The plant is desirable for the background of the perennial 
border. 
Hardy Chrysanthemums.—In recent years the variety of 
chrysanthemums that are available for outdoor planting have 
become very numerous, both pompon and single sorts being 
available. As garden subjects, they are desirable because of 
their late blooming period and thet ability to withstand 
early frosts. The varieties growing about St. Louis are 
mostly old types and should be replaced with newer and more 
attractive sorts. C. maximwm and some of its varieties, such 
as the “Shasta Daisy,” for instance, bloom from July until 
late fall. No garden should be without some of these plants. 
Coreopsis.—C. lanceolata grandiflora, commonly known as 
the tickseed, is a valuable plant for the perennial border: 
The masses of yellow flowers are produced in June, and if 
the plant is cut back after flowering, another crop may 
bloom later in the season. A few seeds sown in the border 
will soon show how easy to grow and how hardy the coreopsis 
is. The best effects are obtained, however, by planting it in 
small groups about the garden. The flowers make beautiful 
cut specimens. 
Delphinium or Larkspur.—Most gardeners about St. Louis 
seem to find larkspurs rather hard plants to handle, but suc- 
cess is largely a matter of getting them established. Like 
the aquilegias, however, they are among the plants that do 
not take kindly to our warm summers, and their culture, 
even though highly desirable, will not be successful without 
very great care. . formosum and its varieties seem to do 
better than D. chinense. 
Dinathus.—These plants, ordinarily known as Sweet- 
Williams or hardy pinks, are an important addition to the 
list of perennials. The flowers are produced in June and 
may be obtained in a variety of colors. Although the flower- 
ing period is short, the plants retain their dark green foliage 
and are always attractive as an edging for the perennial 
border. 
Aen ir. commonly called foxglove, is a de- 
sirable garden subject on account of the vertical lines of the 
flower. The plant itself is low-growing, and care must be 
taken not to crowd it with er material. This is an- 
other perennial that is better grown in partial shade, since 
it is easily affected when exposed to the hot sun immediately 
after a rain. It blooms during July and August and attains 
a height of 3 feet. The flowers are yellow, white, pink, and 
purple, the gloxinia-flowered varieties being the most. at- 
tractive. :
