CYPRIPEDIUM—continued 
*Calceolus pubescens—C. parviflorum and C. pubescens, the 
small and large forms of the Yellow Ladyslippers, are no 
longer considered botanically distinct. They are also re- 
garded as a variety of the European C. Calceolus and we are 
so listing them. However, we are keeping the two forms 
separate for garden purposes. These are mid- and late- 
Spring blooming Orchids for the shaded garden. 
Small Yellow Ladyslipper—12 to 15 inch stems and flowers 
with bright yellow lips, madder purple sepals and petals, 
the latter twisted. 75c and $1.00. 
Large Yellow Ladyslipper—15 to 20 inch2s and more hairy. 
Larger, bright yellow lips and greener and less twisted 
petals. 75c and $1.00. 
*Reginae (spectabile or hirsutum)—The Showy Ladyslipper, 
and the finest of the genus. Leafy stems, 12 to 24 inches 
high, bearing up to 4 very large flowers, white sepals and 
petals, and a white slipper with rosy-pink markings, dur- 
ing late Spring and early Summer. This species will tolerate 
a neutral soil and requires ample moisture. $1.00 and

CYPRIPEDIUM REGINAE 
DELPHINIUM 
DELPHINIUM *grandiflorum Blue Mirror (formerly cinereum) 
—One of the most valuable plants introduced in years. 
Spurless flowers of intensely luminous blue on 12 to 15 
inch, branching stalks from late Spring to mid-Summer. 
Full sun, light soil and good drainage. A hardy perennial 
which always sells on sight. 50c and 75c. 5 
DELPHINIUM—Tall Kinds. These hardy perennials are so well 
known that little need be said about their beauty and value 
in the garden. Few other cultivated plants produce such 
gorgeous and lavish displays of stately blooms during early 
Summer and frequently again in the Fall. Delphiniums are 
most effective in groups and even a small garden has room 
for a few. They are not “’fussy’’ but do require a spacing 
of about 2 feet to develop properly. Most types of soil are 
satisfactory if they are prepared thoroughly and deeply. 
Well rotted manure (or compost) and bone meal mixed 
with most loamy soils will usually grow excellent Del- 
phiniums. The soil must be kept moist but the plants will 
not live for long in soggy locations. It is important to cut 
the flower stalks to just above the foliage as soon as the 
blooms fade. Then give the plants a rest period by keep- 
ing them slightly dry for two or three weeks. As soon as new 
shoots appear, remove the remainder of the old stalks and 
water well. Digging the plants and resetting them in freshly 
prepared soil every third season will keep them vigorous.
