TULIPS 
The Classification of Tulips 
As the Tulip has been a very popular garden flower and in large commercial 
demand for over 250 years, there has naturally been a great production of 
varieties. The number of varieties listed in Holland catalogues, all told, 
approaches the 2,500 mark. Their classification is therefore complicated, and 
more or less artificial. A committee of the Royal Horticultural Society of 
England in 1917 drafted a classification, which is briefly explained in the descrip¬ 
tions given in our catalogue, in the belief that tulip growers will be interested 
and helped to a better understanding of the characteristics of varieties. 
According to the R.H.S. classification, Tulips are divided into three classes: 
I. Native, or natural-growing species. II. Early Flowering. III. Late, or 
May Flowering. 
The native species of Tulips are those original native species growing in 
Europe, Asia, England, etc. It is from these that the numerous horticultural 
varieties have been derived. 
The Early Flowering Tulips comprise: (1) Single Early Tulips; (2) Double 
Early Tulips; (3) Due Von Tholl Tulips. 
The Late or May Flowering Tulips comprise groups known as: (1) Darwins; 
(2) Breeders; (3) Cottage Tulips; (4) Parrots; (5) Rembrandts; (6) Byblooms; 
(7) Bizarres; (8) Late Double Tulips; (9) Lily Flowered Tulips; (10) Mendel 
Tulips; (11) Triumph Tulips; (12) Ideal Tulips. 
Darwin Tulips 
The culture of these Late Tulips has developed in recent years into a fad 
amongst flower growers, as their beauties and merits have become recognized. 
They were named in 1889 after the great English naturalist, Charles Darwin. 
Some years previous they had been originated by an unknown amateur, in the 
north of France. 
The bloom is borne on strong, stately stems 18 to 30 inches in length. 
Their range of colors embraces almost every conceivable tint of rose, heliotrope, 
claret, maroon, crimson and rich shades of purple approaching a black and 
Yellow and White Darwins have been developed also. The flowers of Darwin 
Tulips are large, globular and of heavy texture. As cut flowers they are much 
used and very satisfactory. They are most valuable for permanent planting 
in borders and amongst shrubbery. They show best in clusters, and will continue 
to bloom for years. 
From the many hundreds of varieties on the market, we list only the 
following varieties. We can commend the selections as containing the best of 
the best. For customers, unacquainted with varieties, we recommend the 
purchase of Parcel Lots. 
The letters E, M and L used in the descriptions, represent Early, Medium 
and Late respectively. The numbers represent the height in inches. It is 
hardly necessary to state that these letters and numbers suggest only the 
approximate, relative and probable time of blooming and heights. 
Favorite varieties are printed in capitals. This does not mean, however, 
that the other varieties are less desirable or attractive. It means only that 
those printed in capitals are popular favorites and well recommended. 
Why not order now ? It is not too early.
