Horticultural Achievement At Its Best 
Two Exceptional Flower Seed Novelties for 1940 
A New Race of Heat Enduring 
SPRING FLOWERING SWEET PEAS 
A much desired, long sought for reality. A Sweet Pea that will grow 
and flower successfully in sections of the country where other varieties 
fail on account of hot, dry weather. 
The three varieties offered here are 1940 All America Award Winners. 
BLUE (BRONZE MEDAL) 
4403 A clear marine blue about the color of Early Mariner. It is one 
of the most vigorous of the new Spring Flowering Sweet Peas, 
and the strong growing vines produce a wealth of flowers on long 
stout stems. When tested under hot weather conditions, Spring 
Flowering Blue performed splendidly................. Pkt. 25c 
LAVENDER (HONORABLE MENTION) 
4407 An appealing shade similar to that of Early Memory or to the 
Late Spencer varieties, King Lavender and Powerscourt. The 
beautiful clear lavender flowers are borne on long strong stems, 
one of the outstanding characteristics of the new Spring Flower- 
ing type. The growth is always encouragingly vigorous even 
under hot weather conditions, and a heavy crop of flowers is 
produced over a long period. A charming companion to Spring

ROSE PINK (SILVER MEDAL) 
4411 The blossoms of this grand variety are a beautiful clear rose 
pink, a shade between Early Giant Rose and Shirley Temple. 
Its outstanding merits are great vigor of growth, ability to grow 
successfully under hot weather conditions, unusually long stems. 
and its heavy crop of flowers and long season of production. It 
is a splendid variety for commercial greenhouse growers who de- 
sire long-stemmed flowers in winter from June sowings and late 
spring flowers from late fall sowings................. Pkt. 25c 
Plants are offered on pages 102 to 123. 
HENDERSON’S NEW IPOMEAS 
GREATER GLORIES 
Shown in Colors on Front Cover 
Largest and Most Beautiful Morning Glories 
The selection, segregation, and hy bridization of thousands of the most 
desirable and most beautiful flowers obtained from the finest strains 
of Imperial Hybrid Ipomeas, over a period of six years, resulted in 
the development of a great number of hybrids, many of which pos- 
sessed outstanding characteristics. Through the process of elimination, 
the six varieties offered here, were finally chosen as the most represen- 
tative, and the most beautiful of the group. 
Besides producing a luxuriant growth which during the course of the 
season attains a height of from 15 to 20 feet, the plants are extremely 
free blooming, and as is unusual with other varieties of Ipomea the 
flowers which range from four to five inches in diameter are developed 
over the entire plant, beginning about a foot from the ground. 
The plants are clothed from top to bottom with attractive three-lobed 
leaves, which adds much to their beauty. Henderson's Greater Glories 
are among the most desirable annual vines that may grace the Gardens 
of America. Wherever plant material is required for drapes or for 
screening purposes, nothing finer could be desired. For garden en- 
closures, they will make a wall of living beauty that will be a joy 
throughout the summer. They can be used for covering fences of 
every description, also stone walls, dead trees, poles, etc. There is no 
garden wherein they cannot be used to good advantage.
