Foreground Strip

Back of the edging, use slightly taller and less compact spring and early summer flowers, together with a few peren nials and annuals for late summer and early fall. This is the foreground strip. Here is the place for many plants mistak enly used for edging. These should be low but not necessarily compact. In this strip use pinks, campanulas, columbines, trollius, and lungwort. This is also the best place for the low early tulips or hyacinths, if you wish to use them for strong stiff accents. Let this strip be 18 to 24 inches wide.

Iris Strip

Back of the foreground area is an ideal location for iris and the lower-growing daylilies or hemerocallis. This strip can be quite narrow, since the bearded iris does not always hold good foliage through the summer and the daylilies are only for accent, being too bulky if used in quantity. If the space is narrow, the iris can be easily masked by plants grow ing in front or behind. In gardens where only a few iris are desired, this strip may be omitted and the space divided equally between the foreground and the midsummer strip.

The width of these strips is, of course, subject to your own preference and to the length and width of the border. The strips must always be in proportion to each other and to the garden as a whole.

Midsummer Strip

Next comes the midsummer strip or middleground area. Unless something is specially provided to carry on succession, there is likely to be a dearth of bloom after the iris and most of the foreground plants have gone by. In this comparatively narrow strip of 18 to 24 inches, plant biennial Canterbury bells and foxgloves with perennial lupine, Chinese delphin ium, and Phlox Miss Lingard.

This is also a very good place for tulips. Their color, added to that of the spring perennials, creates a larger picture and gives a feeling of greater depth of bloom. As this strip is far enough back to be masked by the growing perennials, the ugly and so-slow-to-mature tulip foliage will not be so annoy ing there. (See list of plants on page 105 ff.)

Late Summer Strip

Behind the narrow midsummer strip comes the late-summer area, the widest division in the border. It may be 3 to 5 feet, depending on the effect planned, the over-all size of the gar den, or whether tall background plants are needed. Here must be accommodated a number of plants important for late sum mer and early fall bloom. Most of these are vigorous growers and need plenty of room. Phlox, the larger hemerocallis, del phinium, hardy garden lilies, veronicas, platycodon, and the taller hardy chrysanthemums, Salvia farinacea, thalictrum, verbascums, and annual zinnias and marigolds belong here.
