terraces on a large scale, the dwarf iris, evergreen candytuft, tunica, andspeedwell are plants which should be used. It is quite probable, inmany instances on paved areas which to be on a firm foundation havebut a small layer of loam between the stone and the cinders, that theseplants will be frequently winter-killed and require replacing. If it sohappens that these paved areas can be successfully laid, because oflocal climatic conditions, upon a good depth of sandy loam, thenthese plants must seldom be replaced, but rather frequently thinnedout. There are many indigenous mosses which can readily be trans-planted in tufts to fill the crevices between the stones on paved walks,thus presenting the appearance of age during the first years after con-struction. Most of the mosses require a considerable quantity ofwater to make them thrive. There are a few varieties, however,found in open, sunny locations, that will thrive with little moisture.Therefore, before using moss to fill the crevices between flags on pavedareas, the natural habitat of the moss to be used should be known. |
