As a matter of fact, any plants, whether high or low, serve as aground cover in some sense of the word. The tall-growing plants,which are often seen planted in close masses and included in thegroups of tall-growing shrubs, are discussed under the headings of"mass plantings" and also "undergrowth plantations." This dis-cussion does not attempt to treat those groups. It has seemed best, rather than to include in one general list all ofthe plants used for ground cover, to make an effort, at least, to separateinto a number of subheadings the specific uses for which ground-cover plants may be selected. The person familiar with plant adapta-tions knows that there are distinct groups of plants which areadapted to low, moist conditions, as there are distinct groups of plantsadapted to dry and sunny conditions also. Those of us who have hadconsiderable experience in the planting of perennials in different types ofgarden soil, as affected either by the type of soil or the kind of drainage,know that certain plants will thrive in a very moist soil, while otherplants take a great dislike to moist conditions, and will thrive only |
