Sweet Peas 
With the continually increasing number of sweet pea types being 
introduced there is inevitably a certain amount of confusion be- 
tween classes. To make the types as clear as possible and to 
introduce new classes in their proper position, we summarize here 
the three broad classfiications of early, spring and late with the 
new Zvolanek types in their proper location. 
EARLY 
(Winter Flowering) 
This group of sweet pea varieties includes only those which 
will flower under short-day conditions. In mild climates these are 
fall-planted for bloom from Christmas onward. In areas with 
severe Winters they are planted as early as possible in the spring 
and provide the first flowers, although not nearly so much earlier 
as when fall planted. The usual series in this class is the Early 
or Winter Flowering Spencer, and a very wide range of colors is 
available in this group. Newer, and more vigorous in plant as 
well as carrying more florets per stem is the Zvolanek Multiflora 
series. 
SPRING 
The Cuthbertson Spring Flowering group is well known for its 
greater vigor and greater heat resistance than comparable ma- 
turities. While this is not a short-day type and will not be rushed 
into bloom even in mild climates until the days become long 
enough, it does provide the best answer to reliable sweet pea 
crops where spring planting is the rule and where early summer 
heat is a hazard. Cuthbertson Floribundas are the newer, stronger 
varieties in this class. Zvolanek Floribundas belong in this same 
maturity class, and their characteristically longer, stronger stems 
and greater number of florets per stem make them a very inter- 
esting and worth-while addition to the sweet pea family. These 
are very new and in limited distribution as yet. Both types bloom 
about 2 weeks earlier than the late flowering types. 
LATE 
(Summer Flowering) 
Where cool weather persists during the summer this group is the 
most satisfactory for it has the largest plants and produces the 
heaviest crops of all. The standard strain is Late or Summer Flower- 
ing Spencer, and a long list of varieties is available. In this same 
classification is the brand new Zvolanek Plentiflora series. These 
varieties are available only in strictly limited quantities this year, 
but they exhibit the same advantage in number of florets in 
comparison with the Spencers as the other, earlier Zvolanek in- 
troductions.
