Hibiscus, Mixed Colors Three $0.95, D'oz. $3.00,100 $18.00 
HYPERICUM - St. John’s Wort 
Many of the species are small, dwarf shrubs. However, there are quite a 
few that are true perennials. The flowers are yellow and noteworthy for 
the prominent group of stamens in the center. All are lovely garden sub¬ 
jects for borders as well as the rock garden. 
Culture. The dwarf species should be grown on the margin and the 
taller one toward the front of sunny borders. Good, ordinary or sandy 
soil will suit their requirements. Calycinum is suitable for covering banks 
or massing. Plant in early spring, 8 to 10 inches apart. The perennial 
varieties may also be planted in the fall.

Distinct, prostrate, trailing species from the Himalayas. Very large, soft 
yellow flowers, tinged reddish in July and August. Good rock plant. 
Shrubby varieties for low borders and rock gardens. 
IBERIS - Candytuft 
Although these plants are perhaps more generally grown in the rockery, 
they are equally appropriate subjects for the margins of herbaceous 
borders or as edging to garden walks. When in flower in spring and 
covered with a mass of snow-white blossoms, they add considerably to 
the attractions of the garden. They are of shrubby growth, with dark 
green, evergreen foliage. 
Culture. Grow in good, ordinary soil. Plant in fall or spring, 6 inches 
apart. When plants become straggly, trim them directly after flowering. 
♦Little Gem (true form) Three $1.40, Doz. $4.00,100 $25.00

of our best rock or edging plants; perfectly hardy.

Covered with a sheet of white flowers in spring, completely covering its 
rich dark green foliage; a particularly fine plant for the border. Does 
well in light shade and therefore excellent as a ground cover in front of 
shrubs. May be used for edging to parks or walks. Little Gem, however, 
is more formal and upright for these purposes.
