Thalictrum Aquilegifolium 
STOKESIA - Cornflower Aster; Stokes’ Aster 
A very handsome perennial, with China-Aster-like flowers, that appear 
late in the season, about September. It prefers a warm, sheltered loca- 
tion. Should certainly be grown in all gardens since its flowers are most 
beautiful in form and color. 
Culture. Grow in a sunny, well-drained border in sandy loam, 6 inches 
apart. Plant in March or early autumn. 
Blue Moon Three $1.85, Doz. $5.50, 100 $35.00 
The immense light blue disc-like flowers are 5 to 6 inches in diameter, 
growing on stiff 12- to 18-inch stems. In the foreground of the bor- 
der they make a picture not easily duplicated. Stokesia, Blue Moon, 
is GQ vigorous-growing and free-flowering variety of exceptional merit 
and distinction. It is perfectly hardy and has no insects bothering it. 
It is of easy culture and flowers throughout the summer and autumn 
until stopped by hard frosts. A most worth-while addition to the 
hardy plant garden.

TEUCRIUM - Germander 
Shrublike plants of moderate growth. Chamaedrys has shrublike, shiny, 
dark leaves. 
Culture. A well-drained, good garden soil is all that is required to grow 
them to perfection. Plant in fall or early spring, 6 inches apart in full 
sun, in rock garden or border. Chamaedrys may also be used as an 
edging to flower beds or garden plants in the small formal garden. 
**Chamaedrys Three $1.50, Doz. $4.75, 100 $25.00 
Glossy green foliage resembling dwarf boxwood, may be used in place 
of boxwood where the latter is not hardy; can be clipped to suit any 
height up to 12 inches. 
THALICTRUM - Meadow-Rue 
Hardy perennials, with elegant, finely divided, Columbine or Maiden- 
hair-like foliage, which is most useful for cutting for mixing with cut 
flowers. Are borne in feathery clusters or panicles, and they add con- 
siderably to the beauty of the plants. They are of easy cultivation in 
sun or shade. 
Culture. They will thrive in any good, ordinary, well-drained soil. May 
be grown in sunny or partially shaded borders, are most effective when 
grown as single specimens in the front of shrubbery borders, or in the 
wild garden. Plant in autumn or spring, 8 to 12 inches apart. 
Aquilegifolium Three $1.50, Doz. $4.75, 100 $25.00

Poppy Wm. Perry.

Similar in habit to the Aquilegifolium; blue-gray leaves rather finely 
cut, with heads of Chinese yellow, fragrant flowers. 3 to 4 feet. July 
THERMOPSIS 
Only one species is worthy of mention here. This has three-foliate 
leaves, and yellow, lupine-like flowers borne in long, terminal racemes. 
It is of graceful growth and specially suitable for the sunny border.

autumn or spring, 8 inches apart. 
Caroliniana Three $1.50, Doz. $4.75, 100 $25.00

high. In June and July, yellow, pealike flowers are produced in racemes, 
6 to 12 inches long. The general appearance is that of a yellow lupine. 
THYMUS - Thyme 
Dwarf-growing, almost prostrate creeping perennials with fragrant foli- 
age, suitable for growing on the margins of dry, sunny banks, slopes or 
rock gardens. 
Culture. These will thrive in ordinary soil in well-drained, dry borders 
or on sunny slopes and rockeries. They soon spread and form neat 
patches of foliage, studded in summer with rosy purple or crimson 
flowers. Plant in autumn or spring, 6 inches apart. All flower in June
