Hardy Perennial and Rock-Garden Plants 
Experience with this class of plants has shown that, in most instances, vigorous, pot-grown 
plants of proper size will give as quick and as good returns as the best field-clumps. Our pot-grown 
plants were lifted from the field and potted up during the fall. Such stock may be planted, even 
late in the spring, with practically no risk of loss. 
Varieties marked with an asterisk (*) are suitable for rock-gardens 
ACHILLEA. Milfoil; Yarrow. 
The following varieties require a sunny 
position. Cut the shoots back directly after 
flowering. Divide and replant every third year.

Pure white, double flowers borne in graceful 
sprays all summer. Fine for cutting. 1 ft. 
Ptarmica, Perry’s White. Large, pure white 
flowers with broad, overlapping petals. 1 to

mer. Excellent for rockeries. 6 to 8 in. 
ALYSSUM. Rock Madwort; Basket of Gold. 
♦Saxatile compactum. Splendid plant for the

flowers in dense, compact heads in early 
spring. Full sun. 1 ft. 
AQUILEGIA. Columbine. 
Thrive in light, loamy soil and partial shade. 
Dobbie’s Imperial Hybrids. New, long-

range of colors and sturdiness, and will charm 
you by their beauty. 
ARMERIA. Thrift; Sea-Pink. 
♦Formosa Hybrids. Dwarf-growing perennials 
with tufts of bright evergreen foliage from 
which innumerable deep pink flowers appear 
in dense heads from May until July. Useful 
in the rockery and as edgings to borders and 
beds. Sunny position in dry sandy soil. 1 ^ ft. 
AUBRIETIA. Purple Rock-Cress. 
♦Deltoidea. Attractive for the rock-garden or 
as edgings and for carpeting bulb-beds. They 
form masses of silvery green foliage and sheets 
of lavender-blue flowers during spring and 
early summer. Require rich, well-drained soil 
as on heavy or damp soil they may freeze out. 
BAPTISIA. False Indigo. 
Australis. Attractive, dark blue, pea-shaped 
flowers in long, curving racemes, somewhat 
similar to lupines but more hardy in every 
way. Suitable for the hardy border or wild 
garden, and not particular as to soil-require¬ 
ments. Blooms in June. About 2 ft. 
BELLIS perennis. English Daisy. 
These are favorites for edgings, in colonies, in 
borders, or carpeting beds of bulbs. They will not 
thrive in dry, hot positions, but require a fairly 
fertile, moist soil. A bed or border of pansies 
with English Daisies is charming.
