulation than the dwarf Cerastium tomentosum. The latter requires renewing every year, whereas the former will be as effective the second and third year as the first. For carpet bedding it is a gem in every way, and only requires to be known to be appreciated. It is easily increased by cuttings taken off in September or October, and dibbled in very thickly under a wall. We have thousands planted under the foot of a west wall, and they give no more trouble than this - after a severe frost in spring, to sprinkle a little sifted leaf mould over the cuttings, and with the hand press into the soil those that have been forced out by the frost.
The few leaves falling from the fruit trees give sufficient covering now until rooted, after which they will take care of themselves."
