HARDY PERENNIALS 
Varieties of Perennials marked thus * are ideal for rock garden planting. See also Evergreen, 
Shrub and Bulb Sections for suitable rock garden varieties. 
Achillea (The Pearl). Is one of the most beautiful and 
useful pure white flowers. Grows to a height of one 
and two feet. Blossoms from June or July till Fall. 
It is of a low rather spreading habit. The flowers are 
on erect, sturdy stalks and produced in large sprays 
or panicles; especially fine for cutting; popular for 
cemetery flowers. The plant was named for Achilles, 
the Greek hero, who is said to have discovered its 
medicinal properties. A fine border plant. 
Adam’s Needle. For description sec Yucca. 
*Alyssum Saxatile (Goldentuft). A fine border or 
rockery plant, not over 12 inches high, which bears 
numerous clusters of bright yellow flowers in May. 
Similar in shape to the well known Sweet Alyssum. 
Anchusa Italica (Alkanet). The Anchusa is a new 
form of the old Italian Alkanet, and takes a supreme 
rank among the perennials. It forms a dense, rounded 
bush four feet tall, which in late May or June is cov¬ 
ered with masses of rich, dark gentian or cobalt blue 
flowers an inch wide, which continue to bloom all 
summer if not allowed to go to seed by cutting off the 
flowers as they fade. Has rough leaves and stems, 
branches freely, and is unusually taU for a perennial. 
Is easy of cultivation but prefers sunlight. Is strik¬ 
ingly handsome in perennial borders, where its height 
serves to accentuate the landscape; is especially 
effective when seen in large masses at a distance, be¬ 
cause of its briUiancy. Honey bees are very fond of 
its flowers. A very flue perennial to plant for its cool, 
refreshing appearance when seen in perspective. Fine 
for cut flowers also, for the house, or for decoration 
for church and cemetery bouquets. 
^Anemone Japonica or Windflower —So called from 
Anemos—Wind, because it grows naturally in ele¬ 
vated places, exposed to the wind. We grow the 
Japanese because of the late blossoming qualities, 
which make it more useful. Grows two to three feet 
in height. The flower stems are tall and stately. 
Flowers are about two inches across—waxlike, very 
dainty and very superior for cutting, especially for 
church and cemetery decoration when other flowers 
are scarce. A good plant in any location, but has 
several special uses because it will thrive in the rock 
garden or in thin rocky soil, also in the half shady cor¬ 
ner, and because it blossoms from late August to 
middle November, when other flowers are scarce. The 
flowers are large, open, double or semi-double, and a 
' group of these superb blossoms waving gently to the 
wind is a sight that gladdens the eye in Autumn. 
We grow the three following varieties: 
*Anemone Hupehensis. Produces an abundance of 
beautiful pink flowers starting in August and continu¬ 
ing until frost. Dwarf variety growing 12 to 18 inches 
high. Grows vigorously in ordinary garden soil in sun 
or light shade. Excellent for rock gardens. 
Anemone Queen Charlotte. Semi-double flowers 
of delicate rosy, daybreak pink. 
Anemone Whirlwind. Semi-double purewhite flowers. 
Aquilegia or Columbine—Giant Flowering Hy¬ 
brids. This greatly improved form of the Columbine 
produces flowers 3 to 4 inches across and with very 
long spurs, borne on graceful stems well above the 
foliage. The blooming season has been much length¬ 
ened and many beautiful colors and shades added. 
Highly recommended for rock gardens. It does well 
in sun or shade and is altogether a very valuable 
little plant. It grows two to three feet tall and has 
attractive foliage. Good for any location. Blooms 
May to July. 
*Arabis Alpina (Rock Cress). Dwarf, early blooming 
plants, in their blooming period covered with dense 
masses of pure white flowers. Splendid for border, 
rockery or for covering steep banks. April and May. 
Artemisia Silver King (Sage Brush). A shrubby, 
sagelike plant, ideal for border planting. Its striking 
fine cut, bright frosted silver leaves make it an ideal 
contrast plant. Grows 3 feet tall. Its long, gorgeous 
sprays are used extensively for setting off bouquets 
and floral pieces. Also is beautiful for Winter 
Bouquets. 
Aster Cornflower (Stokes Aster) (Also called Stok- 
esia). We favor the Stokesia cyanea, the light blue or 
lavender-blue variety. A grand, large-flowered hardy 
perennial, eighteen to twenty-four inches tall, cov¬ 
ered with beautiful flowers, often four and five inches 
across, and blooming continually from July to Octo- 
An attractive though small Rock Garden. Sedum
