Graduated planting from low 
to high in the perennial bor¬ 
der affords each group the 
desirable space for display of 
blooms 
Rock Cress (Arabis albida ) 
Small loose clusters of fragrant 
white flowers which grow 6" to 
8" high. The flower is a little 
coarse, but the foliage, which is 
persistent, and nearly evergreen, 
forms dense tufts and has a 
grayish appearance. Blooms in 
April and early May. Propagate 
by seed, cuttings and by division. 
Thrift (Armeria maritima var. 
splcndens) 
This little pink flower, which 
blooms in dense heads on naked 
stalks from 2" to 12" high, 
springs from a rosette of narrow 
evergreen leaves which grow 
close to the ground and have a 
very neat appearance. Blooms 
in late May and early June. 
English Daisy (Beilis perennis) 
An old favorite with its abun¬ 
dant crop of stiff, double, daisy¬ 
like flowers tipped with pink. 
Has good foliage which is per¬ 
sistent and clusters around the 
base of the plant. Blooms all 
summer. In winter it should 
have a slight protection. Propa¬ 
gate by seed sown in the spring 
Rock cress, Arabis albida, 
blooms in April and May, 
forming dense tufts of fra¬ 
grant white flowers with 
grayish foliage 
or by root division in the fall. 
Carpathian Harebell (Campanula 
carpatica) 
This is the only one of the 
charming bluebells which can be 
used for effective edgings. It 
forms dense masses of delicate 
foliage from 6" to 12" high, and 
is covered with solitary purplish- 
blue flowers in July. There is 
a white variety which is also ef¬ 
fective. Root division is the 
surest and most easy method of 
propagating, but seeds may be 
sown. 
Snow-in-Summer (Cerastium fo¬ 
ment o sum) 
This is a very popular edging 
plant. The wonderful silver- 
gray foliage is effective even in 
winter, when there is little in the 
garden to charm. The single 
flowers are small, but in masses 
it gives a pleasing shoal of white 
which serves as a good foil for 
the other flowers in the border. 
Seeds or division are the means 
of propagating. It spreads 
rapidly and one is usually able
