Sweet Pea evolution is constantly producing additions to the glorified 

 race of "Spencers" soon destined to supersede the older types, and in this 

 collection we include a number of the most recent. 



The characteristics of the Spencer Sweet Peas, grown under congenial 

 conditions, are: robust growth, the plants attaining a height of from 

 6 to 10 feet, requiring for full development to be from six inches to a foot 

 apart. The flowers are giants among Sweet Peas, measuring 2 to 2J4 

 nches across. They are beautifully formed with huge standards, open 

 and upright, and immense wings gracefully poised. Both standards and 



wings are daintily waved, the undulations reflecting high lights and 

 casting shadows in the depth, thus showing a varied harmony of tones 

 which greatly enhances the coloring. Three and often four of these 

 queenly blossoms are borne on long, strong stems, rendering them unsur- 

 passable as cut flowers for vases, bouquets and other decorations. Their 

 long-continued profusion of bloom is phenomenal, but accounted for by 

 the fact that a majority of the flowers of true Spencers fall as they fade- 

 before the seed pod is formed — thus continuing the succession of bloom — ■ 

 for as all know when Sweet Peas set pods, the flowering diminishes. 



Henderson's "Supreme" Collection Chosen by the Floral Committee of the 



National Sweet Pea Society 



In offering this collection, we do so in the full confidence that it is without question the best selection of Sweet Peas that it is possible to group. 

 This claim is made not only on our own recommendation, but also on that of the highest authority on Sweet Peas, namely: The Floral Committee of 

 the National Sweet Pea Society, who at their annual meeting in London last year those the varieties in the "Supreme" collection as the best in each 

 of the color classes.

Brief Cultural Directions 



Sowing Sweet Pea Seeds in the Open Ground: When Sweet Peas 

 are to be grown from start to finish in the open ground the seeds should 

 be sown at the earliest possible date in spring, even before frosts are over, 

 for they are quite hardy. But of course this cannot be done until the 

 ground is dry enough to work, i.e., is crumbly, not wet and sticky. The 

 object of early sowing is to give the roots as long a time as possible to 

 develop before the warm weather excites the tops into rapid growth. 

 Slow sturdy top growth and a well developed root-system, roots clear 

 down to the cool, rich, moist lower layers of soil before hot weather, is 

 one of the secrets of success. After the ground has been prepared, raked 

 and leveled, draw a flat furrow with a hoe about 6 inches wide and 

 3 inches deep and plant the seeds 2 to 3 inches apart zigzag along the 

 center of the furrow, cover with about 1 inch of soil, tfien tramp firm 

 with the feet; this will leave the seeds in a light depression which will 

 hold moisture and hasten germination. When the seedlings have attained 

 a height of 2 to 3 inches they should be thinned out to remain 6 to 12 

 inches apart, the greater distance is advised for trench culture if the 

 plants are expected to develop to their maximum capacity. Cultivation 

 should begin just as soon as the plants are large enough to keep the 

 surface of the ground loose, admit air and conserve the soil's moisture. 

 At each of the earlier hoeings draw a little of the ridged soil into the 

 furrow about the plants until it is all level. This gets the roots down 

 deeper where they are less susceptible to the drying out effects of hot 

 weather. We do not believe in ridging up the young seedlings as ridges 

 turn the water away. The vines are of course to be supported by brush 

 or netting.
