Eryngium Amethystinum (See page 38) 
DORONICUM - Leopardbane 
Very showy yellow-flowered perennial. Their yellow, daisy-like flowers 
are invaluable for cutting. As they flower chiefly in spring, they are 
indispensable in the border at that period of the year. They have bright 
green, heart-shaped leaves which disappear during July and August 
when the plant is dormant. 
Culture. Thrive well in heavy soils and succeed in sunny or partially 
shaded borders. Best grown in groups of six or more. Plant in autumn 
or early spring, 6 to 8 inches apart. Lift, divide and replant every third 
year; remove the flower heads directly after they fade, then a second 
crop of flowers will follow. Water freely in dry weather. Lovely with 
pale lavender Tulips. 
Caucasicum Three $1.40, Doz. $4.00, 100 $25.00 
Large, bright yellow flowers on 2-foot stems; one of the most effective 
early spring-flowering perennials. Effective in a hardy border in com- 
bination with Tulips. It is a splendid flower for cutting, as it carries well 
and stands a long time in water. 
Clusi Three $1.50, Doz. $4.50, 100 $30.00 
Grows about 12 to 15 inches tall with large yellow daisy-like flowers. 
Might be called a dwarf Caucasicum. 
Pardalianche (Bunch of Gold) Three $1.50, Doz. $4.50, 100 $30.00 
Of upright growth, 214 to 3 feet. Stems much branched, covered with 
small yellow daisy-like flowers. Excellent for cutting and planting with 
Darwin Tulips. Does well in moist soil or light shade. 
DRABA - Whitlow Grass 
One of the important spring-flowering plants for the rockery. Very dwarf 
and compact with numerous small flowers in early spring. 
Culture. A sandy, rocky, open soil and a sunny, well-drained position 
suits them best. Do not cover plants during winter with any material 
that might rot the evergreen foliage. 
*** Fl adnizensis Three $1.75, Doz. $5.00, 100 $35.00 
(Androsacea.) A very hardy species from the Arctic regions. Produces 
a profusion of white flowers from March to May. Fine for rock garden. 
DRACOCEPHALUM - Blue Dragonhead 
Salvia-like perennials. They have palmate leaves, and bear their flow- 
ers in whorls on terminal spikes. Interesting plants for the border or 
rock garden. 
Culture. Grow in ordinary, good soil and in a cool, partially shaded po- 
sition. Best grown in masses of three or more. Plant in fall or early 
spring, 6 to 8 inches apart. 
*Ruyschianum japonicum Three $1.40, Doz. $4.00, 100 $25.00 
A lovely, almost evergreen, hardy border plant, easily grown and good 
looking in front of the border. Resembles a small Snapdragon when in 
bloom. The flowers are blue, grow 2 feet and are at their best in July 
and August. Good for cutting. 
ECHINOPS - Globe Thistle 
Handsome perennials with pinnate or spiny foliage, woolly beneath, and 
globular, thistle-like flowers. A well-grown plant has a pleasing effect 
in the border. 
Culture. Ordinary soil in sun or light shade in border or wild garden. 
Plant in autumn or spring 10 to 12 inches apart. 
Ritro Three $1.10, Doz. $3.30, 100 $20.00

metallic blue flowers during July and August, which can be dried and 
remain attractive for a long time. 2 to 3 feet high. 
EDELWEISS (See Leontopodium). 
EDRAIANTHUS - Wahlenbergia 
Plants allied to the Campanula, and belonging to the same order. They 
are mostly suitable for rockery culture. 
Culture. They will succeed in good, ordinary, well-drained soil, and may 
be grown as an edging or in masses on the margin of a sunny border, 
or rock garden. Plant in spring or early fall, 6 to 8 inches apart. 
*Dalmaticus Three $1.50, Doz. $4.50, 100 $30.00

Doronicum Caucasicum 
EPIGAEA .- Trailing Arbutus 
A somewhat shrubby plant of creeping habit, capital for the shady rock 
garden or open woods. 
Culture. Requires a well-drained, porous soil and a shady but not too 
dry position. Shade the evergreen foliage slightly during winter to pre- 
vent burning. Plant fall or spring, 8 to 10 inches apart. Do not disturb 
when once planted. They are very difficult to establish in new locations. 
Repens Three $1.40, Doz. $4.00, 100 $25.00 
(Mayflower.) Likes acid soil, therefore plant in some place where lime 
will not hurt it. Very difficult to transplant. Sent only at your risk. 
EPIMEDIUM - Barrenwort 
Dwarf perennials with handsomely marked and leathery leaves which 
assume a bronzy tint in autumn. Dainty little plants for colonizing on 
the margins of partially shaded borders and rock gardens. Foliage is 
classic in design and most useful for cutting. 
Culture. Grow in peat and loam in partial shade. Plant in colonies of 
three or more in fall or spring, 6 inches apart. Do not remove old leaves, 
as they help to protect the plants in winter. 
*Macranthum Three $2.00, Doz. $6.00, 100 $40.00 
A dwarf-growing plant suitable for a shady position in the rock garden, 
edge of border or for mass planting under trees where grass will not 
grow. The leathery, bronzy green foliage and panicles of small, cream- 
white flowers in May make it one of the most attractive small plants.
