PERENNIALS FOR DIFFERENT PURPOSES : Page 606
For planting on the land at the water's side, a still larger list of plantsis available. These include many of our common herbaceous gardenperennials, such as sneeze-weed, Japanese iris, and lemon lily, as well asnative herbs, such as gentians, cow parsnips, and some of our nativeorchids. With these perennials should be combined, if possible, someof the moisture-loving native shrubs. For this purpose nothing is bet-ter than the swamp honeysuckle, button bush, red chokeberry, rhodora,leather leaf, and wild rosemary, not to mention the more commonlyknown dogwoods or cornels.
If no special place is assigned to perennials, room may always befound for some in the shrub border. Here there should be reluctanceto place any sorts that require considerable culture or the full develop-ment of which might be desired, particularly if they be sorts that areprized. One would be loath to subject a valuable variety of the peony,for example, to a life-long competition with vigorous shrubs which,in addition to sending out more rapid-growing roots, would have theadvantage of overtopping it. But there are certain types of perennialsthat can, in every way, be appropriately used to fill bare spaces amongshrubs that do not yet cover all the space, or at the front edge of theborder. Here at the edge, if the shrubs do not droop too low or arenot too vigorous in their habit of growth, may be found a place for a
